Tuning light to kill deep cancer tumors

An international group of scientists led by Gang Han, PhD, at the University of Massachusetts Medical School, has combined a new type of nanoparticle with an FDA-approved photodynamic therapy to effectively kill deep-set ...

Light-based therapy weakens antibiotic-resistant bacteria

Antibiotics are standard treatments for fighting dangerous bacterial infections. Yet the number of bacteria developing a resistance to antibiotics is increasing. Researchers from Texas A&M University and the University of ...

Radical new treatment system lights up cancer therapy

One approach to treating cancer is photodynamic therapy using photo-uncaging systems, in which light is used to activate a cancer-fighting agent in situ at the tumor. However, suitable agents must be stable under visible ...

Toward a nanomedicine for brain cancer

In an advance toward better treatments for the most serious form of brain cancer, scientists in Illinois are reporting development of the first nanoparticles that seek out and destroy brain cancer cells without damaging nearby ...

A 3-D light switch for the brain

A new tool for neuroscientists delivers a thousand pinpricks of light to a chunk of gray matter smaller than a sugar cube. The new fiber-optic device, created by biologists and engineers at the Massachusetts Institute of ...

Higher energies for laser-accelerated particles possible

The use of compact laser accelerators for cancer therapy with charged particles such as protons could become possible in the future if scientists succeed in generating protons with very high energies.

Adult stem cells transform faster with two lasers

Stem cell therapy requires a lot of human cells of a specific type. Shining a near-infrared laser on adult stem cells derived from human body fat makes the stem cells replicate 54% faster. Following that up with a green laser ...
