The present invention relates to a surface-enhanced Raman scattering patch and an attachable sensor using same. More particularly, the present invention relates to a surface-enhanced Raman scattering patch which allows continuous monitoring of drug administration and harmful substance detection to be accurately and easily performed, an attachable sensor using same, and a method for manufacturing same.

Surface-enhanced Raman scattering patch and attachable sensor using the same

A substrate including plasmonic continuous film with curved surface and a method for manufacturing the same. More particularly, a substrate for an ultrasensitive spectroscopic sensor includes bowl-shaped plasmonic curved nanodimples and spiked plasmonic nanotips formed at contact points between the nanodimples at the same time, thereby greatly increasing the total volume of hotspots and being capable of concentrating and analyzing an extremely small amount of a sample.

Substrate comprising plasmonic continuous film with curved surface and manufacturing method thereof

There are provided a substrate including a three-dimensional (3D) nanoplasmonic composite structure, a method of fabricating the same, and a rapid analysis method using the same. More specifically, there are provided a substrate including a 3D plasmonic-nanostructure/target-molecule composite thin film composed of an analyte and a plasmonic nanostructure and formed by applying a voltage to a plasmonic electrode in an electrochemical cell including an analyte and a metal precursor to induce an analyte molecule on the electrode and performing electrochemical deposition (or electrodeposition), a method of fabricating the same, and a rapid analysis method using the same.

Substrate including 3D nanoplasmonic composite structure, method of fabricating the same, and rapid analysis method using the same

A substrate formed by using a sliding dielectric film with a low surface energy that activates surface migration of metal adatoms and a method of manufacturing the same. More particularly, a substrate with a sliding dielectric film includes a substrate; a sliding dielectric film with a low surface energy formed on the substrate; and a nanoparticle formed on the sliding dielectric film, wherein the surface energy of the nanoparticle is at least 1000 mJ/mgreater than the surface energy of the sliding dielectric film. The substrate has a very high SERS enhancement factor with low light loss characteristics in the entire visible region by maximizing the plasmonic coupling between highly-dense and spaced-apart nanoparticles and between the lower substrate and the upper nanoparticles.
