SERS-active substrates based on plasmon nanomaterials

Summary of the technology

University offers the production of SERS-active substrates based on plasmonic nanomaterials used for rapid analysis in medicine, biomedicine, and criminology. Compatibility of the fabrication process with technological operations of manufacturing microelectronics and MOEMS devices reduces their cost and allows integrating SERS-active regions with optical and electronic elements on a silicon chip and creating microfluidic devices.

Details of the Technology Offer

University offers the production of SERS-active substrates in batches of various volumes to:

1. Universities, research institutes, and organizations that carry out high sensitive detection of liquid, gaseous and solid analytes as well as scientific research on the study of bio-organic objects (proteins, fatty acids, DNA, etc.), determination their chemical composition, and etc. by Raman spectroscopy.

2. Private companies to use substrates as consumables for the demonstration of their equipment capabilities and for software development.

The area of the SERS-active region on the substrates varies from 0,01 cm2 to 1 cm2. The area of the finished substrate lays in a range from 0,5 cm2 to 9 cm2, depending on the customer’s request.

A detection limit can reach up to micromolar or attomolar concentrations depending on an analyte, for example, for the 6G rhodamine dye, it is 10-18 M.

The main advantages of the developed SERS-active substrates in comparison to their analogues on the market:

- compatibility of their fabrication process with the main technological operations of manufacturing devices of microelectronics and MOEMS (microoptoelectromechanical systems),

- reduced cost compared to the cost of commercially available analogues,

- high detection limit (from 10-4 to 10-18 M),

- high signal reproducibility and stability (signal spread is less than 13 %),

- increased resistance to oxidation,

- extended shelf life (from 1 to 36 months).
