Special Issue Information

Dear Colleagues,

We would like to invite you to submit a manuscript for the Special Issue of Materials focused on the Design and Synthesis of Novel Optical Probes.

The use of optical probes for different kind of applications is currently undergoing a revolution, with the incorporation of many new kinds of optical techniques and new materials. Novel optical probes allow the visualization of different materials such as tissues, cells, proteins and macromolecular structures at all levels of resolution, functional states, chemical composition and dynamic analysis, by using photonic studies of nanoscale interactions in all disciplines (like biology and medicine), as well as sensing.

The last two decades have witnessed the explosion of nanoscale materials in optical probes for imaging and sensing. Recent integrative research efforts have included nanotechnology (fabrication and application) as a tool for developing new techniques and improving existing optical imaging techniques for real-time, sub-wavelength imaging of cellular processes; developing the next generation of nano-sensors to improve sensing applications; using nanoparticles or nanostructures for optical engineering methodologies; and very large scale and/or very sensitive detection down to the single molecule level.

The proposed Special Issue will focus on, but is not limited to, the following key items in optical, fluorescence, electron or X-ray microscopy with sensing applications: nanoparticle use in imaging and sensing; nanostructures used for sub-wavelength imaging; nanospectroscopy and nano-scale sensing applications. Papers will emphasize the fundamentals of photonics and sensing including:

  • development of novel optical probes for imaging or sensing,
  • functionalization of materials dedicated for novel optical probes,
  • optical imaging and sensing using nanophotonic optical probes ,
  • applications of nanophotonics (functionalized nanoparticles, surfaces, etc..)

Nitrogen-vacancy color centers in diamond are a very promising medium for many sensing applications such as magnetometry and thermometry. In this work, we study nanodiamonds deposited from a suspension onto glass substrates. Fluorescence and optically detected magnetic resonance spectra recorded with the dried-out nanodiamond ensembles are presented and a suitable scheme for tracking the magnetic-field value using a continuous poly-crystalline spectrum is introduced. Lastly, we demonstrate a remote-sensing capability of the high-numerical-aperture imaging fiber bundle with nanodiamonds deposited on its end facet. Full article

In this paper, we present our optimization tool for fluorophore-conjugated metal nanostructures for the purpose of designing novel contrast agents for multimodal bioimaging. Contrast agents are of great importance to biological imaging. They usually include nanoelements causing a reduction in the need for harmful materials and improvement in the quality of the captured images. Thus, smart design tools that are based on evolutionary algorithms and machine learning definitely provide a technological leap in the fluorescence bioimaging world. This article proposes the usage of properly designed metallic structures that change their fluorescence properties when the dye molecules and the plasmonic nanoparticles interact. The nanostructures design and evaluation processes are based upon genetic algorithms, and they result in an optimal separation distance, orientation angles, and aspect ratio of the metal nanostructure.

Microstructured optical waveguides (MOW) are of great interest for chemical and biological sensing. Due to the high overlap between a guiding light mode and an analyte filling of one or several fiber capillaries, such systems are able to provide strong sensitivity with respect to variations in the refractive index and the thickness of filling materials. Here, we introduce a novel type of functionalized MOWs whose capillaries are coated by a layer-by-layer (LBL) approach, enabling the alternate deposition of silica particles (SiO2) at different diameters—300 nm, 420 nm, and 900 nm—and layers of poly(diallyldimethylammonium chloride) (PDDA). We demonstrate up to three covering bilayers consisting of 300-nm silica particles. Modifications in the MOW transmission spectrum induced by coating are measured and analyzed. The proposed technique of MOW functionalization allows one to reach novel sensing capabilities, including an increase in the effective sensing area and the provision of a convenient scaffold for the attachment of long molecules such as proteins.

This manuscript presents a theoretical analysis of a diamond-based integrated optics structure for applications in biosensors. The geometrical, optical, and sensitivity properties of an integrated optical structure were theoretically analyzed and optimized for biosensor applications. The analysis focused on determining the waveguide properties, including the effective refractive index Neff as a function of refractive index nw and thickness dw of waveguide layer, refractive index of the hemoglobin cover layer ncH and substrate layer ns, homogeneous sensitivity dNeff/dncH, and modal field distribution of guided waveguide modes. The analysis was completed for two types of waveguide layer materials: undoped or boron-doped diamond films with or without the hemoglobin cover layer. The presented experimental results form a base for developing biosensor structures based on integrated optics for determining the properties of hemoglobin. Full article
