Summary: This work presents a method to generate localized resistance gradient patterns using the properties of polypyrrole and wireless polarization triggered by bipolar electrochemistry. The reduction and overoxidation of polypyrrole result in highly resistive regions at predefined positions, allowing for the fine-tuning of the spatial distribution of the electrochemical modification. Energy-dispersive X-ray spectroscopy analysis confirms the localized physicochemical modifications. This approach offers the advantages of wireless bipolar electrochemistry and precise control over pattern formation compared to conventional methods.

Summary: This study focused on enhancing the anticancer effect of a novel dipeptide isolated from marine sponge-associated Bacillus pumilus AMK1 by formulating with Zinc oxide (ZnO) nanoparticles for the effective treatment against HepG2 liver cancer cells. The conjugated dipeptide with ZnO nanoparticles showed enhanced cytotoxicity against HepG2 liver cancer cells by inducing apoptosis, without any toxic effect on normal liver cells. Furthermore, embryotoxic studies in zebrafish embryos revealed that the conjugated dipeptide affected the development of zebrafish embryos only at relatively higher concentrations.
