Drug delivery system

We are focusing on multifunctional stimuli-responsive carbon dot-based systems for specific controllable targeting delivery of anticancer drugs (paclitaxel, doxorubicin, etc.) or therapeutic agents (photothermal agents, nitride oxide, etc.). By employing multiple responsive modified carbon dots such as pH, temperature, redox, etc., the release of drugs after injection can be controlled at desired tumor site with sustained release.


we aim to develop bacterial probes or cancer detection platforms which are activable in specific disease conditions for both identification via colorimetric assay or electrochemical behavior and simultaneously perform killing activity via theranostic agents.


Hydrogels are three-dimensional, hydrophilic, polymeric networks capable of absorbing large amounts of water or biological fluids. Mostly, the hydrogel consist of amphiphilic nature which made it possible to tuning the matrix or inner structure of a hydrogel improving the stimulus responsiveness, which in turn affects physical properties and water uptake capacity. In our research study, we applied the mechanics of functionalized carbon dots (CD)-loaded hydrogel for 3 different applications, such as actuator, shape-memory, and self-healing.
