Abstract
Photothermal therapy has been renowned for its non-invasive and highly precise approach in cancer treatment. Therefore, the synthesis of suitable photothermal agent has attracted wide attention. In this study, a non-covalent method for modifying carbon nanotube by hyaluronic acid based azo polymer was proposed. Hyaluronic acid based azo polymer was attached to the surface of carbon nanotube via the π-π interaction and hydrophobic interaction between azo moiety and the wall of carbon nanotube. After the self-assembly process, the modification was demonstrated with transmission electron microscopy, infrared spectra and thermal gravimetric analysis. The modified carbon nanotube (HA-MWCNT) was endowed with both the tumor cell targeting property of hyaluronic acid and the excellent photothermal effect of carbon nanotube, enabling it to serve as photothermal agent for eliminating tumor cells. Upon co-culture with HeLa cells, HA-MWCNT was proved to exhibit low cytotoxicity without irradiation. After being irradiated with infrared laser light, the HeLa cells cultured with HA-MWCNT perished due to the heat generated by the endocytosed HA-MWCNT, which attested to the potential of HA-MWCNT as a photothermal agent for cancer treatment.
期刊介绍:
Chinese Journal of Polymer Science (CJPS) is a monthly journal published in English and sponsored by the Chinese Chemical Society and the Institute of Chemistry, Chinese Academy of Sciences. CJPS is edited by a distinguished Editorial Board headed by Professor Qi-Feng Zhou and supported by an International Advisory Board in which many famous active polymer scientists all over the world are included. The journal was first published in 1983 under the title Polymer Communications and has the current name since 1985.
CJPS is a peer-reviewed journal dedicated to the timely publication of original research ideas and results in the field of polymer science. The issues may carry regular papers, rapid communications and notes as well as feature articles. As a leading polymer journal in China published in English, CJPS reflects the new achievements obtained in various laboratories of China, CJPS also includes papers submitted by scientists of different countries and regions outside of China, reflecting the international nature of the journal.
