Nanomaterials (NMs) are used in an extremely diverse range of products and are
increasingly entering the environment, driving a need to better understand their potential …

We demonstrate a vibrational microscopy technique with subdiffraction spatial resolution by
the use of saturation of coherent anti-Stokes Raman scattering (CARS). The saturated CARS …

A novel approach for spectral focusing using a single-beam coherent anti-Stokes Raman
scattering setup with a pulse shaper controlling the phase and amplitude is presented. By …

The effect of multi-longitudinal-mode interference on pump-probe Raman gain
measurements is studied as the functions of laser linewidth and correlation between the …

Surface modified mesoporous silica nanoparticles (MSNs) with reduced toxicity were
prepared for light and pH dual triggerable drug delivery system. Both 413 nm light and acidic …

Drug nano-/microcrystals are being used for sustained parenteral drug release, but safety
and efficacy concerns persist as the knowledge of the in vivo fate of long-living particulates …

We report a wide-field imaging method to rapidly and quantitatively measure the optical
extinction cross-section σext (also polarisation resolved) of a large number of individual gold …

The contribution in this thesis is a novel application of microwave cavity perturbation in the
characterisation of the fundamental properties of powders. This thesis shows that microwave …

Nanodiamonds (NDs) are the most biocompatible member of the carbon nanofamily which
are widely researched for diagnostic and therapeutic applications. Unlike other carbon …

Nanoparticles of many varieties are increasingly studied for use in the physical, chemical,
and biological sciences. Metallic nanoparticles exhibit morphology-dependent localised …
