The use of carbon nanotubes (CNTs), which are nanometric materials, in pathogen detection, protection of environments, food safety, and in the diagnosis and treatment of diseases, as efficient drug delivery systems, is relevant for the improvement and advancement of pharmacological profiles of many molecules employed in therapeutics and in tissue bioengineering. It has contributed to the advancement of science due to the development of new tools and devices in the field of medicine. CNTs have versatile mechanical, physical, and chemical properties, in addition to their great potential for association with other materials to contribute to applications in different fields of medicine. As, for example, photothermal therapy, due to the ability to convert infrared light into heat, in tissue engineering, due to the mechanical resistance, flexibility, elasticity, and low density, in addition to many other possible applications, and as biomarkers, where the electronic and optics properties enable the transduction of their signals. This review aims to describe the state of the art and the perspectives and challenges of applying CNTs in the medical field. A systematic search was carried out in the indexes Medline, Lilacs, SciELO, and Web of Science using the descriptors "carbon nanotubes", "tissue regeneration", "electrical interface (biosensors and chemical sensors)", "photosensitizers", "photothermal", "drug delivery", "biocompatibility" and "nanotechnology", and "Prodrug design" and appropriately grouped. The literature reviewed showed great applicability, but more studies are needed regarding the biocompatibility of CNTs. The data obtained point to the need for standardized studies on the applications and interactions of these nanostructures with biological systems.

“…The flavone baicalein was electrochemically detected in the Chinese herb Oroxylum indicum, as well as in human urine samples, using a GCE modified by bismuth oxidecarboxylated MWCNTs that showed an LOD of 2.0 nM in the linear range from 0.01 to 15 µM [85]. Baicalein in the Chinese medicine Scutellaria baicalensis Georgi was quantified using a GCE modified with MoO 3 and poly (3,4-ethylenedioxythiophene) (PEDOT) NWs nanocomposites, with the sensor showing an LOD of 1.5 nM in the linear range from 0.005 to 0.86 µM [86].…”

Flavonoids represent a large group of aromatic amino acids that are extensively disseminated in plants. More than six thousand different flavonoids have been isolated and identified. They are important components of the human diet, presenting a broad spectrum of health benefits, including antibacterial, antiviral, antimicrobial, antineoplastic, anti-mutagenic, anti-inflammatory, anti-allergic, immunomodulatory, vasodilatory and cardioprotective properties. They are now considered indispensable compounds in the healthcare, food, pharmaceutical, cosmetic and biotechnology industries. All flavonoids are electroactive, and a relationship between their electron-transfer properties and radical-scavenging activity has been highlighted. This review seeks to provide a comprehensive overview concerning the electron-transfer reactions in flavonoids, from the point of view of their in-vitro antioxidant mode of action. Flavonoid redox behavior is related to the oxidation of the phenolic hydroxy groups present in their structures. The fundamental principles concerning the redox behavior of flavonoids will be described, and the phenol moiety oxidation pathways and the effect of substituents and experimental conditions on flavonoid electrochemical behavior will be discussed. The final sections will focus on the electroanalysis of flavonoids in natural products and their identification in highly complex matrixes, such as fruits, vegetables, beverages, food supplements, pharmaceutical compounds and human body fluids, relevant for food quality control, nutrition, and healthcare research.

TiO2 nanotube arrays (TNTA) were prepared by anodization, and then bismuth oxide (Bi2O3) was deposited on TNTA by vacuum impregnation‐chemical precipitation method to prepare Bi2O3@TNTA composite electrodes, which were used to detect 4‐nitrophenol (4‐NP) as an electrochemical (EC) sensor. The effects of the Bi2O3 loading amount and the pH value of the detection solution on the detection performance were exhaustively studied. Under best conditions, the linear range is 5 μΜ–30 mM, the sensitivity is 0.6696 μA ⋅ μM−1 ⋅ cm−2, and the limit of detection is 0.64 μΜ. The composite electrodes are characterized by outstanding reproducibility, superior stability and strong selectivity.
