(2-/3-/4-NA). The catalyst showed robust recyclability, offering high conversions till the fifth cycle, with post-reaction XRD/TEM verifying the phase and morphological integrity. Biological assessments demonstrated favorable hemocompatibility, significant antioxidant activity, pro-angiogenic effects, and selective antiproliferative efficacy at appropriate concentrations, indicating a biocompatible interface suitable for biomedical applications. PdNPs@CS integrated the advantages of eco-friendly synthesis, efficient aqueous hydride-transfer catalysis, operational reusability, and promising biological applications, positioning this material as a multifunctional platform for water remediation and allied biomedical applications and aligning with contemporary biopolymer-engineered materials for sustainable pollutant mitigation and cycling stability.
