Nanoprinter produces 0.1-millimetre chair

With his new tool, the Nanoscribe, 3mE researcher Dr. Luigi Sasso has created a 0.1 mm-sized copy of the famous Rietveld chair. Sasso works on biomedical sensors which can be mass-produced.

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.
