Rapid synthesis of Au/Ag bimetallic nanoclusters with highly biochemical stability and its applications for temperature and ratiometric pH sensing

Isostructural Single- And Dual-Lanthanide Metal–Organic Frameworks Based On Substituent-Group-Modifying Tetracarboxylate Ligands for Ratiometric Temperature Sensing

“…1,2 Its precise measurement is thus of great significance in scientific research and technological developments as well as industrial manufacturing. Conventional temperature probes, such as thermocouples, 3 thermistors, 4 and liquid and bimetallic thermometers, 5 have limitations as they require direct contact with the object and can thus perturb its temperature. In fact, current demands in nanomedicine, microelectronics, microfluidics, photonics, etc., have reached a stage where contact thermometry is not appropriate for temperature measurements at micro-and nanoscales and complex electromagnetic and fast-moving conditions.…”

An endogenous stimulus detonated nanocluster-bomb for contrast-enhanced cancer imaging and combination therapy

“…To validate the stability and anti-inference ability of the L-AuNC-based nanocarrier system, 8% PAGE was performed aer L-AuNCs/Dzs was incubated in 10% FBS at 37 Cell culture MDA-MB-231 cells (human breast carcinoma) and MCF-7 cells (human breast carcinoma) were obtained from the cell bank of Central Laboratory at Xiangya Hospital (Changsha, China), and cultured in Dulbecco's Modied Eagle Medium (DMEM) supplemented with 10% (v/v) fetal bovine serum (obtained from Invitrogen) and 100 IU mL À1 penicillin-streptomycin. L02 cells (normal human hepatic cell line) were cultured in 1640 medium and MCF-10A cells (normal human mammary epithelial cell line) were grown in DMEM/F12 medium (Procell Life Science & Technology Co., Ltd.) supplemented with 5% HS, 20 ng mL À1 EGF, 10 mg mL À1 insulin, 0.5 mg mL À1 hydrocortisone, 1% NEAA, and 1% P/S solution.…”

“…24 The results displayed new potential of AuNCs which served as an activable reporter. More importantly, as for a nanocarrier, a simple synthetic route and multiple bio-ligands are available for AuNC synthesis, 33,34 such as SH-containing peptides, 35,36 proteins 37 and polymers. 38 They provide AuNCs with not only biocompatible shells and controllable surface charge to bind composite charged cargos to cross bio-barriers, but also multiple functional regions such as a tumor target domain and site-specic substrate to respond at a desired site by rational designing and regulating the proportion of ligands.…”
