Abstract

Abstract The biotechnology sector is focusing on developing biosensors that allow us to detect and monitor substances in vivo using non-invasive methods. For example, in substances detection using the label-less method, radiation in the mid-infrared (mid-IR) has been used to obtain the vibrational fingerprint. In this work, we propose to use plasmonic nanoantennas called spaceship to develop a SEIRA substrate that can be used in disease detection. The spaceship nanoantennas were fabricated using electron beam lithography. A potential SEIRA device was fabricated with Au spaceship nanoantennas based on crop circles with dimensions of 5.5 µm long and 5 µm high. The resonance frequency (νres) was analyzed using gold nanoantennas absorbance as a function of frequency where one peak wasfound at 33THz. Additionally, these results were corroborated with a simulation where the magnitude of the electric field E = 7.79 V/m at 30.02 THz was found, and in E = 3.42 V/m at 79.97 THz is shown. These results allow us to propose spaceship nanoantennas as good candidates for the design of a SEIRA substrate.
