Building tailor-made DNA nanotubes step by step

Researchers at McGill University have developed a new, low-cost method to build DNA nanotubes block by block - a breakthrough that could help pave the way for scaffolds made from DNA strands to be used in ...

New nanogel for drug delivery

Scientists are interested in using gels to deliver drugs because they can be molded into specific shapes and designed to release their payload over a specified time period. However, current versions aren't ...

Potential toxicity of cellulose nanocrystals examined

Novel nanomaterials derived from cellulose have many promising industrial applications, are biobased and biodegradable, and can be produced at relatively low cost. Their potential toxicity—whether ingested, ...

Golden vehicle for drug delivery has hidden costs

One of the biggest ideas in treating disease involves material so small it isn't even visible. Miniscule gold particles – the size of several atoms – are being touted as vehicles to send drugs exactly ...

Voltage tester for beating cardiac cells

For the first time, scientists have succeeded in recording the current in membrane channels of contracting cardiac cells. To do this, the scientists combined an atomic force microscope with a widely used ...

DNA 'cage' could improve nanopore technology

Despite having a diameter tens of thousands of times smaller than a human hair, nanopores could be the next big thing in DNA sequencing. By zipping DNA molecules through these tiny holes, scientists hope ...

Nano-antioxidants prove their potential

Injectable nanoparticles that could protect an injured person from further damage due to oxidative stress have proven to be astoundingly effective in tests to study their mechanism.

Nanovectors combine cancer imaging and therapy

Researchers at Imperial College London and the Laboratoire de chimie de la matière condensée de Paris (CNRS/Collège de France/UPMC) have designed and developed hybrid gold-silica nanoparticles, which are ...

An end to the medicine dropper for eye injuries?

For years, treating scratches and burns to the eyes has usually involved dropping medicine onto the eyes several times a day, sometimes for weeks—a treatment that lends itself to missed doses and other ...
