The pharmaceutical field is seeing remarkable progress in drug delivery and synthesis methodologies. A novel nanoparticle system combining PLGA polymer with albumin exhibits ultrahigh colloidal stability and drug loading capacity, promising improved chemotherapy delivery with reduced side effects. Beta-blocker manufacturing is revolutionized through an amine-functionalized graphene oxide membrane nanoreactor achieving near-complete yield in seconds at room temperature. Additionally, newly developed peptide linkers in antibody-drug conjugates enhance stability and therapeutic safety. These innovations collectively aim to optimize drug efficacy, reduce toxicity, and streamline production processes in pharmaceutical engineering.
