“…The sensor showed high sensitivity to the local refractive index change and the capability of working as a biochemical sensor. Since then, a large number of optical fiber-based LSPR sensors have been developed and reported for various applications [16,30,44,[105][106][107][108][109][110][111][112][113][114][115]. The majority of these optical fiber-based LSPR sensors described in the literature were fabricated by immobilizing gold nanoparticles on the decladed fiber core of a multimode optical fiber.…”

Noble metal nanoparticle-based localized surface plasmon resonance (LSPR) is an advanced and powerful label-free biosensing technique which is well-known for its high sensitivity to the surrounding refractive index change in the local environment caused by the biomolecular interactions around the sensing area. The characteristics of the LSPR effect in such sensors are highly dependent on the size, shape and nature of the material properties of the metallic nanoparticles considered. Among the various types of metallic nanoparticles used in studies employing the LSPR technique, the use of gold nanorods (GNRs) has attracted particular attention for the development of sensitive LSPR biosensors, this arising from the unique and intriguing optical properties of the material. This paper provides a detailed review of the key underpinning science for such systems and of recent progress in the development of a number of LSPRbased biosensors which use GNR as the active element, including an overview of the sensing principle, the synthesis of GNRs, the fabrication of a number of biosensors, techniques for surface modification of GNRs and finally their performance in several biosensing applications. The review ends with a consideration of key advances in GNR-based LSPR sensing and prospects for future research and advances for the development of the GNR-based LSPR biosensors. Contents

The purpose of this study is to fabricate a stainless steel protector for a weak fiber sensor after first stripping the polymer outer-layer off the fiber. In addition to protecting the fiber sensor, the stainless steel protector is required to connect the detection target and the sensor which requires drilling holes in the protector. We accomplished this by electrochemical micromachining the stainless steel protector using pulse DC, using 1 kV/m, 6.62% weight concentration of NaCl electrolyte solution, 500 rpm anode rotating rate, a 5 MHz pulse frequency, a 50% duty factor, and 6 min of machining time with a ring cathode gave the best results, producing an average hole-radius of 231.36 lm.

This work comprehends a review of nanostructured materials employed in the fabrication of optical fiber sensors in the last years. The continuous advances in nanofabrication techniques have enabled to manipulate the matter precisely producing well defined nanostructurated coatings or repetitive patterns at nanoscale level. The interactions of light with these nano-organized materials or patterns at the nanoscale level enable to observe interesting phenomena, such as interferometry, fluorescence, absorbance, resonances and many others which can be exploited in the fabrication of sensing devices. A particular case consists of optical fiber sensors, where the light travelling through an optical fiber interacts with the sensitive layer. The properties of the sensitive layer, such as the organization, physical properties, chemical bounds etc. will determine the sensing characteristics of the final device. The utilization of some of the most common nanostructured materials, such as polymers, nanoparticles, metals, metal oxides or biological coatings are reviewed here.
