Program Structure

Module 1: Fundamentals of Green Synthesis & Nanoparticle Design

• Why “green synthesis” in nanomedicine: cost, safety, solvent reduction, waste minimization.
• Nanoparticle basics: nucleation/growth, stabilization, aggregation, surface chemistry (conceptual).
• Key nanoparticle classes: Ag/Au, ZnO, TiO₂, Fe₃O₄, and polymer/biopolymer NPs (overview).
• Design constraints for biomedical use: purity, reproducibility, endotoxins (conceptual), and dose.

Module 2: Green Synthesis Pathways (Plants, Microbes, Biopolymers)

• Plant extract-mediated synthesis: phytochemicals as reducing and capping agents.
• Microbial synthesis: bacteria/fungi/algae routes (intracellular vs extracellular concepts).
• Biopolymer-assisted routes: chitosan, alginate, cellulose derivatives (intro).
• Choosing precursors, solvents, and stabilizers for safer formulations.

Module 3: Process Optimization & Reproducibility

• Critical parameters: pH, temperature, time, precursor concentration, extract ratio.
• Controlling size/morphology: how parameter shifts change outcomes.
• Batch-to-batch variation: standardizing extract prep and documenting protocols.
• Basic experimental design mindset for optimization (intro-level).

Module 4: Characterization Toolkit (What Each Technique Really Proves)

• UV–Vis: plasmon peaks and reaction tracking (interpretation-focused).
• DLS and zeta potential: size distribution, stability, and common pitfalls.
• FTIR: functional groups and evidence of capping/biomolecules.
• XRD: crystallinity and phase identification basics.
• SEM/TEM: morphology, core size vs hydrodynamic size—how to reconcile results.

Module 5: Formulation Stability & Surface Functionalization (Intro)

• Colloidal stability: aggregation, ionic strength, storage effects.
• Dispersion strategies and biocompatible stabilizers (conceptual).
• Surface modification basics: charge tuning, ligand concepts, polymer coatings.

Module 6: Biomedical Applications I — Antimicrobial, Wound Care & Coatings

• Mechanisms: ROS, membrane disruption, ion release (conceptual and evidence-based discussion).
• Assays overview: zone of inhibition, MIC/MBC concepts, biofilm basics.
• Wound dressings and hydrogels: integrating NPs into matrices (intro-level).
• Antimicrobial coatings for devices/surfaces: performance vs safety trade-offs.

Module 7: Biomedical Applications II — Drug Delivery, Imaging & Biosensing

• Drug delivery concepts: loading, release, targeting (intro-level; no clinical claims).
• Bioimaging basics: contrast mechanisms and nanoparticle selection rationale (conceptual).
• Biosensors: nanoparticle-enabled signal enhancement and surface functionalization (intro).
• Matching design parameters to application constraints (size, charge, stability, toxicity).

Module 8: Safety, Ethics, Translation & Avoiding Overclaims

• Biocompatibility basics: cytotoxicity, hemocompatibility, inflammation signals (conceptual).
• Toxicology factors: size, dose, surface chemistry, impurities, and biodistribution (intro).
• Quality and documentation: what makes “green-synthesized” claims credible.
• Responsible communication: limits of in vitro results and avoiding greenwash/health overclaims.

Final Project

• Design a green synthesis protocol for a chosen nanoparticle (e.g., AgNPs, AuNPs, ZnO, Fe₃O₄).
• Define optimization plan (parameters, controls, reproducibility checklist).
• Propose a characterization workflow and expected outputs.
• Map to one biomedical application with a realistic performance + safety rationale.
• Deliverables: project report + protocol sheet + characterization plan + application pitch (with limitations).
