    摘要: Systems and methods of detecting force on the nanoscale including methods for detecting force using a tetrapod nanocrystal by exposing the tetrapod nanocrystal to light, which produces a luminescent response by the tetrapod nanocrystal. The method continues with detecting a difference in the luminescent response by the tetrapod nanocrystal relative to a base luminescent response that indicates a force between a first and second medium or stresses or strains experienced within a material. Such systems and methods find use with biological systems to measure forces in biological events or interactions.

    摘要: The present invention provides a photovoltaic device. In an exemplary embodiment, the photovoltaic device includes a substrate having a thin film disposed thereon, where the thin film includes alloyed ternary nanocrystals. The present invention provides also provides a method of making ternary compound nanocrystals. In an exemplary embodiment, the method includes (1) degassing a solution of PbO, oleic acid and 1-octadecene (ODE) in a container, (2) heating the solution in the container, (3) injecting a first mixture of trioctylphosphine (TOP):Se solution, TMS2S, diphenylphosphine (DPP) and ODE into the heated solution, thereby forming a second mixture in the container, (4) adding ODE to the second mixture in the container, (5) growing the nanocrystals in the second mixture in a reaction in the container, and (6)_quenching the reaction, thereby resulting in precipitated nanocrystals in the container. In a further embodiment, the present invention further includes purifying the precipitated nanocrystals.
