Two-Photon Induced CO-Releasing Molecules as Molecular Logic Systems in Solution, Polymers and Cells
Phototherapeutic applications of carbon monoxide(CO)-releasing molecules are limited because they require harmful ultraviolet (UV) and blue light for activation. We describe two-photon excitation with...
PublicationsDesign of Novel TiO2-SiO2 Core-Shell Helical Nanostructured Anti-Reflective Coatings on Cu(In,Ga)Se2 Solar Cells with Enhanced Power Conversion Efficiency
Introducing an anti-reflective coating (ARC) is the last step of fabricating Cu(In,Ga)Se2 solar cells with enhanced photogenerated current by reducing the reflectance of visible light. The use of nanostructures...
PublicationsProtein corona formation and its constitutional changes on magnetic nanoparticles in serum featuring a polydehydroalanine coating: effects of charge and incubation conditions
The inevitable formation of a protein corona upon contact of nanoparticles with different biological fluids is of great interest in the context of biomedical applications. It is well established that the...
PublicationsOptical manipulation, beam-shaping and scanner-free bright-field and dark-field imaging via multimode optical fibre
We present a powerful approach towards full understanding of laser light propagation through multimode optical fibres and control of the light at the fibre output. Transmission of light within a multimode...
PublicationsSingle laser beam based passive optical sorter
We demonstrate experimentally a new method of sorting of colloidal particle suspension in wide single laser beam. The sorting is performed in a realization of a "tractor" beam a weakly focused laser beam...
PublicationsExperimental demonstration of optical transport, sorting and selfarrangement using a “tractor beam”
We demonstrate experimentally the principle of a "tractor beam" where a microobject is pulled against the photons flow. We show that this geometry and method can be used to delivery several microparticles...
PublicationsExploiting multimode waveguides for pure fibre based fluorescence imaging
There has been an immense drive in modern microscopy towards miniaturisation and fibre based technology. This has been necessitated by the need to access hostile or difficult environments particulalrly...
PublicationsVisible Light-Activated Biocompatible Photo-CORM for CO-release with Colorimetric and Fluorometric Dual Response
We introduce a colorimetric as well as fluorometric dual response CO-releasing molecule as Mn(I) tricarbonyl complex with a nitrobenzodiazole (NBD) fluorophore. DFT and TD-DFT studies corroborate that...
PublicationsThe role of propagation invariant light modes in single and multi-photon imaging
Propagation invariant, 'non-diffracting' beams have found numerous applications in areas as diverse as filamentation, trapping, and photoporation. However, the prominent transverse structure of Bessel...
PublicationsApproximate model for analyzing band structures of single-ring hollow-core anti-resonant fibers
Precise knowledge of modal behavior is of essential importance for understanding light guidance, particularly in hollow-core fibers. Here we present a semi-analytical model that allows determination of...
