General description

两亲性嵌段共聚物（AmBC）由两种化学上不同的均聚物嵌段组成。嵌段之一是亲水的，另一个是疏水的。这些大分子溶于水介质时具有自组装的特性。PEG-PLGA是最常用于药物递送应用的可生物降解的两亲嵌段共聚物之一。PEG是亲水部分，PLGA是疏水部分。

Application

可用于合成靶向纳米粒子，从而用于差异递送和控释药物。

Features and Benefits

  • 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。

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 Nanoparticle Formation

AliAliphatic polyesters, including polylactide and polyglycolide, are biodegradable polymers widely used in medical applications.

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.

Whether reagents and samples need to be combined to achieve a desired reaction, or precise concentrations of solutions need to be mixed and delivered downstream, thorough mixing remains a critical step in many microfluidics-based biological and chemical assays and analyses.

Novel therapies are urgently needed for ovarian cancer, the deadliest gynecologic malignancy. Ovarian cancer has thus far been refractory to immunotherapies that stimulate the host immune system to recognize and kill cancer cells. This may be because of a suppressive
