Cellular Uptake of mAuNPs
Shown in Figure 2A are photographs taken under dark field microscope of B16-F10 cells cultured with and without mAuNPs for 24 h. Numerous small spots in B16-F10 cells co-cultured with mAuNPs for 24 h were visible compared to controls, indicating that mAuNPs entered B16-F10 cells. Next, we investigated the cellular uptake of mAuNPs after B16-F10 cells were co-cultured with mAuNPs at different concentrations by ICP-AES (Figure 2B). The amount of cellular uptake of mAuNPs increased with the AuNPs co-culture concentrations in the range of ~0–60 μg/mL. The cellular uptake amount reached 3.6 pg/cell at the co-culture concentration of 10 μg/mL. If the weight of 10

Researchers have recently extracted the proton mass radius from the experimental data.
A research group at the Institute of Modern Physics (IMP) of the Chinese Academy of Sciences (CAS) presented an analysis of the proton mass radius in
Physical Review D on May 11. The proton mass radius is determined to be 0.67 ± 0.03 femtometers, which is obviously smaller than the charge radius of the proton.
In the Standard Model, the proton is a composite particle made of quarks and gluons and it has a non-zero size. The radius of the proton is a global and fundamental property of the proton. It is related to the color confinement radius a property governed by quantum chromodynamics (QCD).
