Colloidal self-assembly refers to a solution-processed assembly of nanometer-/micrometer-
sized, well-dispersed particles into secondary structures, whose collective properties are …

The discovery of the enhancement of Raman scattering by molecules adsorbed on
nanostructured metal surfaces is a landmark in the history of spectroscopic and analytical …

Surface plasmon resonance (SPR) has found extensive applications in chemi-sensors and
biosensors. Plasmons play different roles in different types of optical sensors. SPR …

Background: CRISPR-Cas12a has been integrated with nanomaterial-based optical
techniques, such as surface-enhanced Raman scattering (SERS), to formulate a powerful …

We demonstrate the synthesis of Au nanostar dimers with tunable interparticle gap and
controlled stoichiometry assembled on DNA origami. Au nanostars with uniform and sharp …

Surface-enhanced Raman scattering (SERS)-based biosensors are promising tools for virus
nucleic acid detection. However, it remains challenging for SERS-based biosensors using a …

Dopamine (DA) is a neurotransmitter which plays a key role in the life science. Self-
assembled Au@ Ag nanorod dimers based on aptamers were developed for ultrasensitive …

A sensitive surface-enhanced Raman scattering (SERS) signal dependent double detection
of mycotoxins is achieved for the first time, without the aid of nucleic acid amplification …

Surface-and tip-enhanced Raman spectroscopy (SERS and TERS) techniques exhibit
highly localized chemical sensitivity, making them ideal for studying chemical reactions …

This review focuses on recent developments in hybrid and nanostructured substrates for
SERS (surface-enhanced Raman scattering) studies. Thus substrates composed of at least …
