Titanium dioxide (TiO2) is a kind of wide-bandgap semiconductor. Nano-TiO2 devices exhibit size-dependent and novel photoelectric performance due to their quantum limiting effect, high absorption coefficient, high surface-volume ratio, adjustable band gap, etc. Due to their excellent electronic performance, abundant presence, and high cost performance, they are widely used in various application fields such as memory, sensors, and photodiodes. This article provides an overview of the most recent developments in the application of nanostructured TiO2-based optoelectronic devices. Various complex devices are considered, such as sensors, photodetectors, light-emitting diodes (LEDs), storage applications, and field-effect transistors (FETs). This review of recent discoveries in TiO2-based optoelectronic devices, along with summary reviews and predictions, has important implications for the development of transitional metal oxides in optoelectronic applications for researchers.

“…To this end, various forms of nanostructured titania can be used, such as nanoparticles, nanotube arrays, and nanosheets, as recently reviewed [224]. Zinc-doped titania nanoparticles have been also proposed to develop glutamate sensors, as glutamate is a common food additive but also a useful biomarker, since abnormal levels were linked to pathologies such as epilepsy, Alzheimer's and Parkinson's diseases, ischemia, and amyotrophic lateral sclerosis [225].…”

Nanostructured titania (TiO2) is the most widely applied semiconducting oxide for a variety of purposes, and it is found in many commercial products. The vast majority of uses rely on its photo-activity, which, upon light irradiation, results in excited states that can be used for diverse applications. These range from catalysis, especially for energy or environmental remediation, to medicine—in particular, to attain antimicrobial surfaces and coatings for titanium implants. Clearly, the properties of titania are enhanced when working at the nanoscale, thanks to the increasingly active surface area. Nanomorphology plays a key role in the determination of the materials’ final properties. In particular, the nucleation and growth of nanosized titania onto carbon nanostructures as a support is a hot topic of investigation, as the nanocarbons not only provide structural stability but also display the ability of electronic communication with the titania, leading to enhanced photoelectronic properties of the final materials. In this concise review, we present the latest progress pertinent to the use of nanocarbons as templates to tailor nanostructured titania, and we briefly review the most promising applications and future trends of this field.

The significance of glutamic acid in healthcare as a neurotransmitter and food additive has prompted the scientific community to develop cost-effective non-enzymatic sensors with improved sensitivity, selectivity, and stability. Herein, we propose a non-enzymatic electrochemical sensor based on low-cost transition metal hydroxides to detect glutamic acid efficiently. An n-butanol/ water interface-assisted synthesis strategy was employed as an initial step to tailor two-dimensional nickel hydroxide nanoflakes. To further improve electrical conductivity, nickel hydroxide nanoflakes were composited with a small amount of highly conductive multiwalled carbon nanotubes to form NH/MWCNT composite. The NH/MWCNT composite-modified sensor demonstrated excellent detection of glutamic acid with a detection limit of 72 nM, even in the presence of many interfering groups. The practicality of the sensor in medical technology was established by its ability to detect glutamic acid released by SH-SY5Y neural cells in both normal and oxygen−glucose deprivation-stressed conditions. As an extended application, the proposed sensor was also demonstrated to detect monosodium glutamate, a food additive found in commercially available food products. Finally, as a proof of concept, an in-house flexible sensor was fabricated to monitor glutamic acid released by human neural cells and monosodium glutamate in food samples. We anticipate that the present work will contribute to the development of cutting-edge third-generation non-enzymatic sensors for glutamic acid monitoring.
