Nanofluidic Diagnostic Chip: Resistive-Pulse Molecule Sensing

Interactive 3D nanofluidic sensing chip: DNA fragments, proteins and virus-like particles drift through a nanochannel constriction, each transiently blocking the ionic current so its size can be read from the depth and duration of the current dip.

DNA fragments, proteins and virus-like particles drift from a reservoir through a nanochannel narrow enough that each molecule briefly blocks a measurable slice of the ionic current as it squeezes through the constriction. The live oscilloscope trace records every translocation as a current dip — depth and duration reveal the particle's size and identity without ever imaging it directly. Dial voltage, channel diameter, flow rate and electrical noise to see how each trades off detection speed against how cleanly the three species can be told apart on the trace.
