Ebook "Fluorescence in bio-inspired nanotechnology: First as probe, then as function" describes the evolving field of DNA nanotechnology in a lucid and easily accessible way. A central theme in the thesis is how biological structures and mechanisms constitute a basis for the design of novel technologies. Hannestad discusses how self-assembled, nanometer-scale DNA constructs can be functionalized using fluorescent labeling.

The engineered coupling between a guest moiety (molecule, nanoparticle) and the host photonic nanostructure may provide a great enhancement of the guest optical response, leading to many attractive applications. In this article, we describe briefly the basic concept and some recent progress considering the coupling of a single nanoparticle into a photonic structure.

The focus of this study is to investigate its optical and conductive properties under different conditions of doping environments, temperature and polymerization conditions. Optical characterization technique such as UV-Visible spectroscopy is developed to carry out the investigation. The developed nanofibers have been demonstrated to possess optical and conductive properties to be dependent on doping variables. Study of these optical properties could prove very useful in the development of electrochromic devices and gas sensors.

Radiation exposure due to the detonation of an improvised nuclear device remains a major security concern. Radiation from such a device involves a combination of photons and neutrons. Although photons will make the greater contribution to the total dose, neutrons will certainly have an impact on the severity of the exposure as they have high relative biological effectiveness.

The analytical expression for the self-Kerr nonlinear coefficient in a three-level V-type atomic medium is found in the presence of the Doppler effect. Based on the analytical results, we have analyzed the enhancement and control of the Kerr nonlinear coefficient under the condition of electromagnetically induced transparency. It is shown that the Kerr nonlinear coefficient is significantly enhanced around the resonant frequency of both the probe and coupling fields.

In this paper, one-dimensional photonic crystal distributed feedback structures were chosen for simulating the photonic modes. The corresponding photonic bands were calculated by using a numerical method for solving the master equation, while the reflectivity spectra of the structures were simulated by using a rigorous coupled wave analysis method.

In this paper, we present a review of enhancement and wavelength shift of abnormal upconversion green light emission from erbium ions doped in silica with narrow linewidth in the metallic-coated microsphere cavity. Although the phenomenon of the 537 nm- green light emission is not yet understood, its enhancement of several orders of magnitude seems to be due to the excitation of plasmons. The metallic-coated microsphere cavity has led to the lowest threshold so far observed in microsphere cavity lasers from 0.2 mW to 60 nW.

The results showed that the threshold intensity of OB in Λ-type system is much less than the other ones and the threshold intensity of OB in V-type system is the largest one. The analytical result is convenient to choose excitation configuration for experimental observations and related applications in photonic devices.
