2. What are 2D structures? Submonolayer structures
Supported ultrathin films (<100 nm thickness)
Submonolayers
substrate
coating
Submonolayer structures
Ultrathin film – full coverage
Individual molecules
Patterned structures
Islands

3. Motivation: Why 2D structures?
Modelling aspect
- defined chemistry
- defined morphology
(2) Functional materials
- sensors
- transistors
- photonic devices
- receptors
- templates for nanomaterials
etc.

4. Our motivation: How 2D structures?
Cellulose / PS / gold nanoparticle films[1]
Cellulose / cellulose triacetate[2]
Plant-based materials form 2D structures but how?
