About us

Plazmonika is established in 2019 and is located in the campus of Laser Technologies in Vilnius (Lithuania). The company specializes in the development of SERS (Surface Enhanced Raman Scattering) substrates and beam shaping elements. Our products can be used in the production of highly sensitive, selective, stable, and low-cost electrochemical sensors and can be an excellent alternative to enzyme-coated electrochemical sensors, which have an unstable response and poor reproducibility due to their enzyme properties. Gold nanoparticles have electrochemical properties that make gold nanoparticle-modified ITO glasses very attractive in the production of biosensors.
