The polymer with ketone mercaptan as the fragment can form the shell of the nanocore, and simultaneously contain the polyorubicin and light sensitive compounds to achieve dual roles. Ketothiol polymers can also be used directly as drug carriers to contain paclitaxel ROS responsive groups, often in combination with a variety of methods. ROS, as the connecting part, connects the hydrophilic part and the hydrophobic part of the nanocarrier. When the nanocarrier encounters ROS, it breaks and releases drugs: the ROS responsive group can also act as the part connecting drug molecules and nanocarriers to release drugs under oxidation. Common ROS responsive groups generally contain sulfur, boron and tellurium. In addition, in order to inactivate the protein, ROS responsive groups can also be used to block the active center of the protein. Common ROS responsive genes include: polypropylene sulfide, borate, thione, tellurium, selenium, ferrocene, anthocyanins, etc.
