“…[ 23,25,51,52 ] Doped TiO 2 is a typical success story. Researchers have successfully prepared TiO 2 doped with anions such as C [ 53,54 ] and N, [ 55 ] as well as TiO 2 doped with metal cations such as Fe, [ 56 ] V, [ 57 ] W, [ 58 ] Mn, [ 59 ] and rare earth metals. [ 60 ] Although both anion doping and cation doping could reduce the bandgap of TiO 2 , the specific effects were different.…”

With the promotion of nanochemistry research, large numbers of nanomaterials have been applied in vivo to produce desirable cytotoxic substances in response to endogenous or exogenous stimuli for achieving disease‐specific therapy. However, the performance of nanomaterials is a critical issue that is difficult to improve and optimize under biological conditions. Defect‐engineered nanoparticles have become the most researched hot materials in biomedical applications recently due to their excellent physicochemical properties, such as optical properties and redox reaction capabilities. Importantly, the properties of nanomaterials can be easily adjusted by regulating the type and concentration of defects in the nanoparticles without requiring other complex designs. Therefore, this tutorial review focuses on biomedical defect engineering and briefly discusses defect classification, introduction strategies, and characterization techniques. Several representative defective nanomaterials are especially discussed in order to reveal the relationship between defects and properties. A series of disease treatment strategies based on defective engineered nanomaterials are summarized. By summarizing the design and application of defective engineered nanomaterials, a simple but effective methodology is provided for researchers to design and improve the therapeutic effects of nanomaterial‐based therapeutic platforms from a materials science perspective.

“…In the biomedical field of TiO 2 nanomaterials, only in 2023 were two important reviews published in the domain of drug delivery systems for cancer therapy, prevention, and treatment of infections, implants [211], as well as cancer diagnosis and its therapeutic systems [158]. In cancer treatment as well as in epilepsy, TiO 2 NPs must be inserted directly into the diseased organ, so they must have appropriate shapes, like whiskers [215], hollow nanoparticles [216], pyramids [217], and rhombic [218]. A suitable/appropriate geometry leads to better incorporation of biomolecules into the sensor network, which facilitates the interaction between TiO 2 molecules and biomarkers [219].…”

For many years, TiO2-based materials and improving their properties in order to expand their application areas have been the focus of numerous research groups. Various innovative approaches have been proposed to improve the photocatalytic and gas-sensing properties of TiO2 nanostructures. In this review, we aim to synthesize the available information in the literature, paying special attention to the sol–gel technology, which is one of the most frequently used methods for TiO2 synthesis. The influence of dopants on the structural, morphological, optical, and electrical properties of TiO2 and the way to modify them in a controlled manner are briefly discussed. The role of shallow and/or deep energy levels within the TiO2 bandgap in the electron transport behavior of doped TiO2 is emphasized. Selected research on photocatalytic applications in water disinfection, wastewater treatment, and self-sterilizing coatings that contribute to improving the quality of human life and environmental preservation is highlighted. A survey of biosensors that are closely related to medical applications such as cancer detection, implantology, and osteogenesis is also provided. Finally, the pressing problems that need to be solved in view of the future development of TiO2-based nanostructures are listed.

“…To enhance PDT effect, it is crucial to synthesize excellent PS, improve their solubility in aqueous mediums, and respond to the near-infrared region (NIR) range for deep tissue penetration [ 219 ]. Importantly, materials that can absorb light energy in the NIR region exhibited promising potential in PTT and related imagining [ 220 , 221 ].…”
