A method to perform in situ roughening of arrays of microstructures weakly adherent to an underlying substrate was presented. SU8, 1002F, and polydimethylsiloxane (PDMS) microstructures were roughened by polishing with a particle slurry. The roughness and the percentage of dislodged

The enzyme-linked immunospot assay (ELISPOT) is a technique widely used to enumerate the number of immune cells secreting a specific protein, such as antibodies or cytokines. A limitation with the ELISPOT assay is that it can only be used to
Herein we describe the orientation of GST-tagged lectins on NHS-activated slides via a one-step deposition of the protein and a glutathione (GSH) scaffold. This technology overcomes the need for a premade GSH-surface to orient GST-tagged proteins, enabling us to rapidly
Kinesin-1 motor proteins move along microtubules in repetitive steps of 8 nm at the expense of ATP. To determine nucleotide dwell times during these processive runs, we used a Förster resonance energy transfer method at the single-molecule level that detects
A dual-view imaging system for simultaneous four-color single-molecule (SM) detection was developed. As for the detection procedure, four species of SM fluorophores, namely, Alexa 488, 555, 647, and 680, are immobilized on different slides and excited by evanescent-wave illumination. Fluorescence
