Abstract Photodynamic therapy (PDT) for hypoxic tumors has attracted wide attention owing to its noninvasiveness, easy maneuverability, and instantaneity. However, hypoxia in penetration depth of conventional ultraviolet light greatly weakened performance. To solve these problems, under NIR-II irradiation, squaric acid nanoparticles (SQ NPs) with superior reactive oxygen, especially, hydroxyl r...

Objective (s): SN38 is the prominent and effective anticancer drug for treating various types of human cancers such as colorectal, ovarian and lung cancers. SN38 is highly toxic, and due to its poor solubility in aqueous media, and low stability and hydrolysis at physiological pH, it has not been used as an anti-cancer drug. To overcome these problems, SN38 was conjugated with new nanocarriers ...
