New Hope for Lipophilic Silicon Nanoparticles in Biology

Size separated lipophilic silicon nanoparticles that fluoresce from red to infrared are encapsulated into liposomes and delivered to cells. Specific particles are found to encapsulate better into the liposomes and thus enhance cellular uptake and toxicity when delivered to cancer … Continue reading
