Provided is a method of manufacturing a printed circuit nano-fiber web. A method of manufacturing a printed circuit nano-fiber web according to an embodiment of the present invention includes (1) a step of electrospinning a spinning solution including a fiber-forming ingredient to manufacture a nano-fiber web; and (2) a step of forming a circuit pattern to coat an outer surface of nano-fiber included in a predetermined region on the nano-fiber web using an electroless plating method. According to the present invention, a circuit pattern-printed nano-fiber web having flexibility and resilience suitable for future smart devices may be realized. In addition, a circuit pattern may be densely formed to a uniform thickness on a flexible nano-fiber web using an electroless plating method, and the flexible nano-fiber web may include a plurality of pores. Accordingly, since the printed circuit nano-fiber web may satisfy waterproofness and air permeability characteristics, it can be used in various future industrial fields including medical devices, such as biopatches, and an electronic device, such as smart devices.

A biocompatible Mg—P coating on the surface of a zinc-based biomedical material, and a preparation method and use thereof are disclosed. In the method, zinc and a zinc alloy are first subjected to surface pretreatment and then soaked in a phosphate solution at a constant temperature to form the Mg—P coating through chemical liquid deposition (CLD). The control on the composition, thickness and surface morphology of the coating is realized by using the CLD method. The biocompatible Mg—P coating has a thickness of 0.5 μm to 50 μm, is dense and uniform, and comprises a main component of zinc-magnesium-phosphate and a small amount of zinc phosphate.

Disclosed are a material with supercapacitance modified surface and a preparation method and application thereof. Specifically, the present disclosure introduces a material having a controllably supercapacitive surface. The surface is chargeable, the full-charged modified surface can interact with bacteria disturbing the electron transfer of respiratory chain of bacteria and inhibiting the growth and reproduction of bacteria in a short-term. The antibacterial rate can be improved by cyclically charging-discharging without losing capacitance, and prevent formation of biofilm of bacteria. The antibacterial system can quantitatively control the antibacterial process without affecting the biocompatibility of the material, and has the advantages of environmental protection and controllability.

The disclosure relates to methods and devices for measuring samples, such as biological samples, especially those at low abundance, with high sensitivity and at low cost. A sample is disposed on a shrinkable scaffold and the shrinkable scaffold is shrunk, reducing the area where the sample is distributed, so as to effectively concentrate the sample on the surface of the scaffold. In the event that a biological sample is covalently attached to a scaffold having a silica structure, the increase in signal enhancement is also due to optical effects stemming from covalent linkage of the biological sample onto the silica structure of the scaffold. Silica (SiO.sub.2) may be deposited onto a surface of a polymer film by functionalizing the surface of the polymer film to bind silica from a sol-gel solution, and coating the film with a sol-gel solution containing silica precursors, wherein solid silica from the sol-gel solution is deposited onto the surface of the polymer film. Also disclosed is an immunoassay platform comprising a silica-encapsulated first detection agent deposited on a polymer substrate.
