Nanostructures, as a physical system, are materials or assemblies characterized by at least one spatial dimension in the nanometer range (typically 1–100 nm), where quantum confinement, high surface-to-volume ratio, and size-dependent effects dominate their physical behavior. They include zero-, one-, two-, and three-dimensional architectures such as quantum dots, nanowires, nanotubes, and nanoporous frameworks. In this size regime, electronic, optical, mechanical, and thermal properties deviate markedly from bulk counterparts, enabling tunable band gaps, altered phonon and electron transport, and enhanced catalytic activity. Nanostructures are central platforms in nanophotonics, nanoelectronics, energy conversion, and sensing, where controlled synthesis, morphology, and interface engineering critically determine system performance.
Bacteria are a major cause of infections and death in hospital settings, due—in part—to the rising incidence of antibiotic resistance. In the United States, antibiotic-resistant bacteria are involved in more than 2 million ...
