Synthesis and characterization of gold nanoparticles and graphene oxide for the development of optical fiber biosensors.

Optical fiber technology, in association with the phenomenon of surface plasmon resonance (SPR), has opened a new gateway for quick, easier, and accurate sensing of various chemical, biochemical, and biological parameters. Continuous efforts can be seen in the direction of increasing the sensitivity of the optical fiber biosensors; thus, many hybrid nanostructured optical fiber biosensors composing different nanomaterials, nanomaterial combinations, and different 2D materials have been proposed in the past few decades. This paper discusses the synthesis, characterization, and applications of nanoparticles to the most favorable noble metal for SPR biosensing, i.

Fabrication and diameter analysis of a single-ended SMF tip structure.

Optical fiber technology combined with surface plasmon resonance enables rapid, precise detection of chemical, biochemical, and biological parameters. Many hybrid optical fiber structures have been suggested in recent decades to increase the sensitivity of optical fiber biosensors. In this work, an optical fiber tip structure is fabricated on single-mode fiber (SMF) by etching in a hydrofluoric acid (40%) solution at room temperature.

Low-cost fabrication and characterization process for development of a sensitive optical fiber structure.

The structure of silica single-mode fiber (SMF) must be modified in order to develop optical fiber-based biosensors. To reduce the diameter of the optical fiber, a low-cost chemical etching method is very popular. The proposed chemical etching method is a simple, rapid, and cost-effective technique for removing the silica cladding up to a desired diameter.

Optimized plasmonic reversible logic gate for low loss communication.

With the development of plasmonic optical waveguides, numerous nanostructures based on different materials can be fabricated in a controlled way. While doing reversible computing, reversible logic gates are the necessary requirement to reduce the loss of information with less power consumption. The proposed design of the Feynman logic gate is simulated by a cascading metal-insulator-metal optical waveguide based on Mach-Zehnder interferometers.

Ayurveda in Early Life to Prevent Noncommunicable Diseases From Epigenetical Alterations.

Context: The incidence of non communicable disease (NCD) is rising globally and is currently the leading cause of mortality and morbidity worldwide. Some evidence suggests that factors affecting growth and development from the period of conception through fetal life to early childhood and adolescence are major risk determinants for NCD later in life. Among them, epigenetic changes are drawing attention and remain largely unexplored.
