We designed the nPLEX sensor to achieve label-free detection of exosomes of this size, where the basic sensing unit consists of a periodic lattice of nanoholes patterned in a gold (Au) film.

“We present a CMOS-compatible double gate and label-free C-reactive protein (CRP) sensor, based on silicon on insulator (SOI) silicon nanowires arrays. We exploit a reference subtracted detection ...
