This study, performed by CNR-ISM in collaboration with Università "La Sapienza" Roma, CNR-IC and CNR-IGAG, shows how ESD can confer the biosensor the ability to be stored at ambient pressure and temperature for long periods without compromising the enzymatic activity.
The fabricated biosensor shows a storage capability for up to 90 days, without any particular care under storage conditions, and a reuse performance for up to 24 measurements on both the electrode just prepared and on a three-months-old electrode. The absence of an entrapment matrix as well as any additional hazardous chemicals during the immobilization phase makes the process competitive in terms of environmental sustainability and toxicity.
Moreover, the application of a new electrospray deposition cycle on the used biosensors makes the biosensors work again with performances comparable to those of freshly made ones. This demonstrates that the technique is excellent for recycling and eliminates the waste of disposable device.
