Nanosheets are ultra-thin, two-dimensional materials typically measuring only a few nanometers in thickness. They are derived from bulk materials, such as graphene, transition metal dichalcogenides, or oxides, and possess unique properties, including high surface area, electrical conductivity, and mechanical strength. Applications of nanosheets span various fields, including electronics (for transistors and sensors), energy storage (in batteries and supercapacitors), catalysis (as efficient catalysts), and biomedical devices (for drug delivery and imaging). Their unique characteristics enable advancements in material science, nanoelectronics, and sustainable technologies, making them pivotal in the development of next-generation products.
