🔎 What Are Polymer Nanoparticles?

Polymer nanoparticles are nanocarriers (10–1000 nm) composed of synthetic or natural polymers. Their versatility makes them ideal for:

Application	Purpose
Targeted Drug Delivery	Direct drugs to specific tissues/cells
Controlled Release	Release over time to maintain efficacy
Vaccine Delivery	Deliver antigens/adjuvants precisely
Cancer Therapy	Minimize off-target toxicity

⚗️ Step-by-Step Synthesis Process

🔹 Step 1: Polymer Selection

Polymer	Features	Applications
PLGA	Biodegradable, tunable release	Long-acting injections
PEG	“Stealth” properties, hydrophilic	Systemic delivery
Chitosan	Cationic, mucoadhesive	Intranasal, oral, mucosal routes

We help select the optimal polymer based on solubility, drug compatibility, and route of administration.

🔹 Step 2: Drug Incorporation Techniques

Methods We Use:

• Emulsion–Solvent Evaporation
• Nanoprecipitation
• Spray Drying

Technique	Best For
Nanoprecipitation	Small molecules, fast screening
Emulsion-based	Hydrophobic drugs, slow release
Spray drying	Scale-up, powder formulations
