Abstract:
... With the development of blood glucose monitoring medical devices, higher requirements are put forward for the sensitivity and detection limit of biosensors. Herein, a high-performance flexible enzymatic glucose biosensor was prepared by electrochemical deposition of dendritic gold nanostructure on carbon cloth substrate, then covalently immobilizing glucose oxidase on the dendritic gold, and then ...
... In this paper, we developed a sensor for on-site measuring beverage sucrose level based on cascade enzyme particles and a blood glucose meter. The cascade enzyme particles with sucrose hydrolyzing capability were prepared by co-precipitation of manganese carbonate, in which the stability of the enzymes was substantially enhanced by the particle encapsulation effect. The quantitative measurement of ...

Abstract:
... The design of enzymatic droplet-sized reactors constitutes an important challenge with many potential applications such as medical diagnostics, water purification, bioengineering, or food industry. Coacervates, which are all-aqueous droplets, afford a simple model for the investigation of enzymatic cascade reaction since the reactions occur in all-aqueous media, which preserve the enzymes integrit ...

Abstract:
... After starch is ingested by the human body, it is rapidly broken down into glucose, causing an increase in blood glucose, and high blood glucose can lead to a series of health complications. The aim of this study was to delay the digestion of starch by encapsulating it in chitosan-sodium phytate capsules. A chitosan-sodium phytate film was formed on the surface of starch granules by dropping a mix ...
... NO₂ is one of the major air pollutants. Exposure to NO₂ is associated with various metabolic diseases, such as non-alcoholic fatty liver disease (NAFLD), diabetes, cardiovascular disease, etc. Abnormal hepatic glycolipid metabolism is a key feature of metabolic diseases. However, few studies provide evidence for the effects of NO₂ inhalation on hepatic glycolipid metabolism. In this study, female ...

Abstract:
... Tree peony (Paeonia suffruticosa Andr.) has a short and concentrated natural fluorescence, and forcing culture is frequently used for its annual production. We previously found that defoliation is critical for tree peony to reflower in the autumn. In this study, we investigated how defoliation induced this process in more detail. We found that partial defoliation with only three top leaves remaini ...

Abstract:
... Many lactose-free dairy products are produced using commercial lactase, but not without problems such as the sweetish taste due to the presence of free glucose and galactose. The aim of the present study was to obtain a lactose-free version of direct-acidified mozzarella without using the enzyme, but removing lactose by curd washing and pressing. The best results were obtained with double curd was ...

... Biotreatment of high load hydrogen sulfide (H₂S) can lead to rapid acidification of a bioreactor, which greatly challenges the application of bio-desulfurization technology. In this study, the bio-desulfurization performance was improved by enriching acidophilic mixotrophic sulfur-oxidizing bacteria (SOB) by adding organics under extremely acidic conditions (pH < 1.0). A biotrickling filter (BTF) ...
