Special Issue Information

Dear Colleagues,

With the eminent advancements in the field of nanotechnology and their provision of numerous viable solutions to meet the challenges related to diagnostics, treatments, bioelectronics, and environmental applications, there is expanding demand for the further development and design of nanobiosensors. The design/construction of compact nanobiosensor devices can result in the provision of numerous unique features, including accurate detection, high selectivity at ultraconcentrations, convenience, ease of use, low cost, and a wide scope of utilization and on-site implementation. In addition, the current decade is witnessing a distinct interest in developing portable monitoring devices to meet the challenges associated with clinical diagnosis, with many applications in the healthcare and environmental sectors. The design and production of nanobiosensors requires an incredible effort, resulting from the merging and integration of many research disciplines including engineering disciplines, materials science, environmental, chemical, biological, and medical sciences. In this regard, the current issue intends to highlight advanced research studies in the field of design, manufacturing, and environment applications of nanobiosensors.

A new optical chemical sensor was fabricated based on incorporation of 2,2-furildioxime as a sensitive reagent into the nanopore of a transparent glasslike material through the sol-gel method which was suitable for determination of Ni2+ ions in aqueous solutions. The prepared sensors were composed of tetraethoxysilane (TEOS), 2,2-furildioxime, methanol, hydrochloric acid and Triton X-100. The sensors were constructed by dip coating onto glass substrates. The optimum response of the sensor toward Ni2+ ions was reached at pH 8.5 and the contact time for the formation of the complex at 10 min. The linear concentration of the calibration curve was in the range of 1–5 mg L−1 with a detection limit of 0.111 mg L−1, and quantification limit of 0.337 mg L−1. In addition, the relative standard deviation (RSD) was less than 5% in determination of Ni2+ with ten slide sensor membranes. The developed sensor was tested on Ni2+ determination in real water samples which was confirmed by the atomic absorption spectrophotometer method. Full article
