Bacteriophages Enter Bacteria Using an Iron Tipped Spike

Fri, 02 Mar 2012 13:36:14 +0000

Bacteria-Killing Viruses Wield an Iron Spike Forget needles in haystacks. Try finding the tip of a needle in a virus. Scientists have long known that a group of viruses called bacteriophages have a knack for infiltrating bacteria and that some … Continue reading

NASA Biocapsules Deliver Medical Interventions Based Upon What They Detect in the Body

Fri, 10 Feb 2012 10:31:54 +0000

Very cool innovation from NASA. The biocapsule monitors the environment (the body it is in) and responds with medical help. Basically it is acting very much like your body, which does exactly that: monitors and then responds based on what … Continue reading

MIT Engineers Design New Type of Nanoparticle for Vacines

Tue, 22 Feb 2011 23:44:12 +0000

MIT engineers have designed a new type of nanoparticle that could safely and effectively deliver vaccines for diseases such as HIV and malaria. The new particles, described in the Feb. 20 issue of Nature Materials, consist of concentric fatty spheres … Continue reading

Atomic Force Microscopy Image of a Molecule

Fri, 28 Aug 2009 12:30:10 +0000

The delicate inner structure of a pentacene molecule imaged with an atomic force microscope. For the first time, scientists achieved a resolution that revealed the chemical structure of a molecule. The hexagonal shapes of the five carbon rings in the … Continue reading

Nanoparticles With Scorpion Venom Slow Cancer Spread

Wed, 22 Apr 2009 14:36:39 +0000

In a, chlorotoxin molecules, colored blue and green, attach themselves to a central nanoparticle. In b, each nanoprobe offers many chlorotoxin molecules that can simultaneously latch on to many MMP-2s, depicted here in yellow, which are thought to help tumor … Continue reading

Harnessing Light to Drive Nanomachines

Thu, 04 Dec 2008 23:45:29 +0000

A team led by researchers has shown that the force of light indeed can be harnessed to drive machines – when the process is scaled to nano-proportions. Their work opens the door to a new class of semiconductor devices that … Continue reading

Carbon Nanotechnology in an 17th Century Damascus Sword

Wed, 01 Oct 2008 12:32:03 +0000

Carbon nanotechnology in an 17th century Damascus sword Wootz, with its especially high carbon content of about 1.5%, should have been useless for sword-making. Nonetheless, the resulting sabres showed a seemingly impossible combination of hardness and malleability. … Amazingly, they … Continue reading

Fri, 27 Jun 2008 14:55:30 +0000

The Lemelson-MIT Prize awards $500,000 to mid-career inventors dedicated to improving our world through technological invention and innovation. Joseph M. DeSimone received the 2008 award. His exposure to polymer science led him to pursue a Ph.D. in chemistry from Virginia … Continue reading

Gecko-inspired Bandage

Fri, 25 Apr 2008 22:31:12 +0000

MIT creates gecko-inspired bandage Drawing on some of the principles that make gecko feet unique, the surface of the bandage has the same kind of nanoscale hills and valleys that allow the lizards to cling to walls and ceilings. Layered … Continue reading
