About Us
PICSSL Lab
The Polymer and Inorganic Composites, Structures and Surfaces Lab (PICSSL) is a material science focused group within the Department of Mechanical Engineering at the Lassonde School of Engineering, York University. Led by Dr. Reza Rizvi, our group works with various types of polymer and inorganic materials, focusing on their composites, structures, and surfaces. We leverage industrially scalable synthesis methods to provide solutions for applications in manufacturing, electronics, energy, and health.

OPTIR System
mIRage OPTICAL PHOTOTHERMAL INFRARED SPECTROSCOPY (O-PTIR)
The Solution: O-PTIR uses a collinear visible light source to detect IR absorption, which results in non-contact measurement, thus requiring little or no sample preparation before analysis. Since the light "probe" is used to detect the thermal expansion of the sample, the spatial resolution is independent of infrared light and the submicron infrared spatial resolution is reached.
HIGHLIGHTS
- 1.Sub-micron spatial resolution
- 2.Non-Contact measurement (far-field)
- 3.Transmission FTIR quality spectral quality in reflection
- 4.Live cell imaging in water
- 5.Little to no sample preparation
- 6.Simultaneous IR + Raman
Best of Both Worlds
O-PTIR offers the convenience of a contactless reflection mode technique combined with the quality of FTIR transmission spectra. It allows for spectra collection on thick samples (e.g., 20 µm) with high database match rates for materials like Polystyrene (PS), PET, and PMMA.
