Phys.org  July 7, 2022 The small aquatic snail-like mollusks use a tongue bristling with tiny, microscopic teeth to scrape food off rocks and into their mouths. These teeth contain a hard yet flexible composite, which in 2015 was found to be the strongest known biologically occurring material, far stronger than spider silk and comparable to man-made substances, including carbon fiber and Kevlar. An international team of researchers (UK, Poland USA – industry, Switzerland) has replicated the limpet tooth developmental processes ex vivo, where isolated limpet tissue and cells in culture generated new biomimetic structures. Transcriptomic analysis of each developmental stage […]
