Recent advancements in ptychography have demonstrated the potential of coded ptychography (CP) for high-resolution optical imaging in a lensless configuration. However, CP suffers imaging throughput limitations due to scanning inefficiencies. To address this, we propose what we believe is a novel 'fly-scan' scanning strategy utilizing two eccentric rotating mass (ERM) vibration motors for high-throughput coded ptychographic microscopy. The intrinsic continuity of the 'fly-scan' technique effectively eliminates the scanning overhead typically encountered during data acquisition...

OBJECTIVE: Recent advancements demonstrate the significant role of digital microfluidics in automating laboratory work with DNA and on-site viral testing. However, since commercially available instruments are limited to droplet manipulation, our work addresses the need for accelerated integration of other components, such as temperature control, that can expand the application domain. METHODS: We developed PhageBox- an accessible device that can be used as a biochip extension...

Synthetic biology (SynBio) is a rapidly advancing multidisciplinary field in which South American countries such as Chile, Argentina, and Brazil have made notable contributions and have established leadership positions in the region. In recent years, efforts have strengthened SynBio in the rest of the countries, and although progress is significant, growth has not matched that of the aforementioned countries. Initiatives such as iGEM and TECNOx have introduced students and researchers from various countries to the foundations of SynBio...

Standard molecular biology laboratories are usually made with complex, sophisticated, and expensive equipment. Unfortunately, most of these labs are not affordable for everyone. In this paper, we show how we built a portable bio lab BioBlocksLab, made of four modules: a centrifuge, a thermocycler, electrophoresis, and an incubator. We also propose a new version of a blockly programming language to describe experimental lab protocols, called BioBlocks 2.0, which is based on the Microsoft MakeCode platform from the open-source project Microsoft Programming Experience Toolkit (PXT)...

PytuTester is an open-source ventilator tester developed to help bio-engineers in the design and verification of new ventilator prototypes. A ventilator tester allows measuring the flow, pressure, volume, and oxygen concentration provided to the patient. During the global pandemic COVID-19, several open-source ventilators prototypes were developed; however, due to high cost and demand testers, they were not available. In this context, a low-cost tester was developed using a Raspberry Pi and medical-grade sensors for the test ventilators prototypes...

BACKGROUND: User-developed automated insulin delivery systems, also referred to as do-it-yourself artificial pancreas systems (DIY APS), are in use by people living with type 1 diabetes. In this work, we evaluate, in silico, the DIY APS Loop control algorithm and compare it head-to-head with the bio-inspired artificial pancreas (BiAP) controller for which clinical data are available. METHODS: The Python version of the Loop control algorithm called PyLoopKit was employed for evaluation purposes...

A sustainable three-electrode platform for affordable microfluidic electroanalysis is described. The device can be handmade using common tools and, facilitating broad applicability, is indefinitely reusable through simple surface polishing. Compact prototypes with Pt counter, Pt working, and Ag/AgCl reference electrode disks were combined with silicone lid plates containing a microchannel for electrolyte flow. Redox voltammetry/amperometry of excellent quality was achieved in static and flowing ferricyanide solutions, respectively...

Policymakers should treat DIY-biology laboratories as legitimate parts of the scientific enterprise and pay attention to the role of community norms.

This protocol details the construction of a simple, low-cost, small-scale, multiplex chemostat system designed for the continuous cultivation of microorganisms in suspension ( i.e. , bacteria, yeast, microalgae). The continuous culture device can operate at a working volume of 25 ml and allows the run of 8 chemostats in parallel by a single person. It provides a platform for parallel, long-term studies of evolution and adaptation of microorganisms under the stress of antimicrobial agents and/or toxic pollutants...

The speed and scale of the COVID-19 pandemic has highlighted the limits of current health systems and the potential promise of non-establishment research such as "DIY" research. We consider one example of how DIY research is responding to the pandemic, discuss the challenges faced by DIY research more generally, and suggest that a "trust architecture" should be developed now to contribute to successful future DIY efforts.

Since 2008, we witness the emergence of the Do-It-Yourself Biology movement, a global movement spreading the use of biotechnology beyond traditional academic and industrial institutions and into the lay public. Practitioners include a broad mix of amateurs, enthusiasts, students, and trained scientists. At this moment, the movement counts nearly 50 local groups, mostly in America and Europe, but also increasingly in Asia. Do-It-Yourself Bio represents a direct translation of hacking culture and practicesfrom the realm of computers and software into the realm of genes and cells...

The rise of amateur biologists in Europe. Biotechnology is no longer the unique realm of traditional venues such as university or industry labs. In recent years a growing number of Do-it-yourself Biology (DIY-Bio) groups established themselves in Europe. On pages 548-551 of this issue, Seyfried et al. analyze the DIYBio community in Europe and provide an insight into the structure, challenges and aspirations of amateur biologist. In contrast to the hope (next generation of entrepreneurs), hype (regarding their technical skills), or horror (safety and security risks) usually ascribed to DIYBio, the authors reveal a realistic assessment of a small dedicated core group of semi-professionals trying to establish an open access version of biotechnology...

The encounter of amateur science with synthetic biology has led to the formation of several amateur/do-it-yourself biology (DIYBio) groups worldwide. Although media outlets covered DIYBio events, most seemed only to highlight the hope, hype, and horror of what DIYBio would do in the future. Here, we analyze the European amateur biology movement to find out who they are, what they aim for and how they differ from US groups. We found that all groups are driven by a core leadership of (semi-)professional people who struggle with finding lab space and equipment...
