Facile Synthesis, X-ray structure of new Multi-Substituted Aryl Imidazole ligand, Biological Screening and DNA binding of itsCr(III), Fe(III) and Cu(II) coordination compounds as potential antibiotic and anticancer drugs
A simple highly adjustable and effective synthesis of aryl imidazole ligand HL namely (2‐(1‐butyl‐4,5-diphenyl‐1H‐imidazol‐2‐yl)(4-bromophenol) was discussed where it was prepared by cyclo condensation of 5-Bromo-2-hydroxybenzaldehyde, benzil and Butan-1-amine. Three new Cr(III), Fe(III) and Cu(II) complexes of aryle imidazole ligand were synthesized. The multi-substituted aryl imidazole ligand (HL) and its complexes were characterized by using physicochemical and IR and electronic spectral ... Read more

2020 | Keywords Nanomaterials, Photo Catalysts,
Development of Nanomaterials as Photo Catalysts for Environmental Applications
Sustainability environmental lack is a growing and pivotal mater due to the issues: such as disturbances associated with biodiversity pollution, and climate change. Pollutants are the major cause of these environmental threats in the atmosphere. In recently, the nano-based photocatalyst is at the forefront of the author's interest because of its promising potential as a green chemical-based compound, high catalytic ... Read more

Opinion on Nanoparticles for Cancer Remediation

2020 | Keywords nanoparticles, Cancer Remediation,
Opinion on Nanoparticles for Cancer Remediation
Since the innovation of nanomedicine decades ago, significant advances have been made, especially with cancer as an objective. Nanoparticles in cancer remediation intends to cover different important aspects in this field including development of nanocarrier, delivery of gene, intrinsically active nanoparticles (NPs), microenvironment of tumor, toxicity, and immunology. The mostly applied biocompatible nanocarriers in clinical experiments are lipid, polymer, and ... Read more
