MIT News: Fast, cheap nanomanufacturing Arrays of tiny conical tips that eject ionized materials could fabricate nanoscale devices cheaply.

October 4th, 2014

Luis Fernando Velásquez-García’s group at MIT’s Microsystems Technology Laboratories (MTL) develops dense arrays of microscopic cones that harness electrostatic forces to eject streams of ions. The technology has a range of promising applications: depositing or etching features onto nanoscale mechanical devices; spinning out nanofibers for use in water filters, body armor, and “smart” textiles; or

ILP Institute Insider: Mass Spectrometry in Your Hand Electrospray arrays can dramatically downsize systems and costs for onsite chemical analysis — and many other applications.

September 1st, 2014

If you’re out in the field doing environmental testing, food checks, forensic work or other chemical analysis, mass spectrometry is an extremely accurate detection tool with one huge drawback: You can lose days in sending samples back to the lab for analysis. MIT researchers now have developed technologies that promise to enable mass spectrometers that

MIT News: A leap forward in X‑ray technology Lightweight, portable device could provide detailed images — even of soft tissue

December 5th, 2013

X-rays transformed medicine a century ago by providing a noninvasive way to detect internal structures in the body. Still, they have limitations: X-rays cannot image the body’s soft tissues, except with the use of contrast-enhancing agents that must be swallowed or injected, and their resolution is limited. But a new approach developed by researchers at MIT

MIT News: Spin Doctors – Luis Velásquez‑García and team develop a cost‑effective way to spin nanoscale fibers

November 20th, 2012

Nanofibers — strands of material only a couple hundred nanometers in diameter — have a huge range of possible applications: scaffolds for bioengineered organs, ultrafine air and water filters, and lightweight Kevlar body armor, to name just a few. But so far, the expense of producing them has consigned them to a few high-end, niche

How to corner the MEMS market

April 19th, 2012

In the last decade, MEMS (microelectromechanical devices) have wrought revolutions in several industries: Arrays of micromirrors, for instance, enabled digital film projectors, and accelerometers like those in Nintendo’s Wii controller have changed gaming. But commercially successful MEMS represent a tiny sampling of the prototypes developed in academic and industry labs, — from supersensitive biological sensors to
