摘要:
Binding an analyte can cause a change in fluorescence emission of a sensor. The change in fluorescence can be related to the amount of analyte present. The sensor can include a semiconductor nanocrystal linked to a fluorescent moiety. Upon excitation, the fluorescent moiety can transfer energy to the semiconductor nanocrystal, or vice versa.
摘要:
Water soluble InAs(ZnCdS) semiconductor nanocrystals with bright and stable emission in the near infrared (NIR) wavelength range have been prepared. The NIR semiconductor nanocrystals can be functionalized to enable imaging of specific cellular proteins. In addition, the utility of the NIR region for in vivo biological imaging is clearly demonstrated by the superior ability of InAs(ZnCdS) semiconductor nanocrystals to image tumor vasculature.

摘要:
An electro-optical device can include a plurality of semiconductor nanocrystals. In some circumstances, the device can omit an electron transporting layer.
摘要:
A semiconductor nanocrystal can have a barbell shape. The nanocrystal can include two semiconductor materials selected so that upon excitation, one charge carrier is substantially confined to the one semiconductor material and the other charge carrier is substantially confined to the other semiconductor material.
