EQUIPMENT / FACILITIES

Portable Surface Plasmon Resonance

A compact, custom-built analytical instrument designed for real-time monitoring of biomolecular interactions using Surface Plasmon Resonance (SPR) technology.

How it works/principle

SPR measures changes in the refractive index near a thin metal film surface (commonly gold) when biomolecules bind to immobilized ligands.
A polarized light beam excites surface plasmons at the metal–dielectric interface, and binding events cause a measurable shift in resonance angle or intensity.

Key features/ advantage

Portable and lightweight design for on-site or field measurements.
Label-free detection (no need for fluorescent or radioactive tags).
Real-time monitoring of molecular binding events.
Customizable sensor surface for different biomolecules.
High sensitivity with rapid response time.

Application

Detection of proteins, nucleic acids, antibodies, and small molecules.
Environmental monitoring (e.g., toxins, pollutants, pathogens).
Food safety and quality testing.
Medical diagnostics and point-of-care testing.
Drug discovery and biomolecular interaction studies

Yixist Visible Spectrometer

A compact UV-VIS mini spectrometer designed for rapid and accurate measurement of light absorption and transmission across a broad spectral range (180–1100 nm)

How it works/principle

The spectrometer works by dispersing incoming light into its component wavelengths through a diffraction grating.
A photosensor array (HAM S11639) detects the intensity of transmitted or absorbed light at each wavelength.
The resulting spectrum provides quantitative and qualitative information about sample

Key features/ advantage

Wide spectral range: 180–1100 nm (UV to near-infrared).
Compact, lightweight, and portable for flexible lab or field use.
High sensitivity and resolution with fast data acquisition.
Compatible with multiple light sources and optical fibers.
Low power consumption with user-friendly integration.

Application

Quantitative analysis of chemical and biological samples.
Absorbance and transmittance measurements of liquids, films, or solids.
Environmental monitoring (e.g., water quality testing, pollutant detection).
Food and pharmaceutical quality control.

Spin coater

A precision spin coating system designed for uniform thin film deposition of various materials onto substrates through controlled rotation.

How it works/principle

A liquid solution (photoresist, polymer, nanoparticle suspension, etc.) is dispensed onto a substrate.
The substrate is rapidly spun, and centrifugal force spreads the liquid evenly across the surface.
Film thickness is controlled by spin speed, acceleration, and duration.

Key features/ advantage

Wide range of programmable spin speeds and acceleration profiles.
High repeatability and uniform film coating.
Compatible with various substrate sizes and materials.
User-friendly interface with customizable recipes.
Compact and reliable design suitable for research and small-scale production.

Application

Fabrication of photoresist layers in micro- and nano-lithography.
Coating of polymers, sol-gels, and organic/inorganic thin films.
Deposition of perovskite, quantum dot, and nanomaterial films.
Optical and electronic device fabrication (sensors, LEDs, solar cells).
Research in material science, chemistry, and nanotechnology.
