What is it about?
A highly sensitive, selective, and low-cost sensing probe is developed by a simple one-step laser-scribing process of plastic waste. A flexible point-of-care device is developed as a prototype and shows a highly specific response to dopamine in human urine samples.

A new path to upcycling plastic waste. Sensing the neurotransmitter in humans noninvasively
Perspectives
Thanks to the success of this simple but efficient laser-scribing method, which is capable of altering the matrix's electronic and chemical composition, various types of flexible and tunable biosensors made from plastic waste are now possible.
