“…This parameter helps evaluate an optode's ability to prove accurate and consistent results even when drawn from different optode sets. Precision is generally expressed as relative standard deviation (%RSD) [22,27,28]. The research results on the Cr(VI) detection membrane show that the %RSD precision value of the optode in standard solutions is 1.88%.…”

Chromium is a heavy metal that is often found as a water pollutant. High concentrations of hexavalent chromium (Cr(VI)) ion in nature are toxic and carcinogenic, so their presence in water needs to be monitored. Detection of heavy metals in water was carried out using an optical sensor membrane (optode). The optode was fabricated from cellulose triacetate polymer with plasticizers (oleic acid and acetophenone), aliquot 336, and the chromoionophore 1.5-diphenylcarbazide (DPC). The success synthesis of optode was evidenced by FTIR and SEM characterization. The optode performance produces a linear response in detecting Cr(VI) ion in the concentration range of 0.02-0.40 mg/L with an R2 of 0.9930, as well as the best conditioning at pH 3. The detection and quantitation limits are 0.0055 mg/L and 0.0165 mg/L. The sensitivity of the chromium optode was excellence, with a molar absorptivity value of 8.8303 × 106 M-1cm-1. The performance test results of the chromium optode were acceptable because they meet the specified requirements for minimum detection concentration value.

“…A polymer inclusion membrane-based optode was developed via the immobilization of morin (Figure - 3b ) in poly(vinyl chloride) (PVC) membrane for colorimetric determination of Al(III) in water and pharmaceutical samples within 0.05–3 mg L –1 with a little interference from fluoride anions and Fe(III) ions . Another optode was also constructed based on morin (Figure - 3b )-modified triacetylcellulose for Fe(III) sensing in pharmaceutical, plasma, serum, and tap water samples with a wide dynamic range of 1.06 × 10 –10 to 4.73 × 10 –5 M …”

Because of numerous inherent and unique characteristics of phytochemicals as bioactive compounds derived from plants, they have been widely used as one of the most interesting nature-based compounds in a myriad of fields. Moreover, a wide variety of phytochemicals offer a plethora of fascinating optical and electrochemical features that pave the way toward their development as optical and electrochemical (bio)sensors for clinical/ health diagnostics, environmental monitoring, food quality control, and bioimaging. In the current review, we highlight how phytochemicals have been tailored and used for a wide variety of optical and electrochemical (bio)sensing and bioimaging applications, after classifying and introducing them according to their chemical structures. Finally, the current challenges and future directions/perspective on the optical and electrochemical (bio)sensing applications of phytochemicals are discussed with the goal of further expanding their potential applications in (bio)sensing technology. Regarding the advantageous features of phytochemicals as highly promising and potential biomaterials, we envisage that many of the existing chemical-based (bio)sensors will be replaced by phytochemical-based ones in the near future.
