Fiber-in-Tube Design of a CuFe2O4@Conducting Polymer with Synergistically Enhanced Peroxidase-like Activity for Total Antioxidant Capacity Assays

“…During the past few years, a mass of functional nanomaterials such as precious metals, metal oxides, metal sulfides, nanocarbons, metal–organic frameworks, and inorganic–organic nanohybrids have been demonstrated to possess peroxidase-like activities. − However, their catalytic activities are still significantly lower than that of natural enzymes, and there is still a lot of space for promoting the enzyme-like efficiency of those nanozymes. Recently, several strategies have been utilized to promote the enzyme-like catalytic performance of nanozymes, including the regulation of their size and morphology, modulation of the electronic structure by doping with heteroatoms and interfacial engineering, and ligand modification. − Recently, confinement catalysis has been of particular interest due to its dramatically enhanced catalytic efficiency with up to an order of magnitude . Generally, the active components confined in a hollow structure can affect their electronic states by the coordination environment, thus optimizing the adsorption energy of the catalytic intermediates and resulting in an enhanced catalytic efficiency and selectivity .…”

Simple, Skin-Attachable, and Multifunctional Colorimetric Sweat Sensor

“…Because of their easy operation, low cost, and convenience, wearable sensors are playing one of the most important parts in early diagnosis and health monitoring, − particularly in recent years and the near future. − Integrating multiple functionalities in a single wearable sensor , has become mainstream recently because of its usefulness in practical sensing applications. , Employing wearable sensors, noninvasive detection of the components in body fluids such as sweat, , saliva, tears, and urine can be realized to gain information on the possible illness and/or health state of human beings. For example, in body fluids, excessive chloride is an indicator of cystic fibrosis and the pH level is a marker of metabolic alkalosis, the concentration of cortisol reflects the psychological situation of depression and anxiety, , an abnormal concentration of glucose may indicate diabetes, − and an abnormal concentration of lactate may indicate a metabolic disorder. , Therefore, integrating multiple sensing abilities for these ions and metabolites can help to monitor multiple illnesses and/or health states simultaneously. , …”
