WebJul 21, 2024 · Optical trapping of sub−micrometer particles in three dimensions has been attracting increasing attention in a wide variety of fields such as physics, chemistry, and biologics. Optical fibers that allow stable trapping of such particles are not readily available but beneficial in system integration and miniaturization. Here, we present a readily … WebTosylate is a good leaving group so it could lead to SN2 or SN1 type chemistry (I think azide can also displace tosylate by SNAr type reactions). So the reaction mechanism will … inspirational community quotes
