Surface engineering of human hair was successfully used as a self-supported electrochemical sensor to detect glucose in human serum. Polydopamine (PDA) was firstly grafted on hair by oxidative self-polymerization of dopamine and then the copper nanoparticles (CuNPs) were electrolessly deposited to achieve surface metallization of hair (hair@CuNPs). The hair@CuNPs composites with uniformly dispersed conductive layer in 8 µm thickness exhibited outstanding electrocatalytic activity towards glucose oxidation. Under optimal conditions, the amperometric response of glucose on hair@CuNPs composites as self-supported nonenzymatic glucose sensor covered two linear ranges of 0.002–5 mM and 5–35 mM, respectively, and the detection limit was 1.62 µM. The proposed method provides an easy and inexpensive way to fabricate hair@CuNPs biosensor for detecting glucose level in human serum samples, indicating that hair@CuNPs composites have promising practical applications in biological analysis.

Hydrogels have been utilized extensively in the field of cutaneous wound treatment. The introduction of nanomaterials (NMs), which are a big category of materials with diverse functionalities, can endow the hydrogels with additional and multiple functions to meet the demand for a comprehensive performance in wound dressings. Therefore, NMs-functionalized hydrogels (NMFHs) as wound dressings have drawn intensive attention recently. Herein, an overview of reports about NMFHs for the treatment of cutaneous wounds in the past five years is provided. Firstly, fabrication strategies, which are mainly divided into physical embedding and chemical synthesis of the NMFHs, are summarized and illustrated. Then, functions of the NMFHs brought by the NMs are reviewed, including hemostasis, antimicrobial activity, conductivity, regulation of reactive oxygen species (ROS) level, and stimulus responsiveness (pH responsiveness, photo-responsiveness, and magnetic responsiveness). Finally, current challenges and future perspectives in this field are discussed with the hope of inspiring additional ideas.

“…However, the electrochemical method has become a promising path forward because of its economical cost, simple operation, rapid detection, high sensitivity, and so forth. 11 The core of this research is the preparation of electrodes with excellent sensing properties for aN. So far, the commercial electrodes available for aN are dominated by the ion-selective electrode (ISE), biased toward the detection of NH 4 + rather than harmful but trace NH 3 unless coupled with an ammonia gas-sensing probe.…”

As a common water pollutant, ammonia nitrogen (aN) has adverse effects on human life and production. Therefore, it is of great significance to realize the precision prevention of aN. Here, gold nanoparticle (AuNP)-modified carbon cloth (CC) electrodes were prepared for aN detection using cyclic voltammetry (CV). The first electrode was synthesized by in situ loading of AuNPs on the flexible CC (AuNPs/CC), and the second electrode was obtained by deposition of graphene coating on this basis (AuNPs/CC@G). Their selective response to aN was attributed to the formation and transformation of the gold ammonia complex through the electrodissolution of AuNPs. Two electrodes had a wide quantitative range (0.001−10000 μM); meanwhile, the limits of detection (LoDs) were down to the nanomolar level. From the aN standard to a real water sample, both nanocomposite electrodes also exhibited excellent sensing performance in the aspect of anti-interference, reusability, reproducibility, stability, and recovery. In the simultaneous comparison, the superior results of AuNPs/CC@G have confirmed the realization of optimization, which provided an innovative solution for the efficient and accurate monitoring of aN in water.
