Etched Fiber Bragg Grating Biosensor Functionalized with Aptamers for Detection of Thrombin

Bekmurzayeva, Aliya; Dukenbayev, Kanat; Shaimerdenova, Madina; Bekniyazov, Ildar; Ayupova, Takhmina; Sypabekova, Marzhan; Molardi, Carlo; Tosi, Daniele (MDPI, 2018-12-06)

A biosensor based on an etched Fiber Bragg Grating (EFBG) for thrombin detection is reported. The sensing system is based on a Fiber Bragg Grating (FBG) with a Bragg wavelength of 1550 nm, wet-etched in hydrofluoric acid ...
FIBER OPTIC REFRACTIVE INDEX SENSORS BASED ON A BALL RESONATOR AND OPTICAL BACKSCATTER INTERROGATION

Shaimerdenova, Madina; Ayupova, Takhmina; Sypabekova, Marzhan; Tosi, Daniele (MDPI, 2020-10-30)

In this work, we introduced fabrication and interrogation of simple and highly sensitive fiber-optic refractive index (RI) sensors based on ball resonators built on the tip of single-mode fibers. The probes have been ...
OPTICAL FIBER BALL RESONATOR SENSOR SPECTRAL INTERROGATION THROUGH UNDERSAMPLED KLT: APPLICATION TO REFRACTIVE INDEX SENSING AND CANCER BIOMARKER BIOSENSING

Tosi, Daniele; Ashikbayeva, Zhannat; Bekmurzayeva, Aliya; Myrkhiyeva, Zhuldyz; Rakhimbekova, Aida; Ayupova, Takhmina; Shaimerdenova, Madina (MDPI AG, 2021-10-10)

Abstract: Optical fiber ball resonators based on single-mode fibers in the infrared range are an emerging technology for refractive index sensing and biosensing. These devices are easy and rapid to fabricate using a ...
SHALLOW-TAPERED CHIRPED FIBER BRAGG GRATING SENSORS FOR DUAL REFRACTIVE INDEX AND TEMPERATURE SENSING

Ayupova, Takhmina; Shaimerdenova, Madina; Tosi, Daniele (MDPI AG, 2021-05-24)

In this work, we present a gold-coated shallow-tapered chirped fiber Bragg grating (stCFBG) for dual refractive index (RI) and temperature sensing. The stCFBG has been fabricated on a 15-mm long chirped FBG, by tapering a ...
Wavelet-Based Demodulation of Multimode Etched Fiber Bragg Grating Refractive Index Sensor

Ayupova, Takhmina; Sypabekova, Marzhan; Molardi, Carlo; Bekmurzayeva, Aliya; Shaimerdenova, Madina; Dukenbayev, Kanat; Tosi, Daniele (MDPI, 2018-12-22)

Etched fiber Bragg grating (EFBG)-based sensors are used as evanescent field sensors for refractive index detection. When the fiber thickness is thin and the refractive index sensitivity increases, the number of propagating ...
