SERS Hotspot Engineering by Aerosol Self-Assembly of Plasmonic Ag Nanoaggregates with Tunable Interparticle Distance. [PDF]
Adv Sci (Weinh), 2022 AbstractSurface‐enhanced Raman scattering (SERS) is a powerful sensing technique. However, the employment of SERS sensors in practical applications is hindered by high fabrication costs from processes with limited scalability, poor batch‐to‐batch reproducibility, substrate stability, and uniformity.

SERS Hotspot Engineering by Aerosol Self‐Assembly of Plasmonic Ag Nanoaggregates with Tunable Interparticle Distance (Adv. Sci. 22/2022) [PDF]
Advanced science, 2022 Pesticide Residue Detection In article number 2201133 by Georgios A. Sotiriou and co‐workers, flame aerosol technology is used for the rapid self‐assembly of uniform surface‐enhanced Raman scattering (SERS) sensing films. These robust nano‐sensors can detect pesticide residues on apple surface in a short time of 5 minutes without destroying the fruit ...

Utilizing Freeze-Thaw-Ultrasonication to Prepare Mesoporous Silica-Encapsulated Colloidal Silver Nanoaggregates with Long-Term Surface-Enhanced Raman Spectroscopy Activity [PDF]
SensorsSurface-enhanced Raman spectroscopy (SERS) is widely employed due to its high sensitivity and distinctive fingerprinting capabilities. Colloidal nanoaggregates are commonly used as SERS substrates because of their mobility and the abundance of “hotspots”.
