“…Amoxicillin on modied GCE produced an oxidation peak with a low peak current at about +0.055 V, an oxidation peak at approximately +0.286 V, and an oxidation peak at +0.893 V, which can be attributed to AMX and capped AgNPs, respectively. 33,34 These ndings suggest that amoxicillin interacted with AgNPs@Sa-CPE. To summarize, the presence of silver nanoparticles improved the sensitivity of the detection of amoxicillin.…”

“…The silver nanoparticles were synthesized using an eco-friendly approach that involved saffron as a stabilizer and reducing agent. 33,34 In a 25 ml volumetric tube, saffron and silver nitrate (AgNO 3 ) were mixed in different ratios, from 1 : 1 to 1 : 9 and from 1 : 1 to 9 : 1 (w/w). A certain volume of caustic sodium (NaOH) was added to every mixture to adjust the pH to 10, followed by the addition of deionized water to reach the mark, and stirring for 5 minutes using a Vortex.…”

“…This oxidation peak could be attributed to the oxidation of crocin. [33][34][35] It is necessary to study the polymer lm in a solution that does not contain the monomer, so that any response of current arises solely due to the connection of Sa@AgNPs to the surface of GCE. The electrochemical response of the poly-Sa@AgNPs, formed on the GCE surface was studied in the absence of monomer in 0.1 mol L −1 acetate buffer pH 4.6 using cyclic voltammetry.…”

More than half of all Americans suffer from chronic diseases, the leading causes of death and disability. However, prompt treatment of chronic diseases can lead to better patient outcomes and a reduced burden on the healthcare system. This highlights the urgent need for electrochemical (EC) sensors that provide non‐invasive, real‐time monitoring of disease‐indicating biomarkers. Due to their high sensitivity, high selectivity, and cost‐effectiveness, EC biosensors have recently shown tremendous promise for individualized health monitoring. This review explains the working principles of EC biosensors. It summarizes the recent advances and improvements of EC biosensors for detecting biomarkers in different biofluids, including tears, saliva, breath, urine, and sweat. Through a comprehensive overview of EC biosensor technologies, this article is expected to aid the development of flexible and wearable EC biosensing systems that have the potential to provide continuous, long‐term health monitoring for both clinical and at‐home use.

The encapsulation of saffron holds great importance as it contributes to the improvement of its stability, purity, and targeted release of its bioactive components. The purpose of this review is to provide comprehensive information about the main methods for saffron encapsulation, types of encapsulation, and the current status of its patents in the field of food science. Numerous studies have been conducted to encapsulate saffron and its ingredients within micro/nanoparticles. According to them, nanoliposomes, polymeric nanoparticles, nanodroplets, and nanofibers have been employed for saffron encapsulation. These nanocarriers were synthesized using ultrasonication, emulsification, spray drying, freeze-drying, electrospinning, chemical synthesis, and ionic gelation. The size, stability, bioavailability, and release kinetics were crucial for their specific application. In general, ionic gelation, ultrasonication, and spray drying were the most popular methods for saffron encapsulation, respectively. Only a limited number of patents exist about nanosaffron for food science applications.
