Novel Alginate-Gelatin Hybrid Nanoparticle for Drug Delivery and Tissue Engineering Applications

الملخص EN

Novel alginate-gelatin hybrid nanoparticles were fabricated using single oil in water (O/W) emulsification techniques.

Physicochemical property of the particle was characterized using scanning electron microscopy and Fourier’s transmission infrared spectroscopy.

Particle size was determined using zeta potential metastasize analyzer and was found to be in range of 400–600 nm.

AGNPs were used for culturing human keratinocytes for two weeks to check biocompatibility of synthesized AGNPs.

3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay showed increased metabolic activity of cells cultured on AGNPs in comparison to two-dimensional (2D) system (control).

Cellular attachment on nanoparticle was further confirmed using SEM and 4′,6-diamidino-2-phenylindole staining.

The drug release profile shows possible electrostatic bond between alginate and gelatin resulting in controlled release of drug from AGNPs.

For the first time alginate-gelatin hybrid nanosystem has been fabricated and all results showed it can be used as potential system for delivery of drug and therapeutical agents to cells and can also be used for regenerative medicine applications.
