摘要
The infections caused by gram-positive bacteria (G+) is a major threat to public health due to their high morbidity and mortality, and the identification of G+ with high sensitivity and selectivity is urgently desirable. In this paper, a probe with aggregation-induced emission (AIE) characteristic is developed and used to discriminate G+ from other bacteria and fungus with excellent selectivity. Thanks for its AIE feature, this probe shows intense fluorescence when interacted with G+, and the signal can last for 24 h after incubating with S. aureus, which is benefit for long term tracing of translocation process with high contrast. Moreover, this probe can be used to visualize the infection processes of G+ towards mammalian cells, which provides valuable information for understanding the therapeutic mechanism.
