Ultrasensitive Profiling of Metabolites Using Tyramine-Functionalized Graphene Quantum Dots
Graphene quantum dots (GQDs) are emerging fluorescence reporters attractive for optical sensing, owing to their high photostability, highly tunable photoluminescence, molecular size, atomically thin structure, biocompatibility, ...
Monitoring Dynamic Cellular Redox Homeostasis Using Fluorescence-Switchable Graphene Quantum Dots
Monitoring cellular redox homeostasis is critical to the understanding of many physiological functions ranging from immune reactions to metabolism, as well as to the understanding of pathological development ranging from ...
Polydopamine-Enabled Approach toward Tailored Plasmonic Nanogapped Nanoparticles: From Nanogap Engineering to Multifunctionality
We present a platform strategy that offers diverse flexibility in tailoring the structure and properties of core–shell plasmonic nanoparticles with built-in nanogaps. Our results have demonstrated that polydopamine serves ...
Activatable Photoacoustic Nanoprobes for In Vivo Ratiometric Imaging of Peroxynitrite
Organic semiconducting nanoprobes doped with bulky borane can undergo specific activation by ONOO− even at tumor-relevant acidic pH (6.8), permitting in vivo ratiometric photoacoustic imaging of ONOO− in the tumor environment ...
Controlling armchair and zigzag edges in oxidative cutting of graphene
Density-functional theory (DFT) calculations reveal that the formation of an armchair epoxy chain on a graphene sheet is energetically favorable when oxidation occurred on both sides of the graphene sheet. However, the ...
Multilayered semiconducting polymer nanoparticles with enhanced NIR fluorescence for molecular imaging in cells, zebrafish and mice
Although organic semiconducting polymer nanoparticles (SPNs) have emerged as an important category of optical imaging agents, their application in molecular imaging is still in its infancy and faces many challenges. We ...
