Facile one-pot synthesis of Au(0)@Au(i)–NAC core–shell nanoclusters with orange-yellow luminescence for cancer cell imaging

Abstract

The core–shell AuNCs synthesized by a facile strategy using NAC as reducing-cum-protecting agent were successfully applied for cancer cell imaging.

Selective and sensitive colorimetric detection of the neurotransmitter serotonin based on the aggregation of bifunctionalised gold nanoparticles

“…8.74 x 10 -10 M from an estimated molar extinction coefficient of ε = 3.97 x 10 8 M -1 cm -1 [53]. The FTIR studies showed the appearance of absorption bands which were attributed to NALC (C=O stretching at 1649 cm−1, N-H bending at 1543 cm−1 and N-H stretching at 3352 cm−1), as reported in other studies [54], and DSP's C=O stretching also appeared at 1720 cm −1 [55] (see Figure S3). 1 H-NMR spectra also showed the appearance of signals, which were attributed to the functionalisation with NALC and DSP.…”

Atomically Precise Colloidal Metal Nanoclusters and Nanoparticles: Fundamentals and Opportunities

“…Among these properties, the luminescence properties of nanoclusters of gold (see refs , , , , , and − ), silver, − copper, − and bimetals − have received enormous interest. Most such nanoclusters are typically prepared by methods such as templating, etching, microwave-facilitated synthesis, and ligand or surfactant control. ,,− Silver nanoclusters are often more luminescent than gold ones. , Luminescent nanoclusters have found tremendous applications in nanomedicine, − such as bioassays of DNA/protein, , immunorecognition and pharmacokinetics, biolabeling and cellular imaging, − chiral recognition, dual-modal fluorescence/X-ray computed tomography imaging, drug delivery, cancer therapy, − and environmental monitoring and chemical sensing, − ,, The luminescence of nanoclusters is affected by a number of factors,…”
