Abstract: The present disclosure relates to a surface-enhanced Raman spectroscopy complex probe capable of effectively detecting a catecholamine compound even at extremely low concentrations. The complex probe includes a nanolaminate including a nanogap and metal nanoparticles. In this case, the nanolaminate and the metal nanoparticles are modified to a compound that may be bound to each functional group included in catecholamine, and thus, catecholamine included in an analyte is doubly recognized by the complex probe. In addition, since a hotspot emitting a strong SERS signal is formed by a nanogap included in a nanolaminate, it is possible to effectively detect a catecholamine compound even at extremely low concentrations.

Abstract: The present invention relates to particle measuring apparatus and a particle measuring method, whereby particle counts per size range can be measured with a high accuracy using a laser power scanning in which lasers of several powers are sequentially irradiated. First, minimum powered lasers capable of measuring particles having more than relevant size are irradiated to a particle measurement space for a predetermined time in response to plural counts of each mutually different particle size, and the counts of particles per size are measured by detecting a scattered light. Furthermore, the counts of particles belonging to each size range can be accurately calculated through an algorithm using the actually measured value.

Abstract: An apparatus and method for detecting composite material damage due to impact by using distributed optical fiber are disclosed. In the apparatus and method for detecting composite material damage due to impact by using distributed optical fiber, the position and level of damage occurring in a composite material due to low-velocity impact can be effectively and economically detected by measuring the residual strain of optical fiber distributed on the surface of the composite material or inside the composite material. In the apparatus and method for detecting composite material damage due to impact by using distributed optical fiber, there is no need to always operate a sensor in real time, so that detection errors due to temporary failures, malfunctions, etc. of the sensor, as well as a problem of constantly supplying power to the sensor, can be essentially removed.
