Many current standard laboratory methods and assays can benefit from digital photography to capture, quantify, and digitise results but this can be time-consuming and not automated without dedicated imaging systems. While some commercial systems exist for specific common applications, such as electrophoresis gel documentation, these can be expensive and are typically tailored to particular setups (e.g., UV or blue-fluorescent illumination). This limits digital imaging to particular assays, the cost can be a barrier to access, and large expensive benchtop instruments are unsuited to carry outside of the lab and into the field. The number of uses of digital imaging - often exploiting consumer products such as smartphone cameras is rapidly expanding within many biological and chemical sciences. For example, smartphone colourimetry [1], illustrates how analysis of spectral changes in reporter dyes used widely in biological and chemical assays, can be transported away from spectrometers, imaging processing software quantify colour from RGB digital images and convert them into absorbance values. Within microbiology, colourimetry and turbidity can be used to detect and measure bacterial growth. Likewise in chemical analysis [2], where once semi-qualitative approaches to comparing colour change by eye can be replaced with more sophisticated and quantitative image analysis using digital imaging. The development of Digital Image Correlation (DIC) techniques is becoming popular in fields including crystallography [3]. As digital cameras become cheaper, a move from laboratory instruments (e.g. CCD cameras) to consumer cameras offers a simplified approach to producing scientific imaging devices, remaining sensitive yet cost-effective in a resource-limited setting, from chemical sensors [4] to phenotypic identification of bacteria [5]. Often, however, data quality is restricted by manual camera operation to take images with a digital camera or smartphone camera. Although the use of a tripod or frame to support the camera can stabilise image capture, consumer cameras with proprietary control firmware can be tricky to control offering limited or unreliable time-lapse options. Automation of these processes can therefore greatly increase the number and quality of images recorded and reduce the hands-on time needed to take the images. There have already been several advances across different fields highlighting how automation reduces time in the field and allows for the preservation of data integrity [6], [7]. Another trend is toward portability, to take lab measurements outside the lab and into the field [1]. Indeed, the increasing popularity of smartphone capture for many diverse assays [8], [9] suggests that the rapid development of customisable, precise imaging devices will offer a portable format for experimental imaging in many experimental fields.

Screening and imaging are often found within clinical microbiology labs, but although automation has been extensively adopted in clinical diagnostic labs, it remains expensive and/or laborious in smaller labs or research areas that do not use the core standardised assays required in clinical testing [10], [11]. Here we introduce why microbiology methods are important, and yet outside the best-funded clinical labs, limited instruments are available, and flexibility is key. Due to the specialism of many microbiological samples, and the range of different ways in which experiments are carried out, customisable imaging and analysis systems are vital. A range of different sample formats may be required for analysis, even when core methods remain the same. For example, testing mastitis milk samples in an agricultural setting will require a distinct set of analytical microbiology assays to identify and test antibiotic susceptibility of bacterial pathogens, to human clinical samples. Yet in both cases, core assay equipment, multi-well plates, and Petri dishes remain identical requiring quantitation of colour changes that indicate microbial identification, in a range of different devices and conditions. Recent innovations have shown that traditional large devices can be replaced by smaller devices including custom 3D printed labware [12] down to the smallest sample volumes being assessed within microfluidic devices [13], [14] and droplet microfluidics [15], [16]. Flexibility and customisation are therefore vital for a lab imaging platform to be useful for as many different applications as possible. One of the most important analytical microbiology methods is the identification of antimicrobial resistance (AMR) in a wide range of samples. Currently, these assays either require skilled laboratory technicians or expensive automated instrumentation, both of which are operated within an appropriate lab environment. This highlights that simplicity in the way we image and analyse assays is required outside of larger-scale labs where funds are extensive, and the sample throughput is high.

When addressing problems such as AMR on farms, treatment is almost always carried out before microbiological testing, days before AMR would be identified. This historically has contributed to a continual build-up of AMR on farms due to the overuse or inappropriate use of antibiotics [17], [18]. A more flexible and rapid approach is required to tackle these problems. Flexible time-resolved automated imaging could therefore become important in agriculture, for example supporting the development of more rapid AMR tests ideally measuring bacterial resistance to antibiotics directly from the sample. For use in the dairy industry, it would be ideal to analyse milk samples from dairy cows with mastitis for antibiotic resistance. Potential use for this device would be to image antibiotic susceptibility assays in mastitis milk samples. Portable, timelapse imaging would therefore be able to determine AMR more rapidly on-farm, highlighting the usefulness of PiRamid outside of the lab. Moreover, the importance of kinetics in microbial growth analysis has been shown by the existence of much more costly and sophisticated in-house laboratory imaging systems, however, the simplicity and automation of PiRamid may prove useful for a much quicker and simpler way of analysing AMR on dairy farms in the future.

