Abstract: Abstract Label-free detection has promising applications in biomedical and analytical fields. Localized surface plasmon resonance (LSPR) of gold (Au) nanoparticles is sensitive to the dielectric constant of the surrounding environment. Therefore, the LSPR-based (or plasmonic)… read more here.

DOI: 10.1021/acsomega.2c04259
Abstract: Gold nanoparticles (AuNPs) are commonly synthesized using the citrate reduction method, reducing Au3+ into Au1+ ions and facilitating the disproportionation of aurous species to Au atoms (Au0). This method results on citrate-capped AuNPs with valence… read more here.
