Application


  • Effect of Micelle-Incorporated Cisplatin With Sizes Ranging From 8 to 40 nm for the Therapy of Lewis Lung Carcinoma.: This research explores the use of micelle-incorporated cisplatin nanoparticles for cancer therapy, highlighting the significance of particle size on therapeutic efficacy. Poly-ʟ-glutamic acid sodium salt is used to improve drug delivery and target specificity (Wang Z et al., 2021).

  • Ternary Polypeptide Nanoparticles with Improved Encapsulation, Sustained Release, and Enhanced In Vitro Efficacy of Carfilzomib.: This paper describes the development of ternary polypeptide nanoparticles, including poly-ʟ-glutamic acid sodium salt, to enhance the encapsulation and release of carfilzomib, an anticancer drug. The study demonstrates improved drug efficacy and controlled release profiles (Agbana P et al., 2020).

  • Polymeric Core-Shell Nanoparticles Prepared by Spontaneous Emulsification Solvent Evaporation and Functionalized by the Layer-by-Layer Method.: This research focuses on the preparation of polymeric core-shell nanoparticles using a spontaneous emulsification method. Poly-ʟ-glutamic acid sodium salt is used to functionalize these nanoparticles, which can be applied in drug delivery systems (Szczęch M et al., 2020).

  • Co-administration of Combretastatin A4 Nanoparticles and Sorafenib for Systemic Therapy of Hepatocellular Carcinoma.: This study evaluates the combined use of combretastatin A4 nanoparticles and sorafenib for treating liver cancer. Poly-ʟ-glutamic acid sodium salt is employed to enhance the stability and delivery of these nanoparticles, showing promise in improving therapeutic outcomes (Wang Y et al., 2019).
