Abstract

We report a turn-on tetravalent sialic acid-coated tetraphenylethene luminogen (TPE4S) with excellent hydrophilicity, good stability, high sensitivity and unique selectivity towards sialidases, and the maximum fluorescence enhancement was ∼40 fold. More importantly, TPE4S was successfully utilized for the screening of sialidase inhibitors and diagnosis of bacterial vaginosis.
