In this study, the adsorption of doxorubicin (DOX), an anticancer drug, on pristine graphene (PG) and oxide (GO) nanocarriers with different surface oxygen densities in aqueous environment varying pH levels was investigated using molecular dynamics (MD) simulation. The drug loading release GO nanocarrier also simulated as controller mechanism. Overall, DOX/nanocarrier interactions become stronger density increases. Although has a negligible effect single-molecule surfaces under acidic...
Abstract Since their emergence in 2014, graphitic carbon nitride quantum dots (g‐C 3 N 4 QDs) have attracted much interest from the scientific community due to distinctive physicochemical features, including structural, morphological, electrochemical, and optoelectronic properties. Owing desirable characteristics, such as non‐zero band gap, ability be chemically functionalized or doped, possessing tunable properties, outstanding dispersibility different media, biocompatibility, g‐C QDs shown...

As a glycerol-based polyester, poly(glycerol azelaic acid) (PGAz) has shown great potential for biomedical applications, such as tissue engineering. However, it tends to show low mechanical strength and relatively fast biodegradation rate, limiting its capability of mimicking supporting broad range hard tissues bone. Moreover, the typical thermal curing process poly(glycerol-co-diacids) is one their drawbacks. To overcome these limitations, glycidyl methacrylate (GMA) moieties were first...

Hierarchical bridge nanoscale...
Reactive molecular dynamics simulation was employed to compare the damage mitigation efficacy of pristine and polyimide (PI)-grafted polyoctahedral silsesquioxane (POSS), graphene (Gr), carbon nanotubes (CNTs) in a PI matrix exposed atomic oxygen (AO) bombardment. The concentration POSS orientation Gr CNT nanoparticles were further investigated. Overall, mass loss, erosion yield, surface damage, AO penetration depth, temperature evolution are lower for systems with randomly oriented CNTs or...
