Titanium dioxide (TiO2) is one of the most abundantly used nanomaterials for human life. It is used in sunscreen, photovoltaic devices, biomedical applications and as a food additive and environmental scavenger. Nano-TiO2 in biomedical applications is well documented. It is used in endoprosthetic implants and early theranostics of neoplastic and non-neoplastic maladies as a photodynamic therapeutic agent and as vehicles in nano-drug delivery systems. Herein, we focus on the recent advancements and applications of nano-TiO2 in bio-nanotechnology, nanomedicine and photodynamic therapy (PDT).

“…Cancer cells reduced the platinum metal {Pt (IV)} salts to metallic nanoclusters although the mechanism of this effect is still unknown. Chen et al designed a rapid one-step synthesis of fluorescent nanoclusters of platinum by the collaborative reduction of glutathione and ascorbic acid with chloroplatinic acid as a precursor [ 80 ]. They have also reported the spontaneous synthesis of biocompatible platinum nanoclusters by cancerous cells, which can be helpful in PTT and imaging.…”

Nanotechnology has enabled the development of many alternative anti-cancer approaches, such as thermal therapies, which cause minimal damage to healthy cells. Current challenges in cancer treatment are the identification of the diseased area and its efficient treatment without generating many side effects. Image-guided therapies can be a useful tool to diagnose and treat the diseased tissue and they offer therapy and imaging using a single nanostructure. The present review mainly focuses on recent advances in the field of thermal therapy and imaging integrated with multifunctional inorganic nanoparticles. The main heating sources for heat-induced therapies are the surface plasmon resonance (SPR) in the near infrared region and alternating magnetic fields (AMFs). The different families of inorganic nanoparticles employed for SPR- and AMF-based thermal therapies and imaging are described. Furthermore, inorganic nanomaterials developed for multimodal therapies with different and multi-imaging modalities are presented in detail. Finally, relevant clinical perspectives and the future scope of inorganic nanoparticles in image-guided therapies are discussed.

“…For example, MALDI mass spectrometry and ESI mass spectrometry have been used to evaluate the products of hydrophobic metal cluster synthesis; however, in both cases, the resulting mass spectrum is comparatively simple. 23,24,29,3235,39,43,46,49,50,5356,5963,6567,72,74,76,120122,126130,132,133,135137,147150,152,155,158160,162164,170,171,174180,182,183,202,203,216,219223,225,227,231,235,236,238,239,250252,254,260,262,263,275,276,278,286,287,291294,…”
