As a result of enhanced quantum confinement effects, nanoparticles act as artificial, man-made atoms with discrete electronic spectra that can be exploited as light sources for novel enhanced lasers, discrete components in nanoelectronics, qubits for quantum information processing and enhanced ultra-stable fluorescent labels for biosensors to detect, for example, cancers, malaria or other pathogens, and to do cell biology.

Nanoscience, the manipulation of matter at the atomic and molecular level, has produced nanomaterials so small their behavior and characteristics deviate from those of macroscopic specimens and maybe predicted by scaling laws or by quantum confinement effects.
