Una supercolla fatta per il 90% d'acqua è stata messa a punto negli Stati Uniti, dai ricercatori del Massachusetts Institute of Technology (MIT).
È un materiale trasparente chiamato idrogel, dalla consistenza simile a quella della gomma e può aderire a moltissimi tipi di superfici, dal vetro alla ceramica, all'alluminio.
Descritto sulla rivista Nature Materials, il nuovo prodotto dalle innumerevoli applicazioni ha la stessa efficacia dei collanti presenti in natura, in grado di tenere attaccati i tendini e la cartilagine alle ossa o, altro esempio, le conchiglie agli scogli. Stando agli scopritori, il prodotto è anche in grado di tenere insieme lo scheletro di robot di nuova concezione capaci di movimenti più fluidi.
