Research: Developing robust and sensitive 3D printed hydrogel sensors to quantify UV exposure, biological relevant analytes (lactate and glucose), or addressing environmental pollution problems by removing heavy metals ions using 3D printed hydrogel-basewd adsorbent tablets.

- Development of In-house nanomaterial-based bioinks for use in 3D printed multifunctional hydrogel-based sensors.

- Utilize computer-aided manufacturing and computer-aided design programs to rapidly prototype biosensors for sensing platforms.

- Development of a 3D printed hydrogel tablets based on polyethylenimine (PEI) used for heavy metal ion removal (e.g. Cu2+).

- 3D printed UV sensors incorporating TiO2 nanoparticles and organic dyes such as methyl orange, malachite green, and methylene blue.

- Development of a 3D printed colorimetric ozone sensor based on indigo carmine dye.

- Design 3D ceria based printed lactate and glucose biosensors incorporating lactate oxidase and glucose oxidase respectively.
