Small Interfering RNA Nanoparticles Accelerate Wound Healing in Mouse Model

The time required for wound healing in a mouse model was significantly shortened by treatment with nanoparticles that had been loaded with small interfering RNA that blocked the synthesis of the enzyme fidgetin-like 2.  More...

Silica-Based Nanoparticles Selectively Kill Lung Cancer Cells

A novel approach to the selective delivery of toxic chemotherapeutic agents is based on nanoparticles that sequester the drug until it is liberated by the action of specific proteases that are present in a high concentration inside lung cancer cells.  More...
