In the article Making precise structures at the smallest scale, the 3mE communication department explains how tiny structures, at the nano- and micro-scale, can be used for biomedical applications. ‘When such sensors are embedded in structures designed to hold cells and channel liquids, miniature laboratories are obtained (an approach called ‘organ-on-chip’) that are very attractive tools for biomedical and pharmaceutical research.’
Sasso thinks diabetes, wound healing and kidney stones are possible targets for his nanosensors.
The Nanoscribe, with its 20-nanometre pixel-size, completes the range of relevant dimensions. ‘We now have access to all relevant length scales, from 20 nanometer to the millimeter scale,’ Sasso said.
Instead of making each sensor pixel-by-pixel, Sasso studies replication techniques such as stamping a mold of the desired structures into soft polymer material.
