title: Functionalized thermoresponsive micelles self-assembled from biotin-PEG-b-P(NIPAAm-co-HMAAm)-b-PMMA for tumor cell target.
abstract: Novel micelles, comprising hydrophilic PEG shells, hydrophobic PMMA cores, and thermosensitive P(NIPAAm-co-HMAAm) segments were self-assembled from the biotin-PEG-b-P(NIPAAm-co-HMAAm)-b-PMMA triblock copolymer. The thermosensitive micelles exhibited superior stability and showed thermotriggered drug release behavior upon temperature alterations. The fluorescence spectroscopy and confocal microscopy studies confirmed that the self-assembled biotinylated micelles can be specifically and efficiently bonded to cancer cells with the administration of biotin-transferrin, suggesting that the multifunctional micelles have great potential as drug carriers for tumor targeting chemotherapy.
