Fluorescent Colloidal Nanomaterial Rapidly Internalized into Living Cells

Researchers have successfully incorporated colloidal nanoplatelets, a disc-like variation on spherical quantum dots, in a biological system. The new “lipoprotein nanoplatelets” were found to be rapidly internalized into living cells while retaining their fluorescence, making them uniquely valuable in live-cell imaging and labelling. Continue reading

Some Like it Hot: Simulating Single Particle Excitations

Understanding and manipulating plasmons is important for their potential use in photovoltaics, solar cell water splitting, and sunlight-induced fuel production from CO2. Now, for the first time, the interplay between the plasmon mode and the single particle excitation within a small metal cluster has been simulated directly. Read more at Berkeley Lab…my last embargo-held press release written while full-time at LBNL, despite the byline! Continue reading
