Biocorrosion behavior of biodegradable nanocomposite fibers coated layer-by-layer on AM50 magnesium implant
Published 2016“…The corrosion performance of coated and uncoated coupon samples was investigated by means of electrochemical measurements. The results showed that the AJS 3D membrane fiber layers, particularly the hybrid membrane layers containing a small amount of nHA (3wt.%), induce a higher biocorrosion resistance and effectively decrease the initial degradation rate compared with the neat AM50 coupon samples. …”

The Impact of Pamam Dendrimers on Her2-Positive Breast Cancer and the Early Stages of Embryogenesis
Published 2020“…PAMAMs exhibited significant anti-cancer effects that were more pronounced with cationic (-NH2) dendrimers, compared to neutral (-OH) or anionic (-COOH) and were greater in cationic G6 compared to cationic G4. Cationic G6 PAMAMs significantly decreased the viability of HER2-positive breast cancer cell lines down to 5.1% in SK-BR3 and to 5.7% in ZR-75 cells (p<0.001), in a dose and time-dependent fashion. …”
