Label-Free Biosensing over a Wide Concentration Range with Photonic Force Microscopy

Seungjin Heo, Prof. Kipom Kim and Prof. Yong-Hoon Cho

We present a label-free biosensor that measures molecular interactions between biomolecules on the surface of a probe bead and substrate over a wide concentration range. This system is capable of detecting target biomolecules with concentrations varying from 10 nm to 0.1 pm, with high selectivity and sensitivity.
