Nanoparticles

An oral pill would be much easier for diabetics than daily insulin injections. An experimental new method for packing insulin into capsules helps it survive the trip through the stomach to the bloodstream, and releases its payload only when needed.

When a patient is receiving medication, it can be difficult to determine how much of the drug is actually making its way into their bloodstream. A new subdermal "tattoo" could help, thanks to its color-changing gold nanoparticles.

While there are glasses that help compensate for red-green color blindness, the lenses often can't be shaped to users' prescriptions. That's why scientists are developing a new type of corrective contact lens, inspired by old gold-containing glass.

Although various groups are working on nanoparticles that could be used for directed drug delivery via the bloodstream, most of those particles are made to "go with the flow." Now, however, researchers have created ones that can travel upstream.

Researchers at Yale University have shown how skin cancer could one day be treated with a simple injection. The team found that they could shrink tumors by injecting them with adhesive nanoparticles loaded with chemotherapy drugs.

Researchers at Brown University have developed a new way to make super-hard metals, up to four times harder than usual. The team made nanoparticle “building blocks” that could be fused together under pressure, thanks to a chemical treatment.

We have seen how gold nanoparticles can fight cancer in a number of ways, but they aren’t without their problems. Scientists in Japan have found a solution to one of these drawbacks, through the careful addition of a ring-shaped synthetic compound.

Osteoarthritis is a painful and fairly common condition that’s hard to slow, so treatment options are mostly limited to reducing pain. But a new study in mice has now found that nanotherapeutic injections into the knee can slow cartilage degradation.

A new study led by researchers from University College London suggests that combining traditional chemotherapy with an experimental therapy that uses magnetic nanoparticles to heat tumor cells could significantly enhance the efficacy of both treatments.

Ordinarily, epoxies are cured by exposure to either heat or ultraviolet light. Both have their drawbacks, which are nicely avoided by a new epoxy that hardens when passed through a magnetic field to produce a similar bond using a fraction of the energy.

Killing cancer cells isn’t too hard – the tricky part is doing so without harming healthy cells. Now researchers have developed nanoparticles that selectively release drugs inside tumors, while keeping them safely locked away when in healthy cells.

Pesticides may indeed kill plant pathogens, but they're also harmful to the environment. Newly developed nanoparticles may provide a more eco-friendly alternative, as they boost the immune systems of crop plants, then harmlessly dissolve.
