Making microscopic machines using metallic glass

May 22, 2012 – 10:00 pm

Making microscopic machines using metallic glass - Researchers in Ireland have developed a new technology using materials called bulk metallic glasses to produce high-precision molds for making tiny plastic components. The components, with detailed microscopically patterned surfaces could be used in the next generation of computer memory devices and microscale testing kits and chemical reactors.

Sensor pins and microneedles

February 29, 2012 – 1:04 pm

An array of electrochemical sensors embedded in microneedles could allow physicians and other healthcare practitioners to continuously monitor several chemical changes in patients over time, according to researchers in the US. Although chemical sensing is an essential part of modern healthcare, acquiring regular samples of body fluids remains a labor intensive and inconvenient process, and simple, real-time monitoring is somewhat lacking.

A cuticle new composite

February 27, 2012 – 11:03 pm

A new biomimetic material based on insect cuticle that is inexpensive to produce, biodegradable, and biocompatible could replace polymers in a range of medical applications and consumer products. The material was developed by researchers at the Wyss Institute for Biologically Inspired Engineering at Harvard University and reproduces the exceptional strength, toughness, and versatility of the biopolymer-based cuticle [J.G. Fernandez et al., Adv Mater (2011) doi: 10.1002/adma.201104051].
