• To explore the potential applications of these assemblies in affinity biosensing.

Main Methods:

• Review of established monolayer film preparation techniques: Langmuir-Blodgett (LB), self-assembly at liquid-solid interface, and Layer-by-layer (LBL) self-assembly.
• Analysis of how molecular composition within monolayers affects biomolecule activity.
• Focus on ordered assemblies formed by LB and self-assembly methods.

Main Results:

• Identified three primary methods for preparing monolayer films: LB, self-assembly, and LBL.
• Highlighted the influence of monolayer composition on biomolecule activity.
• Demonstrated the potential of ordered molecular assemblies in affinity biosensing.

Conclusions:
