Focusing on ionophore-based ion-selective electrodes (ISEs), this work highlights recent advances in increasing sensor sensitivity by converting potentiometric response to a variety of electrical and optical signals including charge, current, luminescence, color change.
The field of optics has a drastic impact in the field of electronics and communication. With the rising need for higher data transfer rate, optical advancements have served this purpose. Optical amplifiers play a crucial role in the amplification of signal at regular intervals to avoid loss of data. Erbium doped fiber amplifiers (Erbium Doped Fiber Amplifier) carry out the amplification by stim...

Tyramide signal amplification (TSA) is a reagent based method for amplification of weak signal in immunofluorescence, immunohistochemistry, in situ hybridization and similar image-based assays. Typically it provides 1-3 orders of magnitude improvement in the limit of detection, while reducing the exposure time and the amount of primary antibody or probe used in the assay. Here we demonstrate ap...
All-optical phase regeneration of a binary phase-shift keying signal is demonstrated at 10-30 Gb/s without a phase-locked loop in a phase-sensitive amplification-based system using Brillouin amplification of the idler. The system achieves phase noise reduction of up to 56% and up to 11 dB OSNR gain at 10-5 bit error rate for the 10 Gb/s signal. The system's sensitivity to different p...
