Non-fouling PEG silane monolayer was desorbed from individually addressable ITO electrodes on glass by application of a reductive potential. Electrochemical stripping of PEG-silane layer from ITO microelectrodes allowed for cell adhesion to take place in a spatially defined fashion, with cellular patterns corresponding closely to electrode patterns.

This protocol describes a solution-based fabrication strategy for high-performance, flexible, transparent electrodes with fully-embedded, thick metal mesh. Flexible transparent electrodes fabricated by this process demonstrate among the highest reported performances, including ultra-low sheet resistance, high optical transmittance, mechanical stability under bending, strong substrate adhesion, surface smoothness, and environmental stability.
FAQs
Optical transmission allows illumination to reach cells or tissues and enables returning light to travel toward detectors with less interference from the supporting surface. This can improve observation and measurement at the sample interface, making the substrate relevant to microscopy, live-cell imaging, and biosensing where the platform must support the sample without obscuring optical signals.
Selection requires balancing optical transparency with surface compatibility, mechanical stability, and chemical resistance. A substrate may transmit light effectively yet perform poorly if its surface does not suit the biological sample, if it lacks sufficient stability, or if it cannot tolerate the experimental chemical environment. Considering these properties together supports more reliable biological measurements.
Surface compatibility determines whether the supporting platform can function effectively with the biological sample and its interface. The substrate must provide a suitable surface while preserving the optical access needed for observation or measurement. This consideration is especially important in cell culture, biosensing, and experiments that examine interactions occurring where the sample meets the substrate.
Researchers should begin with the intended observation or measurement, then evaluate whether the substrate provides adequate light transmission for the selected imaging or sensing approach. They should also assess compatibility with the biological sample, mechanical stability during handling or culture, and resistance to the experiment’s chemical conditions. This selection process helps align substrate performance with experimental goals.
Optically transparent substrates support several biological applications, including cell culture, live-cell imaging, biosensing, and analysis of interactions at the sample interface. Their value varies with the experiment: they can provide a stable platform for growth, preserve access for imaging, or support measurements involving the boundary between a biological sample and its supporting surface.
These substrates can enable observation, measurement, and imaging while reducing interference from the support. In biological research, that capability contributes to examining cells or tissues, monitoring live samples, and analyzing interface interactions. The same combination of optical access and material stability also supports the development of advanced imaging and diagnostic platforms.
