Sugar-coated nanoworms for better cancer detection

Nanoparticles could aid diagnosis and treatment of diseases including cancer... if the immune system would leave them alone. A new study shows that inducing crosslinks on nanoparticle surface sugars lets them escape mouse immune system and identifies remaining culprit for human immune recognition of nanoparticles.

Researchers build nanoscale autonomous walking machine from DNA

Researchers have developed a nanoscale machine made of DNA that can randomly walk in any direction across bumpy surfaces. Future applications of such a DNA walker might include a cancer detector that could roam the human body searching for cancerous cells and tagging them for medical imaging or drug targeting.
