WebJun 2, 2024 · Poly (β-amino ester)s (PBAEs) are a class of evolving non-viral vectors that have made significant advancements in the past 20 years. The class was first developed into linear PBAEs in 2000, but the development of this class transitioned to branched PBAEs in 2016 ( 22, 23 ). Webampicillin using branched biodegradable polymers has been described in this study. The conjugates have been prepared coupling the β-lactam antibiotic with branched polymer matrices based on the natural oligopeptide core. The cyto- and genotoxicity of the synthesized polymers were evaluated with a bacterial luminescence test, two protozoan
