Label-free trace detection of bio-molecules by liquid-interface assisted surface-enhanced Raman scattering using a microfluidic chip
文献摘要:
Surface-enhanced Raman scattering (SERS), owing to its high sensitivity based on localized surface plasmon reson-ance of nanostructured metals, is recently attracting much attention to be used for biotechnology, such as cell imaging and tumor therapy. On the other hand, the trace detection of bio-molecules with large molecular weight is still challen-ging because the troublesome treatment of SERS substrate using coupling or cross-linking agents is required. In this pa-per, we apply liquid interface assisted SERS (LI-SERS) method, which provides unique features of collection and self-im-mobilization of analyte molecules on the SERS substrate, to realize the label-free trace detection of bio-molecules with detection limits of pM ~ fM. Specifically, deoxyribonucleic acid (DNA) discrimination and quantitative detection of β-Amyl-oid (Aβ) in trace-concentration are demonstrated to illustrate the ultrahigh sensitivity and versatility of the LI-SERS meth-od. The results suggest LI-SERS is promising for the early-stage diagnosis of diseases such as virus infection and Alzheimer's disease.