Microfluidic devices are now more widely used in the detection of pathogenic species of bacteria, with their use allowing for greater speed of detection and the development of point-of-care diagnostics, able to be used in the field. Whether this be within the detection of urinary tract infections (UTIs) [13] or for the portable detection of bacteriophage lysis [9]. Our group developed a simple, low-cost example microfluidic device that can be used to detect bacterial growth and measure multiple antimicrobial resistance profiles of bacteria using the metabolic sensitive dye, resazurin [14] able to detect bacterial growth by a colour change from blue to pink. The devices used are made from a melt-extruded highly transparent fluorinated ethylene propylene co-polymer (FEP-Teflon) microcapillary film (MCF) comprising 10 capillaries along its length. This method allows for the use of high-throughput microfluidic devices, termed ‘lab-on-a-comb’, compatible with existing laboratory equipment such as 96 well microtitre plates [9], [14], [19]. The use of microfluidic devices can provide detailed information on bacterial growth, morphology, and kinetic effects of substances on bacterial species, which can prove beneficial to phenotypic analysis for both research and clinical applications (e.g., identify pathogens and choosing antibiotic treatment for UTIs, and AMR surveillance). Previously the reliance on expensive plate readers to collect this data was time-consuming and labour-intensive, replacing plate-readers with time-lapse cameras could easily increase throughput, reduce labour time and increase flexibility since different formats can be tailored to specific needs.

To address this, we have seen the development of open-source imaging devices, exploiting the use of 3D printing and utilising robotics [6], [19]. Devices such as the one described by Needs et al. [19] allow for fully customisable and high throughput imaging of both low-cost microfluidics and conventional MTP and Petri dishes. Others have developed open-source hardware to obtain the same outputs at lower cost, or when proprietary commercial instruments are not suited to novel configurations [20], [21], [22]. These could replicate or improve on established analytical microbiology systems based on reagent-loaded 96 wells plates, including those for kinetic analysis of single plates or up to 50 microtitre plates, which are monitored every 15 min [23]. The success of these commercial devices proves the value of kinetic microbial growth analysis, but the instrumentation is not widely available to most labs due to cost and specialism of experiment format, as only a few labs process enough plates to justify the capital investment in this dedicated instrument.

We propose “PiRamid” an imaging system that was designed to exploit low-cost desktop fused-filament deposition (FFD) 3D printing and simple python script programming to produce a compact, low-cost, high-performance system for automated laboratory imaging. The design centres around the simple to use and low-cost Raspberry Pi single-board computer system and associated camera. LED sample illumination is powered by GPIO pins. The system is controlled by basic Python scripts based on the widely documented PiCamera camera control library. The device is fully customisable, with the 3D printed case stacking for ease of opening, designed using OpenSCAD open-source CAD software. This design is compact and can be portable for use in the field, whilst maintaining the same automation as when used in the laboratory if powered using inexpensive consumer lithium battery packs sold typically as smartphone chargers. To make it compact, the device is scaled down to allow for easier transportation and storage; this does limit the imaging area and restricts the number of samples that can be simultaneously imaged. Importantly, the small size allows it to be used inside standard table-top microbiological incubators for controlled temperature, without requiring either a large incubator facility or built-in heading and temperature control. Although open-source incubator designs exist, and low-cost PID controlled incubators can maintain a suitable temperature for microbiological experiments [24] we avoided adding an incubator to the PiRamid to make it as simple to assemble and program as possible.

The simple system is capable of taking time-resolved images of samples of different microbiological based assays that can be performed in microfluidic devices, strip wells, and custom agar device designs. We provide validation data of its uses within different scientific fields and across different methods. With the use of microfluidic MCF, PiRamid can image up to 24 different bacterial isolates, with up to 240 different conditions (10 capillaries per isolate). Due to the ease of production and use, it would be more than appropriate to build and use multiple devices for larger experiments. This would still be cost-effective, more flexible in use and provide greater portability. Even with the average cost of an individual device ranging from ~£120 to ~£180, we can expect the production of four of these devices to cost ~£480 to ~£720, and capable of imaging up to 960 conditions. Conventional lab-based assay readers and spectrophotometers can cost far in excess of £3000 each, often analysing one individual 96-well plate at a time and incapable of capturing growth kinetics; plate readers with inbuilt incubation plus time-resolved scanning might even cost £10,000 or more, and most plate readers are too bulky to fit in microbiological incubators.
