Versatile Langmuir-Blodgett platforms for layered structures: Precise engineering, structure complexity and...

Langmuir-Blodgett (LB) technology excels in assembling nanomaterials into precise layered structures, yet challenges in solvent requirements and scalability limit its broader application. This review systematically analyzes recent advancements in LB methodologies-from solvent engineering to innovative transfer techniques-that enable the fabrication of complex architectures with enhanced optoelectronic, catalytic, and biomimetic properties for applications in sensing, energy storage, and interfacial science. We critically examine its dual role in improving intrinsic material performance and serving as a versatile platform for synthesizing functional systems. Looking forward, we outline key development paths, including heteroassembly, integration with non-equilibrium systems, and advanced biomimetic membranes. These directions, capitalizing on LB's core strengths in molecular-level precision and macroscopic force-directed nanoarchitectonics, are poised to drive innovations in next-generation nanomaterials and devices.
