Simultaneous SERS detection and imaging of two biomarkers on the cancer cell surface by self-assembly of branched DNA-gold nanoaggregates.

A surface-enhanced Raman scattering (SERS) method has been proposed for simultaneous detection and imaging of two biomarkers on the surface of a single human breast cancer cell (MCF-7) by self-assembly of branched DNA-gold nanoaggregates.

Proximity-dependent isothermal cycle amplification for small-molecule detection based on surface enhanced Raman scattering.

A novel proximity-dependent isothermal cycle amplification (PDICA) strategy has been proposed and successfully used for the determination of cocaine coupled with surface enhanced Raman scattering (SERS). For enhancing the SERS signal, Raman dye molecules modified bio-barcode DNA and gold nanoparticles (AuNPs) are used to prepare the Raman probes. Magnetic beads (MBs) are used as the carrier of amplification template and signal output products for circumventing the problem of high background induced by excess bio-barcode DNA.

Sensitive SERS detection of DNA and lysozyme based on polymerase assisted cross strand-displacement amplification.

A novel surface-enhanced Raman scattering (SERS) assay is demonstrated by developing a cross strand-displacement amplification (CSDA) method to enhance the SERS signals. Highly sensitive and selective detection of any single-stranded DNA is achieved and an aptasensor for proteins is constructed.
