“…The measured values of LOD and LOQ were 2.01 and 6.71 mg urea-N/L, respectively, which are the lowest reported values for urea analysis by anthocyanin-based paper sensors. [28,29] Moreover, the biosensor presented high sensitivity of 0.018 pixel/mg urea-N/L with excellent optical visibility for urea concentrations as low as 5 mg urea-N/L, which is a significant achievement for visual urea detection. The biosensor also showed high precision of 7.69% for urea concentration of 30 mg urea-N/L with replicate analyses (n = 4).…”

“…The development of paper-based urea detection sensors provides a tool with unique benefits, including simplicity, cost-effectiveness, small sample, chemical intake, and biodegradability. [25,26] Presently, most paper-based urea sensing studies have been focused on urea detection in biological fluids, [27][28][29][30] except for a few of them aimed at non-biological fluids such as diesel exhaust fluids [31] and aqueous samples. [32] These methods offer simple, portable, disposable, sensitive, and precise analytical tools for urea detection.…”

We introduce a rapid anthocyanin-based paper sensor with very high sensitivity and optical visibility for colorimetric detection of urea. The working principle is based on a colour change from purple to blue upon sensor exposure to ammonia generated from urea hydrolysis in the presence of urease as a catalyst. To improve sensor sensitivity and optical visibility, anthocyanin storage, urease solvent, urea hydrolysis time, and temperature were investigated. The results indicated that the anthocyanin extracted from red cabbage and stored in dark and low-temperature conditions, urease extracted into water 55 + glycerol 45 (Aq 55 + G 45 ), and urea hydrolysis time of 40 min and temperature of 45 C offer the best detection condition. The fabricated sensor showed exceptional sensitivity of 0.018 pixel/mg urea-N/L with a very low limit of detection (2.01 mg urea-N/L) and a limit of quantification (6.71 mg urea-N/L). Moreover, the sensor reaction zone is optically visible for urea concentration as low as 5 mg urea-N/L, making it a promising tool for urea screening in diverse applications. The unique analytical features and accuracy of the sensor compared to the spectrophotometry method also suggest that it can be used as a replacement for environmentally unfriendly spectrophotometry methods for on-site urea determination.

“…Most materials that have UV-induced photochromism are colored using organic colorants. However, the limitations of UV-induced chromic organic pigments include poor photostability, photochromism inhibition, and expensive cost, which restricts their applicability [ 16 , 17 ]. The organic pigments photochromism relies on have structural switching.…”

Immobilization of Strontium Aluminate into Recycled Polycarbonate Plastics towards an Afterglow and Photochromic Smart Window

A transparent smart window made of recycled polycarbonate plastic (PCP) waste was prepared and immobilized with strontium aluminate phosphor nanoparticles (SAPN). It has afterglow emission, super-hydrophobicity, durability, photostability, good mechanical properties, ultraviolet protection, and high optical transmittance. To create an afterglow emission polycarbonate smart window (SAPN@PCP), recycled polycarbonate waste was integrated with various concentrations of SAPN (15–52 nm). SAP micro-scale powder was made using the solid-state high temperature method. The SAP nanoparticles were produced using the top-down method. To create a colorless plastic bulk, recycled polycarbonate waste was inserted into a hot bath. This colorless plastic was thoroughly combined with SAPN and cast to create an afterglow luminous smart window. To investigate its photoluminescence properties, spectrum profiles of excitation and emission were measured. According to the luminescence parameters, the phosphorescent colorless polycarbonate plates displayed a change in color to strong green under UV illumination and greenish-yellow in a dark box. The afterglow polycarbonate smart window displayed two emission peaks at 496 and 526 nm, and an absorption wavelength of 373 nm. Upon increasing the SAPN ratio, the hydrophobic activity, hardness, photostability, and UV protection were improved. Luminescent polycarbonate substrates with lower SAPN ratio demonstrated rapid and reversible fluorescence under UV light, while the higher SAPN content in the luminous polycarbonate substrates showed afterglow.

“…Another example is silica gel strips which have been developed for the detection of Fe (III) ions. The silica strips were impregnated with tannin, and because of the selective binding of tannin to Fe (III), the colorimetric detection of Fe (III) could be made by visual inspection, using anthocyanin, a red dye extracted from cabbage 8 – 10 . As paper test strips can be fabricated at low cost, they could easily be provided in large quantities for medical checkups and drug assessments 11 .…”

A one-step analysis method was developed for four types of amino acids using a microfluidic paper-based analytical device fabricated from chromatography filtration paper and laminate films. Aminoacyl-tRNA synthetase was used to detect each amino acid. The obtained laminated paper-based analytical device (LPAD) contained four enzymatic reaction areas. Colorimetric detection was performed based on the molybdenum blue reaction. A model method for the simple, easy, and simultaneous detection of several amino acid concentrations was suggested, in contrast to the conventional methods such as HPLC or LC–MS. The method provided a selective quantification at the ranges of 3.6–100 μM for tryptophan, 10.1–100 μM for glycine, 5.9–100 μM for histidine and 5.6–100 μM for lysine with a detection limit of 1.1 μM, 3.3 μM, 1.9 μM and 1.8 μM, respectively. LPAD fabrication was considerably simple, and the subsequent detection process was easy and required a short period of time (within 15 min).
