Product Info

How it works

The surface plasmon resonance is an optical phenomenon which has been successfully employed for studying the molecular specific interaction. This is fundamental for any sensing application. This instrument work in the Kretschmann configuration which is highly sensitive and ensures high resolution. The instrument is designed using a very stable 630 nm diode laser and a highly efficient array detector. The instrument offers fixed point-of-interrogation which ensures the fixed reference during the measurement. The optical arrangement enhances the reliability of measurement. The instrument utilizes a patented novel optomechanical scanning mechanism.

About us

About us

We are a team of active researchers in the field of soft condensed matter and related instrumentation. In 2010, we received a project from DST India under Instrument Development Programme for the development of low-cost and portable surface plasmon resonance (SPR) instruments with research grade resolution and sensitivity. We developed the instrument by employing a novel opto-mechanical scanning mechanism (Patent Application  # 2644/DEL/2014). We received a second phase of the DST, India Project in 2017 for transforming the lab prototype developed SPR instrument to a commercial equipment. We demonstrated and validated the equipment in two research labs of India viz. Raman Research Institute, Bangalore and CSIR-CEERI Pilani. The validation is satisfactory and hence the instrument is ready for its commercialization. 

 

We have very dedicated team members comprising of

Mr. Ashutosh Joshi (PhD scholar)

Dr. Raj Kumar Gupta (Thesis Supervisor and PI)

Dr. Manjuladevi V. (Co-PI)

Dr. Devanarayanan V.P. (Ex - PhD scholar)
