一般說明

嵌段共聚物胶束广泛用于药物递送领域。PEG-PDLLA是一种可生物降解的聚合物胶束，可用作疏水性药物（如紫杉醇）的载体。PEG是亲水性部分，PDLLA是疏水性部分，后者形成负载疏水性药物的胶束核心。

應用

用作控制和靶向释放疏水性抗癌药物的载体。
药物的水溶性

特點和優勢

  • 良好的生物相容性、低免疫原性和良好的降解性。
  • 通过改变嵌段共聚物链段的尺寸可以轻松调节其性能，以适合特定应用。

This work describes the synthesis and characterization of novel thermoresponsive highly branched polyamidoamine-polyethylene glycol-poly(D,L-lactide) (PAMAM-PEG-PDLLA) core-shell nanoparticles. A series of dendritic PEG-PDLLA nanoparticles were synthesized through conjugation of PEG of various chain lengths (1500, 6000 and 12,000 g mol(-1)) to

It is generally assumed that polymeric micelles, upon administration into the blood stream, carry drug molecules until they are taken up into cells followed by intracellular release. The current work revisits this conventional wisdom. The study using dual-labeled micelles containing

Electrospun Nanofibers for Drug Delivery Systems

Local delivery of bioactive molecules using an implantable device can decrease the amount of drug dose required as well as non-target site toxicities compared to oral or systemic drug administration.

Biodegradable Polyester-based Nanoparticle Formation by Miniemulsion Technique

Aliphatic polyesters such as polylactide, poly(lactide-co-glycolide) and polycaprolactone, as well as their copolymers, represent a diverse family of synthetic biodegradable polymers that have been widely explored for medical uses and are commercially available.

Polymersomes for Drug Delivery

The development of drugs that target specific locations within the human body remains one of the greatest challenges in biomedicine today.
