The combined effects of nano titanium dioxide (TiO2-N) and clove oil (CO) on the physico-chem., biol. and structural properties of chitosan (CH)/starch (ST) films were investigated by using a solvent casting method. Results indicated that the incorporation of TiO2-N could improve the compactness of the film, increase the tensile strength (TS) and antioxidant activity, and decrease the water vapor permeability (WVP). As may be expected, the incorporation of CO into the film matrix decreased TS but increased the hydrophobicity as well as water vapor barrier antimicrobial and antioxidant properties. Fourier-transform IR spectroscopy (FTIR) data supported intermol. interactions between TiO2-N, CO and the film matrix. Use of a scanning electron microscope (SEM) showed that TiO2-N and CO were well dispersed and emulsified in the film network. Thermogravimetric (TG) and derivative thermogravimetric (DTG) curves demonstrated that TiO2-N and CO were well embedded in the film matrix, hence this blend film system could provide new formulation options for food packaging materials in the future. In the experiment, the researchers used ABTS Diammonium(cas: 30931-67-0Safety of ABTS Diammonium)

The title of the article was 《Biomass-derived nanocellulose aerogel enable highly efficient immobilization of laccase for the degradation of organic pollutants》.Electric Literature of C18H24N6O6S4 The author mentioned the following in the article:

Laccase is a promising biocatalyst for pollutant degradation and water purification However, laccase can only improve the stability of enzyme activity and achieve its significant catalytic effect after effective immobilization. Herein, we report a general strategy to integrate nanocellulose aerogel and laccase for high-efficiency degradation of organic pollutants. Biomass-derived functional bacterial cellulose (BC) aerogel with a nanonetwork structure and high porosity was prepared by biosynthesis, solvent replacement, and atom transfer radical polymerization (ATRP) procedures. Subsequently, a biocatalyst platform was fabricated by “”coupling”” ATRP-modified BC aerogel with abundant active sites with laccase through ion coordination. The results demonstrated the biocatalyst platform not only has good biol. affinity, but also has high enzyme load and structural stability. Meanwhile, the degradation rates of reactive red X-3B and 2, 4-dichlorophenol reached 94.5% and 85.2% within 4 h, resp. The strategy disclosed herein could provide a practical method for the degradation of organic pollutants.

ABTS Diammonium(cas: 30931-67-0) belongs to anime. Nitrous acid converts secondary amines (aliphatic or aromatic) to N-nitroso compounds (nitrosamines): R2NH + HNO2 → R2N―NO. Some nitrosamines are potent cancer-inducing substances, and their possible formation is a serious consideration when nitrites, which are salts of nitrous acid, are present in foods or pharmaceutical preparations. Tertiary amines give rise to nitrosamines more slowly; an alkyl group is eliminated as an aldehyde or ketone, along with nitrous oxide, N2O.Electric Literature of C18H24N6O6S4

Majerska, Monika; Jakubec, Martin; Klimsa, Vojtech; Rimpelova, Silvie; Kral, Vlastimil; Stepanek, Frantisek published an article in Molecular Pharmaceutics. The title of the article was 《Microgel bioreactors for cancer cell targeting by pH-dependent generation of radicals》.Quality Control of ABTS Diammonium The author mentioned the following in the article:

The lack of specificity of traditional cytostatics and increasing resistance of cancer cells represent important challenges in cancer therapy. One of the characteristics of cancer cells is their intrinsic oxidative stress caused by higher metabolic activity, mitochondrial malfunction, and oncogene stimulation. This feature can be exploited in the pursuit of more selective cancer therapy, as there is increasing evidence that cancer cells are more sensitive to elevated concentrations of reactive oxygen species than normal cells. In this study, we demonstrate a new concept for cancer cell targeting by in situ production of radicals under physiol. conditions. The biol. active radicals are produced in the milieu of cancer cells by enzymic conversion from an inactive precursor, 2,2′-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid)diammonium salt, by using miniature bioreactors represented by cell-sized microgels containing immobilized laccase. We utilize the pH-dependent activity of laccase to generate radicals only at a lower pH (5.7-6.1) that is characteristic of the tumor microenvironment. The composition of the microgels was optimized so as to allow sufficient substrate and radical diffusion, high enzyme activity, and stability under physiol. conditions. The functionality of this system was evaluated on three cancer cell lines (HeLa, HT-29, and DLD1) and the cytotoxicity of in situ-produced radicals was successfully proven in all cases. These results demonstrate that cancer cell targeting by in situ-generated radicals using miniature enzymic reactors may represent an alternative to traditional cytostatics. In particular, the pH-dependence of radical generation and their short-lived nature can ensure localized functionality in the tumor microenvironment and thereby reduce systemic side-effects. In the part of experimental materials, we found many familiar compounds, such as ABTS Diammonium(cas: 30931-67-0Quality Control of ABTS Diammonium)

Electric Literature of C18H24N6O6S4On March 22, 2020, Thepchuay, Yanisa; Sonsa-ard, Thitaporn; Ratanawimarnwong, Nuanlaor; Auparakkitanon, Saranya; Sitanurak, Jirayu; Nacapricha, Duangjai published an article in Analytica Chimica Acta. The article was 《Paper-based colorimetric biosensor of blood alcohol with in-situ headspace separation of ethanol from whole blood》. The article mentions the following:

This work presents a novel development that exploits the concept of in-situ gas-separation together with a specific enzymic colorimetric detection to produce a portable biosensor called “”Blood Alc. Micro-pad”” for direct quantitation of ethanol in whole blood. The thin square device (25 mm × 25 mm × 1.8 mm) comprises two layers of patterned filter paper held together with a double-sided mounting tape with an 8-mm circular hole (the headspace). In operation, the reagent is deposited on one layer and covered with sticky tape. Then 8μL of a blood sample is dispensed onto the opposite layer and covered with sticky tape. Diffusion of ethanol across the 1.6 mm narrow headspace permits selective detection of ethanol by the enzymic reagents deposited on the opposite layer. This reagent zone contains alc. oxidase, horseradish peroxidase and 2′-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid) diammonium salt, as the chromogenic reagent. The color intensity, measured from the recorded digital image, resulting from the enzymic assay of ethanol, correlates with the concentration of blood alc. The results obtained with spiked mice and sheep blood samples, using an external calibration in the range of 1-120 mg dL-1ethanol, gave recoveries of 93.2-104.4% (n = 12). The “”Blood Alc. Micro-pad”” gave good precision with %RSD <1 (50 mg dL-1 ethanol, n = 10) and limit of quantification (10SD of intercept/slope) of 11.56 mg dL-1. The method was successfully validated against a headspace gas chromatog.-mass spectrometric method. It has good potential for development as a simple and convenient blood alc. sensor for on-site testing. The results came from multiple reactions, including the reaction of ABTS Diammonium(cas: 30931-67-0Electric Literature of C18H24N6O6S4)
