In aquo ppm level detection of acrylamide through S-to-N acyl transfer mediated activation of pro-sensors†
Abstract
Water-soluble pro-sensors for acryl compounds including acrylamide (AM) were developed. Spontaneous conversion to active thiolate (Ph-S and Nap-S) occurs through pH-increase. While Ph-S forms flat nano-tapes with AM, Nap-S acted as a turn-on fluorescence detector, sensing AM up to the ppm level.
