Summary: This paper presents an optimized force sensor system using a modified plastic optical fiber bonded on a spring-steel cantilever. The performance of the sensor is enhanced by optimizing the position and characteristics of notches on the fiber. Experimental results demonstrate the excellent linear behavior of the optimized force sensor system in the range of 50 to 300 mN.

Summary: Two sensor configurations were developed and tested to measure micro/nano-liquid volumes. The proposed sensor chips, based on polymeric light diffusing fibers, demonstrated volume resolutions that were about seven times higher compared to a similar configuration without modifications. The sensors utilized changes in the mode profile of light to detect variations in resonance wavelength caused by micro/nano-liquid volumes deposited on sensitive patches.

Summary: A novel sensing method for temperature measurements of liquids using plasmonic resonance in multimode plastic optical fibers has been devised. The method involves connecting two different D-shaped POF platforms to measure temperature changes in the solution covering the thermosensitive platform. This approach allows for the measurement of temperature by varying the light launch conditions in the surface plasmon resonance POF sensor as a result of temperature changes.

Summary: A novel surface plasmon resonance (SPR) sensor was designed, realized, and investigated in this work. The sensor utilized a D-shaped plastic optical fiber shell (POFS) with a gold nanofilm coating to create a plasmonic-sensitive region. By injecting the solution under test into the microchannel of the sensor using a peristaltic pump, the need for microfluidic systems typically used in SPR configuration was eliminated. Experimental results demonstrated the sensor's high sensitivity and resolution, indicating its potential for biochemical sensing applications.

Summary: The paper explores a new measuring strategy that utilizes the Surface Plasmon Resonance (SPR) phenomenon in a different way from the classical methodology. Sensor systems based on this approach were designed and investigated to measure various physical features and realize chemical sensors. By altering the mode profile of the light in a multimodal waveguide, the proposed approach achieved a shift in resonance wavelength, allowing for separation of the measurand interaction zone and the SPR zone, and optimizing sensitivity.

Summary: A low-cost plasmonic sensor based on a polymeric light diffusive optical fiber (LDF) has been designed, realized, and experimentally tested. The sensor utilizes a gold nanofilm sputtered on the LDF for surface plasmon resonance (SPR), along with a simple modal filter achieved by covering the LDF with an aqueous solution. This modal filter effectively enhances the signal-to-noise ratio (SNR) of the SPR sensor by filtering out higher modes while maintaining sensitivity.

Summary: Two lossy mode resonance (LMR) platforms based on plastic optical fibers (POFs) were developed and tested for biochemical sensing. The platforms were created by combining zirconium oxide (ZrO2) and titanium oxide (TiO2) on the exposed core of D-shaped POF chips. The sensors were characterized as refractometers and functionalized with molecularly imprinted nanoparticles (nanoMIPs) specific for human transferrin (HTR), demonstrating high sensitivity and low detection limit.

Summary: In this study, a nanoplasmonic sensor chip based on a gold nanograting was tested using an experimental setup, and the orientation of the nanostripes forming the grating pattern was found to influence the biosensing performance, resulting in a best limit of detection of 23 pM for BSA detection. The longitudinal configuration showed two observable plasmonic phenomena sensitive to different BSA concentration ranges, ranging from pM to μM, which is important for various biochemical sensing applications requiring a wide working range.
