Biodegradable nanoparticles designed for drug delivery: The number of nanoparti...
Mendes, Lívia Palmerston; Delgado, Jorge; Costa, Ângela Daniela Alves; Vieira, Marcelo Sousa; Benfica, Poliana Lopes; Lima, ElianaNanostructured drug delivery systems are based on biocompatible and biodegradable components. Composition, size and membrane surface properties are characteristics that may influence cell viability in cytotoxicity assays. In this work, four nanostructured systems commonly used for drug delivery were prepared and cytotoxicity was evaluated on human lymphocytes and Balb/c 3T3 fibroblasts. The hemolytic potential ...
Avaliação da citotoxicidade de diferentes nanotransportadores sem substância at...
