一般描述

聚二甲基二烯丙基氯化铵(PDDA)是一种阳离子聚电解质,溶于水时易电离。这种聚合物可广泛用于废水处理(作为絮凝剂)和纳米颗粒的功能化修饰领域。

应用

聚二甲基二烯丙基氯化铵可作为稳定剂用于合成纳米颗粒,如封端的六氰基高铁酸铜(CuHCF)纳米颗粒。PDDA的加入可以防止颗粒聚集,并使我们可以合成具有可控尺寸和多分散性的纳米颗粒。 它也可用于制造化学和生物传感器。例如,PDDA 修饰的催化剂平台可用于L-半胱氨酸的电化学检测。

There is great clinical interest in developing novel nanocarriers for hydrophobic cyanine dyes used as photosensitizing agents in photodynamic therapy (PDT). In the present study we have employed nanoemulsion-templated oil-core multilayer nanocapsules as robust nanocarriers for a cyanine-type photosensitizer IR-786.

Compact and linearly growing polyelectrolyte multilayer films have been used to suppress desorption of drugs, nanoparticles or proteins from underlying polyelectrolyte multilayer films as well as to significantly change their mechanical properties. The polyelectrolyte based capping layers are however cumbersome

Recently, layer-by-layer (LbL) assembly has emerged as a versatile, gentle and, simple method for immobilization of functional molecules in an easily controllable thin film morphology.1,2 In this short review, we introduce recent advances in functional systems fabricated by using the mild, yet adaptable LbL technique.

We present an article that discusses two applications in particular; first, using these layers as polyelectrolyte membranes to control permeability.
