The Gap(s)

Nearly two-thirds of global consumers will make healthier choices in what they buy (EY future consumer index, Oct 2020). The world is growing fast, and we need to make sure that our food and water remain safe.

Most of the optical instrumentation for sensing and analysis (e.g., optical spectrophotometers), and their complementary equipment are very expensive. Today, when technology advances rapidly, and most infrastructure is miniaturizing - it is time to adapt to these changes.

The vast majority of substrates for sensing, and specifically referring to Surface Enhanced Raman Spectroscopy (SERS), are general and non-selective, used for multiple analytes.

Our Mission(s)

In this project, trusted by IIA, we aim to develop SERS plasmonic sensing devices (substrates) for the wide-spread use of various industries (home-land security, food/water safety, counter-freight, etc).
 

The goals are to enhance their robustness, increase their shelf-life, and functionalize them with selective ligands for higher bonding efficiency - making the optical detection far more effective (signal and cost).

Eventually, the plasmonic sensing devices would bring benefit to many end-users including: research laboratories, pharmaceutical companies, optical instrumentation retailers and manufacturers, etc.
