HKBU invents novel cell sensor for rapid and low-cost screening of drug-resistant bacteria

Our team developed a novel cell sensor with a barcode-like micro-channel structure that enables rapid and low-cost screening of drug-resistant bacteria. The invention could potentially be used on a large-scale in resource-limited situations such as frequent safety screenings of water, food and public facilities, as well as urgent surveys of massive samples during an infectious disease outbreak, particularly in developing countries.

The test results of the “barcode” cell sensor were consistent with those conducted with conventional antimicrobial susceptibility testing (AST). The test can be completed in three hours, which is much faster than conventional AST that requires 16 to 24 hours for results.

This work has been published in Biosensors and Bioelectronics. More details about the publication are available at:

Our research team has filed a patent application for the invention, and they plan to develop it into a portable AST instrument. This work has been featured in the HKBU research news. Following is the link to the news release.
