Optical Properties: The absorption and emission spectra of quantum dots can be tuned by changing their size, a property useful in display technology and biological imaging. Electrical Properties: The bandgap of semiconductor nanomaterials like silicon nanowires changes with size, impacting their conductivity and making them suitable for nanoelectronics. Chemical Properties: The reactivity of nanomaterials can be altered due to the increased surface area to volume ratio and the quantum confined effect, enhancing their use in catalysis.
