Tracking lung macrophages

A new technique will allow researchers to track subsets of immune cells that patrol and defend the lungs, to better understand the roles of these cells during lung inflammation, infection and injury.

Better adenoma detection

Fluorescent nanoparticles clearly identified colonic adenomas — precursors to colorectal cancer — in mice, and the formulation should translate to clinical use in humans.

Nanobeacon lights up colon tumors

A novel fluorescent nanobeacon can distinguish normal from diseased colon tissue, potentially offering advantages for colorectal cancer screening.
