Development and commercialization of bio-sensor using cholesteric structure of magnetoplasmonic nanoparticle chain

Recently, bio-sensing R&D using plasmonic has been actively carried out in Korea and overseas. The global bio-sensing market is projected to grow rapidly by an average of 11.6% per year, with a high potential for future development and increased demand in the field. Helical nanostructure using magneto-plasmonic nanoparticles exhibit signals in visible light regions such as DNA and RNA, which are very easy to apply to biomedical fields. Signals represented by the structure of self-assembled helical nano chains are influenced by electron cloud signals of organic matter, resulting in wavelength shifts and these databases can be an indicator of the presence and qualitative determination of organic chiral moieties handedness. Therefore, micro-and miniaturization development, which implements the chiral three-dimensional structure of magneto-plasmonic nanoparticles on the substrate, is very necessary. The development of new micro-size bio-sensing devices provides a breakthrough technology that enables the early diagnosis of many intractable diseases.
