Facilities and Equipment

CD spectrometer

Circular Dichroism Spectrometer: This newly assembled instrument will be retrofitted with a multi-angle cylindrical holder that could be used to study protein corona on nanomaterials. We also intend to use this for studying meta- and other chiral-nanomaterials such helically-coiled nanotubes.

Atomic force microscopy: Presently, we have a Veeco CPII system for our AFM needs. The picture shows a new version of AFM capable of scanning in liquids that will be installed in the Nano-biolab in early July. We aim to use AFM to explore the fundamentl interactions between proteins and nanomaterials.


Multi-photon imaging: This setup, which is very similar to the so-called open aperture Z-scan, attached to a pulsed ns (Continuum Surelite II-10)/fs (MaiTai BB) laser will be used to study multi-photon absorption coefficients for tuning defect-induced photoluminescence and use them in in-vitro and in-vivo biomedical imaging.


Fluorescence microscopy for the investigation of point-of-care disposable/recyclable biosensors and disease diagnostic tools. This is complementary to our efforts on Surface Enhanced Raman Sensing (SERS).


Spectra-physics MaiTai BB laser with 700-1000 nm tunable window at <80 fs resolution is coupled to our Z scan system. Currently, work is underway for coupling this laser to a confocal microscope for multiphoton imaging.


New Zetasizer nano90s with both hydrodynamic size and zeta potential capabilities. This is extensively used for nanoparticle characterization and studying protein corona.


CEM microwave reactor allows us to synthesize and functionalize nanomaterials for bio-applications and exploring nano-bio interactions.
