An injectable and self-healing nanocomposite hydrogel containing HAP and GO can achieve synergistic tumour proliferation inhibition and photothermal therapy.
Efficient synergistic therapeutic strategies for tumors with high specificity and sensitivity remain a major challenge. An injectable near-infrared (NIR)-responsive supramolecular hydrogel was prepared via host-guest interaction from conjugated poly(N-phenylglycine)- poly(ethylene...
In order to overcome the limitation of traditional therapies for cancer and improve the accuracy of treatment, more advantageous cancer treatment methods need to be explored and studied. As a result, photothermal photodynamic therapy of breast cancer using bovine serum albumin (BSA) modifies molybdenum disulfide nanoflakes. Then the well‐dispersed BSA‐MoS2 NFs are loaded in the injectable and self‐healing polysaccharide hydrogel which is prepared by the reaction of oxidized sodium alginate (OSA) and hydroxypropyl chitosan (HPCS) through the formation of Schiff base bonds. The injection and self‐healing properties of the nanocomposite hydrogel are investigated. In vitro photothermal and photodynamic investigations demonstrate that BSA‐MoS2 NFs possess obvious photothermal conversion and production of reactive oxygen species (ROS) under the irradiation of near infrared (NIR) laser (808 nm). In vivo anticancer investigation indicates that the nanocomposite hydrogel can be directly injected and remain in the tumor sites and achieve the synergistic photothermal‐photodynamic therapy of cancer.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
