2019
Microplate Assistive Pipetting Light Emitter (M.A.P.L.E.) is a computer-driven device that systematically illuminates microtiter wells to provide guidance for the manual preparation of microplates. M.A.P.L.E. improves the accuracy of microplate preparation while automating data recordkeeping. In addition, it can assist with examining microplate quality or aid in the detection of errors.

2024
Wood panel products are essential materials used in construction for applications such as flooring, siding, and roofing, typically available in standard dimensions of 4 feet by 8 feet, with thicknesses varying from one-quarter of an inch to one and one-eighth inches. Among the most common types of wood panels is plywood, which is produced by gluing multiple layers of thin wood veneers under pressure. The grain of the outer veneers runs lengthwise, while the grains of the interior layers run...

Source: Weber, N. et. al., Natural Transformation, Protein Expression, and Cryoconservation of the Filamentous Cyanobacterium Phormidium lacuna. J. Vis. Exp. (2022)This video demonstrates a focused LED-based assay for studying phototaxis in filamentous cyanobacteria. The bacteria migrate toward the light source, forming a dense accumulation at the illuminated center, which is visualized and quantified through pixel intensity analysis of the captured image.
FAQs
The light sources establish the panel’s spatial arrangement, while the control electronics regulate illumination intensity, timing, and spectral output. Coordinating these elements lets investigators tailor exposure to cells, tissues, or optical measurement systems rather than relying on a single fixed lighting condition. This control supports experiments that require consistent spatial or temporal illumination across repeated measurements.
Researchers can adjust intensity, timing, and spectral output to match the requirements of a biological assay or optical measurement. Spatial arrangement also affects where illumination is delivered, while temporal control determines when exposure occurs. Managing these variables helps produce more consistent conditions for experiments involving cells, tissues, imaging, or photostimulation.
Shared hardware designs, control methods, and construction details allow laboratories to inspect, modify, and reuse a panel rather than treating it as an inaccessible fixed system. In bioengineering, this openness can improve transparency and reproducibility because researchers can work from the same underlying design while adapting dimensions or operating behavior to a specific assay or laboratory configuration.
Researchers can use the shared hardware, control methods, and construction details as a starting point, then modify the panel for the needs of a particular assay, instrument arrangement, or laboratory space. Adjustments can target light-source arrangement, intensity, timing, or spectral output. This approach supports rapid prototyping without requiring every laboratory to develop an illumination platform independently.
The platforms can support biological imaging, photostimulation, and experiments involving cells or tissues. They can also provide controlled illumination for optical measurement systems, where consistent light conditions are important for collecting comparable observations. Because researchers can modify the design and control behavior, one platform can be adapted across different assays and experimental configurations.
Openly available designs can support low-cost prototyping by allowing laboratories to reuse and modify existing hardware, control methods, and construction details. This flexibility is especially useful when commercial illumination systems do not match a laboratory’s assay or configuration. Shared designs also promote transparency, helping researchers document and reproduce customized lighting systems across resource-limited settings.
