Magnetically guided particles temporarily lower sperm count in mice

When it comes to contraceptives, men typically have to remember to use a condom, or get a difficult-to-reverse vasectomy. There may soon be a new option, however, in the form of injected particles that are magnetically guided to the testes.Continue Rea… Continue reading Magnetically guided particles temporarily lower sperm count in mice

Novel nanoparticles react to radiotherapy to kill cancer from within

Radiation therapy is currently one of the best treatments we have against cancer, but it could benefit from being more targeted to spare healthy cells. Now, researchers in Japan have developed nanoparticles that can penetrate tumors and kill them from … Continue reading Novel nanoparticles react to radiotherapy to kill cancer from within

Nanoparticle urine test diagnoses cancer and pinpoints its location

The earlier cancer is detected, the better the outcome for the patient. Now, researchers at MIT have developed a new diagnostic system that can be performed as a simple urine test to detect the presence of cancer, and if a positive is returned, a follo… Continue reading Nanoparticle urine test diagnoses cancer and pinpoints its location

European food safety panel reclassifies common food coloring as unsafe

The European Food Safety Authority (EFSA) has reclassified food coloring E171 (titanium dioxide) after an expert panel concluded it “can no longer be considered safe as a food additive.” The announcement comes after years of research suggesting the add… Continue reading European food safety panel reclassifies common food coloring as unsafe

Experimental oral pills auto-release insulin when glucose levels are high

Daily injections of insulin are a hassle for the hundreds of millions of people with diabetes. An oral pill would be much easier to swallow (pun intended), and now researchers from New York University Abu Dhabi have developed a new method for packing i… Continue reading Experimental oral pills auto-release insulin when glucose levels are high

Under-skin sensor uses bits of gold to show bloodstream drug levels

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.Continue ReadingCatego… Continue reading Under-skin sensor uses bits of gold to show bloodstream drug levels

Color blindness-correcting contacts inspired by antique glass

While there already 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 now developing a new type of corrective contact lens – and it was inspired by old go… Continue reading Color blindness-correcting contacts inspired by antique glass

Ultrasound and magnetism let drug-delivery nanobeads travel upstream

Although various groups are already working on nanoparticles that could be used for directed drug delivery via the bloodstream, most of those particles are designed to “go with the flow.” Now, however, Swiss researchers have created ones that can actua… Continue reading Ultrasound and magnetism let drug-delivery nanobeads travel upstream

Injections of drug-loaded sticky nanoparticles could shrink skin cancer

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.Continue ReadingCatego… Continue reading Injections of drug-loaded sticky nanoparticles could shrink skin cancer

“Super-hard” metals forged in new nanoparticle manufacturing process

Researchers at Brown University have developed a new way to make super-hard metals. The team made nanoparticle “building blocks” that could be fused together under moderate pressure, thanks to a chemical treatment.Continue ReadingCategory: Materials, S… Continue reading “Super-hard” metals forged in new nanoparticle manufacturing process
