Highly selective and sensitive surface-enhanced Raman scattering sensors for the detection of peroxynitrite in cells

Abstract

In the physiological and pathological process, evaluating the role of peroxynitrite (ONOO–) in living cells with high sensitivity and selectivity is a significant challenge. In this study, a highly sensitive...

Electrically configurable SERS-FET for the highly sensitive and selective detection of molecules

“…Conventionally, selective Raman enhancement was realized by electrostatic effects, antigen–antibody reactions or DNA pairing. 22–25 But recently, Liang et al effectively controlled the μ CT process by using defect level engineering through altering the band structure of boron carbon nitride (BCN). 26 The measurement results evidenced that the SERS substrates prepared with different defect densities of BCN selectively enhanced 20 different trace chemical and bioactive molecules, which demonstrates the great potential of SERS substrates for precise detection in analytical chemistry and biomedical fields.…”
