A series of ultrathin (80−100 nm) poly(ethylene glycol)−fullerene (PEG-C60) composite films were fabricated by three different methods, denoted immersion, one-pot, and reflux. These films are composed of cross-linked amine-/epoxy-decorated STAR-PEGs and disk-shaped C60 clusters with an average diameter of 314−329 nm and narrow size distribution. The clusters are located either on the surface of the films (immersion) or embedded in their bulk, coupling either physically (one-pot) or chemically (reflux) to the PEG network. The content of C60 in the composite films varies depending on the preparation method and is highest (∼30%) in the case of reflux, featuring also a shift of the lowest unoccupied molecular orbital energy of C60 by ∼70 meV compared to the immersion case. These films exhibit distinct optical and electrochemical properties of C60, merged with some favorable characteristics of the PEG matrix and resulting, in particular, in good electrochemical conductivity and high elasticity. The films can be separated from the substrate, forming composite nanosheets, which can be either used as free-standing ones or transferred to a secondary substrate with the preservation of the original properties. Potential applications of PEG-C60 films and nanosheets include flexible electronic devices, photodetectors, and electrochemical sensors, including biosensors in particular.

Fast technological progress has sped up the growth of telemedicine, mobile e-health services, and healthcare monitoring, which, nowadays, are technologies in high demand in the medical field and analytical sensing. Biosensing device design has promoted forefront research topics wherein new sensing technologies have been developed. In this regard, nanomaterials have had a crucial role wherein novel biosensors based on nanomaterials have emerged as detective tools for several biomolecules. Most biosensors are remarkably sensitive and selective to detect cancer biomarkers, toxins in foods, drugs, pathogenic microorganisms, cholesterol, pesticides, nucleic acids, glucose, heavy-metal contaminations, and other bioanalytes under different platforms at extraordinarily low concentrations (nanomolar, picomolar, or femtomolar). A comprehensive review of nanomaterials used for healthcare biosensing is offered herein. Specifically, this review offers a new point of view, highlighting and covering exhaustively several kinds of nanomaterials (<500 nm) to detect human diseases through biosensing. In this sense, we organize them into organic, inorganic, and carbon-based, thus offering a guide to selecting the best nanomaterial for specific detection. Further, it provides a roadmap to the real-time utilization of nanomaterials at a commercial scale. Also, this review addresses some crucial aspects of nanomaterials use and applications for healthcare biosensing. The progress discussed in this paper highlights the immense potential to implement the use of nanomaterials and nanocomposites in the initial examination of diseases and point-of-care testing.

In recent years, the invention of polymers have attracted attention due to their unique properties. (E)‐2‐cyano‐N‐cyclohexyl‐3‐(dimethyl amino) acrylamide (CHAA) is a new type of functional monomer created by the usage of 2‐cyano‐N‐cyclohexylacetamide (3) and dimethylformamide‐dimethylacetal (DMF‐DMA) utilized microwave energy as a green technology. In addition, polymers with significant nanosphere groups were obtained by polymerizing a new synthetic monomer (CHAA) with methyl methacrylate (MMA), dimethylaminoethyl methacrylate (DMAEMA) and acrylic acid (AA) using microemulsion polymerization technology. These polymer nanospheres were approved by different spectroscopic analyzes, such as FT‐IR, TEM, TGA, and H1NMR. New structurally defined poly (MMA/DMAEMA/AA/CHAA) nanospheres with an equivalent spherical diameter close to 50 nm and high thermal stability were obtained. In addition, these new polymer nanospheres exhibit good electrochemical performance and greater specific values compared to compound (CHAA) or poly (MMA/DMAEMA/AA). This is very important for the supercapacitor due to the fact that the voltammetry plots of these nanospheres display a well‐known hysteresis cycle. The newly synthesized polymer nanospheres exhibited antibacterial activity, which was confirmed by molecular docking simulations with different affinities. Also, the DFT investigation of the polymeric nanosphere was optimized utilizing B3LYP/6‐31(G) basis set and determination physical decribitors.
