Un nou tip de bandaj „inteligent” a fost creat de cercetătorii din Marea Britanie. Acesta este impregnat cu nanocapsule cu antibiotice, activate de prezenţa în răni şi arsuri a bacteriilor, permiţând tratarea infecţiilor înainte ca acestea să se agraveze. Bandajul îşi schimbă culoarea pe măsură ce eliberează antibioticele în piele, alertându-i astfel pe medici de prezenţa infecţiei în acea zonă.
Bandajul se activează doar atunci când bacteriile agresive, cauzatoare de infecţii, produc anumite toxine care sparg nanocapsulele conţinând antibiotice şi coloranţi. În acest fel, antibioticele sunt eliberate doar când este nevoie, reducând astfel riscul deapariţie a unor bacterii rezistente la aceste medicamente.
Înainte de a fi comercializate, bandajele vor fi testate timp de trei ani.
