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
These properties determine how strongly different regions scatter the electron beam. Thicker or denser areas generally transmit fewer electrons than thinner or less dense regions, while differences in atomic composition can also change scattering. The resulting variation in transmitted electrons produces image contrast, allowing membranes, organelles, viruses, and macromolecular assemblies to appear as distinct structural regions.
Section thickness directly affects whether electrons can pass through a specimen sufficiently to form a useful image. If thickness varies across a section, transmission also varies, creating contrast linked to specimen geometry as well as biological structure. Researchers therefore adjust section thickness to maintain electron transmission while preserving enough material to reveal ultrastructural detail.
Electron transparency controls the amount of the beam reaching the detector or imaging system from each region. Unequal transmission creates intensity differences that expose fine structure, but those differences may reflect thickness, density, or composition rather than one factor alone. Interpreting TEM images therefore requires considering how specimen properties contribute to the observed contrast.
Biological samples must be prepared as ultrathin sections so the electron beam can traverse them. Preparation also aims to preserve the specimen's relevant structure while maintaining suitable transmission across the section. Researchers adjust preparation conditions and section thickness according to the structures being examined, because poor transmission can reduce image quality and limit ultrastructural analysis.
They treat transmission as a central preparation and imaging criterion rather than an incidental property. Section thickness is adjusted to balance beam passage with retention of biological material, while differences in density and composition are preserved as sources of contrast. This approach improves the visibility of fine structures and helps determine whether a sample is suitable for ultrastructural imaging.
In biology, suitable electron transmission supports visualization of membranes, organelles, viruses, and macromolecular assemblies. These targets often require structural detail beyond what conventional light microscopy can provide. By enabling contrast from differences in thickness, density, and composition, the method helps researchers assess cellular and subcellular organization at ultrastructural scales.
