“…Briey, 5 mL of the AgNC@DNA solution were deposited on amino-propyl-silatrane (APS) modied mica for a total of 2 min. 19,20,36 Excess sample was washed with DI water and gently dried under a ow of high purity argon gas and under vacuum overnight. AFM images in air were then recorded with a 1.5 Hz scanning rate using TESPA-300 probes from Bruker Nano, Inc.…”

“…AFM imaging could be challenging method for unexperienced researchers due to specic surface chemistry required for reliable deposition of AgNC@DNA. 36 Other alternative methods to assess heterogeneity of the samples might be considered, such as reversedphase high-performance liquid chromatography (HPLC), 37 gel electrophoresis, 38 or Transmission Electron Microscopy (TEM). 39 2.6 Energy-dispersive X-ray spectroscopy (EDS) analysis AgNC@hpC 12 solutions prepared as described above were diluted to 50 mM aer ltration.…”

Silver nanoclusters (AgNCs) are the next-generation nanomaterials representing supra-atomic structures where silver atoms are organized in a particular geometry. DNA can effectively template and stabilize these novel fluorescent AgNCs. Only...

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
