Scheme 1

The scheme of hydrogel platform (IR820/Mgel) preparation and its applications for preventing post-surgical tumor recurrence and improving breast reconstruction. The IR820/Mgel helps forward IR820, as a photothermal agent retention in tumor site, thus presents an excellent photothemal performance for preventing locally recurrence of cancer. In addition, the hydrogel platform as a filler could repair the breast defects, at the same time porous MPs offer a well support for cells attachment and anchorage, which may provide benefits for breast reconstruction
