“…Safavipour et al developed an aptasensor using a hybrid nanomaterial composed of TiO 2 nanotubes attached to GO via UV irradiation [ 138 ]. GCE was modified by such a hybrid nanomaterial with the subsequent immobilization of anti-MUC1 aptamers for the affinity capture of MCF-7 cells via surface-expressed MUC1 proteins.…”

“…GCE was modified by such a hybrid nanomaterial with the subsequent immobilization of anti-MUC1 aptamers for the affinity capture of MCF-7 cells via surface-expressed MUC1 proteins. An EIS-based device was able to ultrasensitively detect MCF-7 cells with LOD of 40 cells/mL within a linear concentration range from 10 3 to 10 7 cells/mL [ 138 ] (Approach 1).…”

This comprehensive review paper describes recent advances made in the field of electrochemical nanobiosensors for the detection of breast cancer (BC) biomarkers such as specific genes, microRNA, proteins, circulating tumor cells, BC cell lines, and exosomes or exosome-derived biomarkers. Besides the description of key functional characteristics of electrochemical nanobiosensors, the reader can find basic statistic information about BC incidence and mortality, breast pathology, and current clinically used BC biomarkers. The final part of the review is focused on challenges that need to be addressed in order to apply electrochemical nanobiosensors in a clinical practice.

Biosensors operating based on electrical methods are being accelerated toward rapid and efficient detection that improve the performance of the device. Continuous study in nano-and material-sciences has led to the inflection with properties of nanomaterials that fit the trend parallel to the biosensor evolution. Advancements in technology that focuses on nano-hybrid are being used to develop biosensors with better detection strategies. In this sense, titanium dioxide (TiO 2) nanomaterials have attracted extensive interest in the construction of electrical biosensors. The formation of TiO 2 nano-hybrid as an electrical transducing material has revealed good results with high performance. The modification of the sensing portion with a combination (nano-hybrid form) of nanomaterials has produced excellent sensors in terms of stability, reproducibility, and enhanced sensitivity. This review highlights recent research advancements with functional TiO 2 nano-hybrid materials, and their victorious story in the construction of electrical biosensors are discussed. Future research directions with commercialization of these devices and their extensive utilizations are also discussed.

“…Titanium dioxide (TiO 2 ) has been attracting scientific interests due to its spectacular activity on photodegrading contaminants from the environment. Its ability of photodecomposing pollutants, especially organic dyes such as rhodamine B, methylene blue, or crystal violet, has been ameliorated by modification in many sides: forms (nanoparticles to nanotubes [24,25] or nanowires [26]), composition (metals and metal oxide doping [27,28], organodoping [29]), and structure optimization [30]. TiO 2 nanotubes have been demonstrated possessing higher specific surface area, with an orderly one-dimensional structure, comparing with nanoparticles, providing great contribution to its photocatalytic activity.…”

In this work, silver nanoparticle- (AgNP-) embedded graphene oxide- (GO-) TiO2 nanotube (TNT) nanocomposite (labelled GAT) was successfully synthesized by gamma ray radiolysis. The influence of irradiation process, including one-step and two-step assistances and at different irradiation doses (5, 10, 15, 20, and 25 kGy), on the GAT’s physicochemical properties was achieved. Structure and properties of irradiated materials were analyzed by Fourier-transformed infrared (FT-IR), ultraviolet-visible absorption (UV-Vis), and Raman spectroscopies; X-ray diffraction (XRD); and scanning electron (SEM) and transmission electron (TEM) microscopies. In addition, selective scavengers of e-aq and ⋅OH radicals were used to investigate the radiolytic synthesis of GAT nanocomposite. It was revealed that gamma ray irradiation could strongly support the relation of the composite synthesis. Furthermore, the synthesized GAT nanocomposites showed a significant effect for Rhodamine B (RhB) photodecomposition after 60 minutes of natural sunlight exposure and evaluation by UV-Vis absorption spectroscopy. Briefly, the obtained results highlighted the potential of gamma irradiation as a “clean” and controllable way for synthesizing beneficial nanocomposite materials for wastewater purification and other environmental aspects.
