New urine testing method holds promise for kidney stone sufferers

Despite being a key preventative measure for kidney stone patients, metabolic urine testing is underutilised due to the slow collection and turnaround times of existing methods.

This has prompted a research team led by biomedical and mechanical engineer Professor Pak Kin Kwong to develop a new biomimetic detection system, slippery liquid-infused porous surface (SLIPS)-LAB.

based on surfaces found in carnivorous nepenthes pitcher plants, the SLIPS surface enables samples to combine with the reagent to automatically combine at the required timed rate of reaction, eliminating the need for expensive machinery and trained technicians to perform tests.

The team claims the new test can be performed in clinics or even homes, at a fraction of the ...
