Abstract
Abstract
Background
Scopolamine is among the most essential tropane alkaloids used to remedy various nervous system disorders such as urinary incontinence, motion sickness, and spasmodic movements because of its anticholinergic and antispasmodic effects.
Objective
In this study, an optical nanosensor was fabricated using nano-Dragendorff’s reagent to detect and determine scopolamine in different plant parts at different stages of growth.
Method
For fabrication of the sensing phase, GO-g-PCA/DR was synthesized by encapsulation of Dragendorff’s reagent (DR) on the graphene oxide grafted with poly citric acid (GO-g-PCA) with ultrasonication for 15 min and stirred for 80 min at room temperature, and then it was immobilized on a triacetyl cellulose membrane. The kinetic absorption profiles were recorded at 360 nm, which is concerned with the reaction between immobilized GO-g-PCA/DR and different concentrations of scopolamine.
Results
The nanosensor showed a rapid, strong, and stable response to the scopolamine solution with changing the absorption spectrum at 360 nm. The reaction was completed in a period of 300 s. The SEM, AFM, and FT-IR analysis of nanocomposites and nanosensors show the successful synthesis of GO-g-PCA/DR and the reaction between nanosensor and scopolamine. All experiments were performed at the wavelength of 360 nm, room temperature, pH 7 (the scopolamine solution pH), and 300 s. The nanosensor had a linear range of 0.65 to 19.63 μg/mL and 0.19 ± 0.025 μg/mL as the limit of detection for scopolamine determination. In order to reuse the designed nanosensor, it was recovered with ethanol, and the color ultimately returned to its original state.
Conclusions
This in situ nanosensor can determine the scopolamine in real samples with easy reversibility, extended lifetime, and reproducibility of the sensing phase response.
Highlights
A sensitive, precise, and fast response optical nanosensor is designed for in situ determination of scopolamine in real samples.

Abstract
Hyoscyamine (HSM), which acts as an antagonist of the acetylcholine muscarinic receptor and can induce a variety of distinct toxic syndromes in mammals (anti-cholinergic poisoning), is hazardous to human health. Therefore, it is urgent to develop a rapid, sensitive, and cost-effective method to determine HSM. A fluorescent microsphere based immunochromatographic assay was developed for this analyte and gold nanoparticles (AuNPs) were used as a comparison. A monoclonal antibody against HSM was prepared with a 50% inhibition concentration (IC50) of 1.17 ng mL-1, with no cross-reactivity with five drugs. Under optimized conditions, the cut off limits using the fluorescence-labeled monoclonal antibody strips were 10 ng mL-1 in 0.01 M PBS and 20 ng mL-1 in pork, pig urine, and honey samples, and the assay could be completed within 10 min. In comparison with a AuNP immunochromatographic assay, the developed method offered a higher coupling rate and lower amounts of antibodies. This approach could be used for simple, sensitive and rapid screening, and is suitable for on-site screening applications.
