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.
