Abstract: A method, an electrochemical sensor and a system for selective detection of infections. The method detects a concentration of nicotinamide adenine dinucleotide, NADH, from a bacterial culture through a cyclic voltammetry or chronoamperometry applied to an electrochemically active polymer. Therefore, prokaryotic cells can be detected while eukaryotic cells remain undetected. The infections can include bacterial infections and fungi or yeasts microbial infections.

Abstract: A wound closure device, in particular a surgical suture, includes an elongated body and projections protruding from the elongated body. Each of the projections is in the shape of a fin-like angular anchoring element having a lower base part with a base length, an upper top part, and a height. The anchoring elements are arranged in a longitudinal direction along the length of the elongated body in at least two rows with a distance between any two anchoring elements in any row. Each anchoring element in a row is aligned relative to an anchoring element of any other row, and each section of the elongated body between two successive anchoring elements in a row has the same tapered shape in the longitudinal direction, with a steady change or an essentially steady change in the cross-sectional area of the elongated body.

Abstract: A device configured for antimicrobial, in particular bacteriostatic or bactericidal, activity, and a method for manufacturing the device. The device includes a device body having a surface. The device body is configured to anchor thermal nanoparticles supporting optical resonance, in particular localized surface plasmon resonance, at its surface. The device body includes thermal nanoparticles supporting optical resonance, in particular localized surface plasmon resonance, bonded to the surface of the device body. The thermal nanoparticles are capable of increasing their temperature by light irradiation in a wavelength range that matches with the wavelength of the optical resonance, in particular localized surface plasmon resonance, of the thermal nanoparticles. The device body also includes an antimicrobial substance that is releasable from the device body.

Abstract: The present invention relates to a modified surface capable of having bacteriostatic and bactericidal activity when it is light irradiated, thus converting the surface of the substrate into a bacteriostatic and a bactericidal surface as many times as it is desired, and for a long time. According to the invention, the modified surface upon light irradiation avoids the attachment of a microorganism to this surface, inhibits the formation of a biofilm on this surface and destroys an already formed biofilm on this surface. These effects can be achieved as many times as it is desired, and for indefinite time.
