A tunable reflectance filter based on a metal–hydrogel–metal structure responsive to humidity and temperature is reported. The filter employs a poly(N-isopropylacrylamide)–acrylamidobenzophenone (PNIPAm–BP) hydrogel as an insulator layer in the metal–insulator–metal (MIM) assembly. The optical resonance of the structure is tunable by water immersion across the visible and near-infrared range. Swelling/deswelling and the volume phase transition of the hydrogel allow continuous reversible humidity- and/or temperature-induced tuning of the optical resonance. This work paves the way toward low-cost large-area fabrication of actively tunable reversible photonic devices.

A self-assembled 3D nanonetwork of Nickel and Nickel Oxide is synthesized by ultrashort pulsed laser through multiphoton ionization. The synthesized nanonetwork with tunable physiochemical property was investigated for cancer therapeutic and biomolecular sensing applications. In this thesis, the developed 3D nickel nanomatrix effectively regulated HeLa cancer cell adhesion and proliferation mimicking Extracellular Matrix (ECM). This behaviour explicitly demonstrated that the initial incubation period was devoted to baiting fibroblast and HeLa cells to proliferate upon the nanomatrix and subsequently the same nanomatrix exhibited cell trapping behaviour upon HeLa cells after an increased incubation period thereby controlling proliferation. The results brought new insight as to how HeLa cells behaved differently when compared to NIH3T3 fibroblast cells opening pioneering application in drug-free cancer therapy. To delve deeper into nickel nanonetwork for cancer therapy the laser ionization was manipulated to induce two distinct quantum theranosomes. Presently, quantum materials are limited due to 0D & 1D materials lacking biocompatibility resulting in coated materials with labelled tags for fluorescence excitation. The theranosomes mimicked tumor microenvironment by selectively accelerating the proliferation of mammalian fibroblasts cells while inducing cancer therapy. Furthermore, the theranosomes opened up label-free bioimaging probe for differentiating (HeLa & MDAMB-231) from mammalian fibroblast cells for cancer diagnostics. In-addition to label-free bioimaging, the development of an ultrasensitive biosensor for targeted biomolecule sensing was developed addressing the drawback faced with fluorescence imaging using Surface Enhanced Raman Scattering (SERS). We developed a SERS active nano-biosensor to detect chemical dye Crystal Violet (CV) and biomolecule glutathione(GSH). The Raman detection of crystal violet (CV) and glutathione (GSH) molecules was noted with 1 pM (1×10-12M) concentrations at (532 & 785nm) excitation wavelengths with an enhancement factor of 109, not been observed even in plasmonic materials. This extends the limit of detection (LOD), confirming suitability for chemical and biomolecular sensing. Additionally, the quantum confinement effect will result in an ultrasensitive sensor diagnosing and differentiating cancer cells from fibroblast cells. Based on the results in this thesis, the multifunctional feasibility of nano and quantum scale nickel structures arranged in 3D assembly for its direct application in cancer therapeutics, encompassing cancer bioimaging and diagnostics.

This review, published annually, provides an overview of advances in the field of Raman spectroscopy as found in papers published in the preceding calendar year in the Journal of Raman Spectroscopy (JRS), as well as in trends over the past decade across journals that have published papers important to the field of Raman spectroscopy. This information is obtained from statistical data on article counts obtained from Thomson Reuters ISI Web of Science Core Collection by year and by subfield of Raman spectroscopy. Additional information is gleaned from presentations at the XXV International Conference on Raman Spectroscopy (ICORS 2016) in Forteleza, Brazil in August 2016 and those featuring Raman scattering at SCIX 2016 organized by the Federation of Analytical Chemistry and Spectroscopy Societies (FACSS) in Minneapolis, Minnesota, USA in September 2016. Coverage is also provided for topics from the conference ECONOS 2016 held in April in Göteborg, Sweden and GeoRaman 2016 in June in Novosibirsk, Russia. Finally, papers published in JRS in 2015 are highlighted and arragned by topics at the frontier of Raman spectroscopy. From these various perspectives, it is clear that Raman spectroscopy continues to be a rapidly expanding field that provides sensitive photonic information of matter at the molecular level in an ever‐widening arena of novel applications.
