Abstract: The present invention discloses a method for modifying a non-planar electrode, in which a short-chain molecule is used as a connector. The short-chain molecule is an alcohol compound having a thiol group at both ends. Therefore, the thiol groups at both the ends of the short-chain molecule can be separately bonded to a nanoparticle and a surface of an electrode, so that a plurality of nanoparticles are arranged on a surface of a non-planar electrode.

Abstract: A blood sugar measuring apparatus includes a carrier, a measuring unit installed in the carrier, a calculation unit installed in the carrier and electrically connected to the measuring unit, a display unit installed in the carrier and electrically connected to the calculation unit, and a power unit installed in the carrier and electrically connected to the measuring unit, the calculation unit and the display unit. The blood sugar measuring apparatus is easy to measure the blood sugar without a significant psychological burden and discomfort, but with higher accuracy.

Abstract: Disclosed in the present invention is an enzyme-free glucose detection chip, including: a substrate; a detection portion, disposed on an end surface of the substrate; a plurality of protrusions, disposed at the detection portion; a conductive layer, disposed on a surface of the substrate having the protrusions; and a plurality of gold nanoparticles, dispersed on surfaces of the protrusions. In the enzyme-free glucose detection chip disclosed in the present invention, protrusions having gold nanoparticles are used as electrodes, are structures on a micrometer scale and a nanometer scale, and can directly react with glucose without any glucose oxidase or/and any medium.
