New pen-sized microscope could ID cancer cells in doctor's offices and operating rooms

Mechanical engineers have developed a handheld microscope to help doctors and dentists distinguish between healthy and cancerous cells in an office setting or operating room.

Utilizing nanotechnology for nitric oxide delivery in combating catheter-related microbial biofilms

A team of researchers has demonstrated that the release of nitric-oxide through a nanoparticle delivery system can be utilized as a therapeutic agent for the prevention and treatment of catheter-associated C. albicans biofilms infections.

Increasing oil's performance with crumpled graphene balls

Additive reduces friction and protects engines better than commercial lubricants.

Acoustic tweezers provide much needed pluck for 3D bioprinting

Researchers have demonstrated that acoustic tweezers can be used to non-invasively move and manipulate single cells along three dimensions, providing a promising new method for 3D bioprinting.

A targeted photosensitizer for cell manipulation

Scientists have re-engineered a fluorescent probe into a powerful optogenetic photosensitizer that can be used to manipulate cells.

'Nanotechnology: Super Small Science' - a suite of education and outreach activities

The National Science Foundation (NSF), in partnership with NBC Learn, has launched 'Nanotechnology: Super Small Science', a series of videos for middle and high school students.

New patent on fast measurements in liquids

A new invention will open the doors for an entirely new way of measuring properties within liquids. The invention, a sol-gel matrix, will make it possible to perform measurements that are reliable, incredibly rapid and can be conducted over extended periods of time.

Flexible and transparent pressure sensor

Healthcare practitioners may one day be able to physically screen for breast cancer using pressure-sensitive rubber gloves to detect tumors, owing to a transparent, bendable and sensitive pressure sensor newly developed by Japanese and American teams.

Scientists trigger and observe reactions in an individual molecule

Scientists have observed a fascinating molecular rearrangement reaction known as a Bergman cyclisation - which was first described in 1972 by American chemist Robert George Bergman.

Graphene composite may keep wings ice-free

A thin coating of graphene nanoribbons in epoxy has proven effective at melting ice on a helicopter blade.

Highly efficient heavy metal ions filter

Researchers have developed a new water filtration system that is superior to existing systems in many respects: it is extremely efficient at removing various toxic heavy metal ions and radioactive substances from water and can even be used in gold recovery.

Microscopic drug depots boost efficacy against tumors in animal model

Biomedical engineering researchers have developed a technique for creating microscopic 'depots' for trapping drugs inside cancer tumors. In an animal model, these drug depots were 10 times more effective at shrinking tumors than the use of the same drugs without the depots.

Mysterious behavior of quantum liquid elucidated, a world first

Researchers, through their precise measurement of current fluctuations in quantum liquids in an artificial atom created by nanotechnology, succeeded in elucidating theoretically-predicted behavior of quantum liquid in a non-equilibrium regime.
