Tiny Capsule Effectively Kills Cancer Cells

Scientists create nanoscale vehicle to battle cancer without harming healthy cells

A tiny capsule invented at a UCLA lab could go a long way toward improving cancer treatment.
Devising a method for more precise and less invasive treatment of cancer tumors, a team led by researchers from the UCLA Henry Samueli School of Engineering and Applied Science has developed a degradable nanoscale shell to carry proteins to cancer cells and stunt the growth of tumors without damaging healthy cells.

In a new study, published online Feb. 1 in the peer-reviewed journal Nano Today, a group led by Yi Tang, a professor of chemical and biomolecular engineering and a member of the California NanoSystems Institute at UCLA, reports developing tiny shells composed of a water-soluble polymer that safely deliver a protein complex to the nucleus of cancer cells to induce their death. The shells, which at about 100 nanometers are roughly half the size of the smallest bacterium, degrade harmlessly in non-cancerous cells. (more…)
