Research interests

Due to their unique nature, coloured materials have found various applications in our day-to-day life including energy harvesting systems, solar protectors, UV and thermo-sensors, smart textiles, food technology, beauty & cosmetics, fashion etc. Many of these applications have been inspired by natural systems, which have been successfully isolated, re-created and synthetically improved providing a great choice of multifunctional and smart materials.

My research interests lie on the frontier of PHYSICS CHEMISTRY MOLECULAR MEDICINE and underpin the synthetic aspects and utilisation of these organic colorants with distinct optical and photophysical properties.[1] My particular interest is in functional dyes which can be used for purposes other than just colouration, for instance imaging agents with large Stokes shifts and NIR dyes, inflammation sensors, antimicrobial agents and chromic dyes which change the colour upon an external stimulus. Novel synthetic methods of these functional dyes therefore are essential to meet particular requirements to fine-tune the spectroscopic properties or generate new coloured organic materials for specific purposes.

Colorants in Healthcare [2,3]

Many of these functional dyes are based on biological molecules such as photosynthetic and respiratory pigments, betalains, flavonoids etc. which show physiological activities including anti-microbial, anti-tumour, anti-ageing, anti-inflammatory, immunosuppressive etc. This fact has been extensively used in preparation of novel therapeutics and preventive measures in healthcare.

Photodynamic therapy (PDT) is a division of photomedicine and based on three key elements light, a PDT agent (photosensitiser) and oxygen. PDT has been successfully used to treat medical conditions such as cancer, skin and vision disorders. Moreover, PDT can be used as an alternative treatment against infectious pathogens; which due to a rise in antibiotics resistance is becoming increasingly important.

Organic nanomaterials [4]

Our recent studies showed that functional dyes can also be used in preparation of stable, structurally well defined self-assembled nano-meshes. The basic idea is a use of molecular building blocks with predetermined intermolecular bonding properties. Since molecular self-assembly is based on non-covalent interactions, the stabilisation energies are usually very low. This results in conventional self-assembled structures often being unstable even at moderate temperatures. Inducing covalent reactions between the corresponding molecular components is an appealing approach in the fabrication of nanoscale structures. These nanostructures have potential applications in novel sensing, energy conversion or catalytic devices and molecular templates for directing the growth of, for example, metal clusters with interesting catalytic or magnetic properties.
