LbL deposition offers several significant advantages: - Precision: It allows for the precise control of film thickness at the nanometer scale. - Versatility: A wide range of materials, including polymers, proteins, and nanoparticles, can be used. - Uniformity: The method produces uniform and defect-free films. - Customizability: The optical, electrical, and mechanical properties of the films can be tailored by selecting appropriate materials and deposition parameters.
