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.

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.
