Webster's research has examined the multiple uses of nanotechnology. His studies focus on the development, production, and assessment of nanophase materials as superior biomedical materials. He has researched on the application of nanophase materials for tissue regeneration. His research has focussed on hydroxyapatite, the major inorganic component to bone. In contrast to hydroxyapatite that had not been doped, Webster's research on osteoblast (bone-forming cells) response to hydroxyapatite doped with divalent and trivalent cations showed that osteoblast adherence and differentiation on the doped HA were increased. In other research, he creates surfaces with nanostructures that have been FDA-approved for implantation in tissues like bone, the spine, and dental applications.
His research has included nanoparticles that may enter biofilms, lessen inflammation, and specifically target cancer cells. Dr. Webster was the first to identify improved tissue growth on nanomaterials. He was the first to identify decreased bacteria functions on nanomaterials. Dr. Webster was the first to establish a mathematical equation that can be used to predict nanoscale surface features to improve tissue growth, reduce infection, and limit infection. He trademarked this process as "Nano-Optimized", 2008.
Webster has obtained many patents for his inventions and his patents including:

Retractions
As of September 1, 2024, at least seven articles co-authored by Webster have been retracted.
Dai, Mingzhi; Wu, Zhendong; Qi, Shaocheng; Huo, Changhe; Zhang, Qiang; Zhang, Xingye; Webster, Thomas J.; Zhang, Hengbo (2020-03-17). "Implementation of PPI with Nano Amorphous Oxide Semiconductor Devices for Medical Applications". International Journal of Nanomedicine. 15: 1863–1870. doi:10.2147/IJN.S207852. PMC7085341. PMID32231432. (Retracted,see doi:10.2147/IJN.S354565,PMID34992366) - "Concerns were raised by the Editor following the authors request to make several corrections to the published article. Many of the requested corrections related to data descriptions in the Materials and Methods and the Results and Discussion. Readers should note the Editor confirms the retraction is not due to academic misconduct but owing to the number of corrections reported within the article which were too numerous to be corrected in a standard corrigendum."
Webster resigned from his position at Northeastern in 2021, reportedly "after dozens of his studies came under scrutiny online." Webster later stated, "An external investigation panel appointed by Northeastern University consisting of world renowned researchers came to the conclusion in their final report that I had not fabricated or falsified data, and subsequently cleared me of any academic wrongdoing."
