Functional coating metrology for materials science and biomedicine — biosensors, drug coatings and tissue scaffolds.

Focus Areas

Key process windows

Polymer films 50–500 nm — binding efficiency.

Biodegradable films 1–50 µm — release rate control.

Hydrogel 10–200 µm — cell infiltration & diffusion.

Metrology Table

Sub-scenario / Process	Film Layer	Thickness Range	Application & Metrology Value
Biosensor Surface Functionalization	Functionalized polymer film	50 nm – 500 nm	Affects biomolecule binding efficiency and sensor sensitivity; batch consistency
Controlled-Release Drug Coating	Biodegradable polymer drug-loaded film	1 µm – 50 µm	Governs drug release rate and duration; closed-loop coating uniformity
Tissue Engineering Scaffold	Hydrogel thin film	10 µm – 200 µm	Modulates cell infiltration depth and nutrient diffusion kinetics
