Research output: Contribution to conferencePaperpeer-review


We demonstrate a novel stimuli-sensitive sensor working on the principle of the cleavage-induced fluorescent change via hydrophilicity control. In the design of molecular probe, labile groups cleavable under acidic condition were introduced as a model recognition site to explore the possible application of this system to the sensors detecting the presence of specific enzymes. Aiming at the biochip-based array detection, our fluorescent probe (Si-Py-Ac-PEG) was designed to comprise PEGylated pyrene with acid cleavable acetal spacer and to be tethered to the glass substrate.
