Scientists discover fat-blocking effect of nanofibers

Tiny balls of nano-sized cellulose fibres added to food reduced fat absorption by up to half in laboratory and animal experiments, report scientists from Nanyang Technological University, Singapore (NTU Singapore) and Harvard ...

New nanoparticles help detect deep-tissue cancers

Researchers have developed a new form of nanoparticle and associated imaging technique that can detect multiple disease biomarkers, including those for breast cancer, found in deep-tissue in the body.

Dental plaque is no match for catalytic nanoparticles

Combine a diet high in sugar with poor oral hygiene habits and dental cavities, or caries, will likely result. The sugar triggers the formation of an acidic biofilm, known as plaque, on the teeth, eroding the surface. Early ...

Nanoparticles improve tumor treatment in mice

In the treatment of cancer, chemotherapy is a cleaver, not a scalpel. By attacking rapidly dividing cells, chemotherapy effectively fights tumors, but it also ravages healthy cells in the gut, bone marrow, the scalp and other ...

Targeting headaches and tumors with nano-submarines

Scientists at the Mainz University Medical Center and the Max Planck Institute for Polymer Research (MPI-P) have developed a new method to enable miniature drug-filled nanocarriers to dock on to immune cells, which in turn ...

A safe and effective way to whiten teeth

In the age of Instagram and Snapchat, everyone wants to have perfect pearly whites. To get a brighter smile, consumers can opt for over the counter teeth-whitening treatments or a trip to the dentist to have their teeth bleached ...

X-ray triggered nano-bubbles to target cancer

Innovative drug filled nano-bubbles, able to be successfully triggered in the body by X-rays, have been developed by researchers, paving the way for a new range of cancer treatments for patients.

Brain function partly replicated by nanomaterials

The brain requires surprisingly little energy to adapt to the environment to learn, make ambiguous recognitions, have high recognition ability and intelligence, and perform complex information processing.
