The diagram shows how the new hydrogel microfluidic chip can be used to carry out a quick antimicrobial susceptibility test. This could lead to reduced antibiotic resistance.
Hydrogel microfluidic chips
Researchers from the Department of Chemistry of HKBU have invented the world’s first multidimensional antimicrobial susceptibility testing (AST) system. The new technology can provide information about drug resistant pathogens present in patients, enabling doctors to accurately determine the effectiveness and appropriate dosage of antibiotics needed for effective treatment. 
 
 
 
The new fully-automated system is 10-20 times faster, more accurate and can also be run at a much lower cost than the current AST methods which are only available in professional medical laboratories. It is expected that the invention will aid diagnosis by providing doctors with a precise prescription which will significantly reduce the chance of antibiotic abuse or misuse. The team is planning to commercialise the system so that more people can benefit from the development.
