摘要
In recent years, photothermal therapy (PTT), a new type of therapy, has been gradually recognized as a rapidly developing technology, and many nanomaterials have been applied to PTT. One of the representative nanomaterials in this field is nanoscale silver sulfide with rising significance in biomedicine like cell imaging. However, there are not much researches on the use of silver sulfide nanomaterials in photothermal therapy. Thus, a novel core-shell nanostructure was fabricated by encapsulating a hollow silver sulfide (HAg2S) core with a zeolite imidazole acid skeleton (ZIF-8), which is a representative metal-organic framework (MOF) crystal, for the purpose of carrying doxorubicin hydrochloride (DOX). The as-prepared HAg2S/ZIF-8 core-shell nanostructure can be targeted by hyaluronic acid (HA) molecules that are able to bind with CD44 receptors over-expressed on a variety of cancer cells, thereby implementing synergistic photothermal effect and chemotherapeutic effect in near-infrared (NIR) region in association with multiple responses to pH, HA, and NIR as well as DOX release. In summary, the present approach could help to inject fresh vitality into the future cancer cure.
