제목 Dual Stimuli of β-Cyclodextrin/Paclitaxel Complexed Hyaluronic Acid for Photothermal and Chemotherapy Guided Bio-imaging system
초록 This study explored the use of carbonized fluorescent polydopamine(FNPs-pDA) core nanoparticles decorated with Hyaluronic acid (HA) conjugated Triphenylphosphonium (TPP) and boronic acid (BA)diol-linked β-cyclodextrin(β-CD), inclusion complexed with paclitaxel (PTX). The core FNPs-pDA allows fluorescent bioimaging and photothermal cytotoxicity activities, whereas the shell of the integrated structure regulates bio-direction for delivery of PTX to the tumor site. The carbonized FNPs-pDA was cross-linked with the boronic acid groups of HA-TPP-CD-PTX to promote the formation of boronate esters for pH-mediated photothermal activity, which have shown time dependent complete PTX release along with a photothermal mediated NIR response. In vitro dual bioimaging and photothermal-chemotherapeutic activities were compared between cancer and normal cells. Lysosomal escape and live/dead cells staining confocal images highlight the promise of this system.
