Abstract The conversion of cisplatin Pt(II) into a Pt(IV) complex is strategy that can be used to overcome resistance and side effects, this involves the functionalization axial positions cisplatin. Using ligands with bioactivity target specific cancer cell species could lead targeted treatment mitigate severe effects. Furthermore, enhanced cellular uptake resistance. Anchoring “dual-acting” prodrug in self-assembled hybrid porous metal-organic frameworks (MOFs) has revealed an even more...

Controlling the premature release of hydrophobic drugs like quercetin over physiological conditions remains a challenge motivating development smart and responsive drug carriers in recent years. This present work reported surface modification mesoporous silica nanoparticles (MSN) by functional compound having both amines (as positively charged group) carboxylic (negatively group), namely 4-((2-aminoethyl)amino)-4-oxobut-2-enoic acid (AmEA) prepared via simple mechanochemistry approach. The...

In response to global clean energy demands, this study develops mixed matrix membranes (MMMs) for gas separation in renewable applications. MMMs are produced through phase inversion by employing polysulfone and bimetallic-ZIF (Ni-Co-ZIF-67). Bimetallic-ZIF, formed in-situ Co Ni metals water solvent with triethylamine, enhances selectivity. 4 wt% bimetallic-ZIF, Co: ratio of 9:1 (4Ni10Z67), exhibit remarkable selectivity: CO2/CH4 (21.19), H2/N2 (1.47), H2/CH4 (44.82), N2/CH4 (30.40). Strong...
