Engineered fabrication of EGCG-UV absorber conjugated nano-assemblies for antioxidative sunscreens with broad-band absorption

Biocompatible, bacteria-targeting resveratrol nanoparticles fabricated by Mannich molecular condensation for accelerating infected wound healing

“…11,12 Currently, most of these carriers have been designed to enhance the killing effect toward cancer cells, [13][14][15] and the concentration of polyphenol compounds determines the antioxidant and anti-inflammatory properties of polyphenols. [16][17][18][19][20][21] A low concentration of Res plays roles in ROS clearance and inflammation inhibition, whereas a high concentration of Res would promote oxidative stress. Thus, for speeding up the wound healing it is necessary to improve its biocompatibility while maintaining its anti-inflammatory and antioxidant properties.…”

Functional Nanoparticles Encapsulated in Resveratrol-Formaldehyde Resin for Cancer Therapy

“…The remained signal at 9.53 ppm (A) indicated the retention of active hydroxyl groups, while the disappearance of the signal at 9.18 ppm (B) was assigned to the deprotonation transition. , The disappearance of the signal at 6.12 ppm (H) and the decrease of the signals at 6.75 ppm (F) and 6.37 ppm (G) confirmed that F, G, and H had higher reactive activities during polymerization. And the appearance of the signals at 4.72, 4.56, 3.85, 1.24, 1.06, and 0.85 ppm identified the newly formed methylene bridges (Ar–CH 2 –Ar) (3.85 ppm), Ar–C–OH (4.72 and 4.56 ppm), and the methyl groups and methine groups of the main chain carbon bridge (1.24, 1.06, and 0.85 ppm), respectively. − By combining FTIR and 1 H NMR results, it was proposed that the substitution sites for the reaction are F, G, and H. Namely, the bioactive para-hydroxyl sites of resveratrol were preserved. The elemental analysis of Res NPs showed the C/H/O/N ratios of 11.4:10.8:2.4:1.…”
