半导体聚合物作为功能有机高分子材料被广泛应用于有机光电子器件领域的研究。近年来由半导体聚合物构成的荧光纳米粒子引起了广泛的研究兴趣。这类新型纳米探针具有光学吸收截面大、量子效率高、辐射跃迁速率快、光稳定性好等特性
在荧光成像和生物传感等领域获得了重要应用。本文简要概述了近年来半导体聚合物纳米粒子的研究进展

In recent years
fluorescent semiconducting polymer nanoparticles
which primarily consist of -conjugated polymers
have been attracted considerable attention in an extensive range of applications
such as fluorescence imaging and biosensing. These -conjugated polymer nanoparticles are called polymer dots (Pdots) when they have particle size comparable to that of the inorganic quantum dots. Pdots have many charming properties
such as large absorption cross section
high fluorescence quantum yield
very fast emission rates
excellent photostability
and so on. In this review
we briefly summarize recent findings of the photophysical properties of Pdots
the surface functionalization and biomolecular conjugation of Pdots and their applications in cellular labeling
in vivo
imaging
biosensing
single-particle tracking
drug delivery and photodynamic therapy.
