Capture Agent Free Biosensing using Porous Silicon Arrays and Machine Learning. (arXiv:2201.11671v1 [physics.med-ph])

Biosensors are an essential tool for medical diagnostics, environmental
monitoring and food safety. Typically, biosensors are designed to detect
specific analytes through functionalization with the appropriate capture
agents. However, the use of capture agents limits the number of analytes that
can be simultaneously detected and reduces the robustness of the biosensor. In
this work, we report a versatile, capture agent free biosensor platform based
on an array of porous silicon (PSi) thin films, which has the potential to
robustly detect …
