Unraveling the Role of Ligands Adsorption/Desorption on Photoluminescence Blinking in Single Water-Soluble InP-Based Quantum Dots.

Water-soluble quantum dots (QDs) face the challenges of photoluminescence (PL) blinking accompanied by photodegradation due to ligand desorption, which pose barriers to the implementation of QDs in their optical and optoelectronic applications. Here, we demonstrate the critical role of ligand adsorption/desorption dynamics in modulating PL blinking behaviors and photostability of water-soluble InP-based QDs at the single-dot level. Pre-adding excess ligands to water-soluble QDs can redirect ligand adsorption/desorption dynamics toward adsorption dominance and effectively passivate surface traps induced by dilution, converting PL blinking types from band-edge carrier blinking (BC-blinking) to Auger-blinking dominance.

EnsembleDesign: messenger RNA design minimizing ensemble free energy via probabilistic lattice parsing.

Motivation: The task of designing optimized messenger RNA (mRNA) sequences has received much attention in recent years, thanks to breakthroughs in mRNA vaccines during the COVID-19 pandemic. Because most previous work aimed to minimize the minimum free energy (MFE) of the mRNA in order to improve stability and protein expression, which only considers one particular structure per mRNA sequence, millions of alternative conformations in equilibrium are neglected. More importantly, we prefer an mRNA to populate multiple stable structures and be flexible among them during translation when the ribosome unwinds it.
