The role of film composition and nanostructuration on the polyphenol sensor performance
(2017-01-01)
The recent advances in the supramolecular control in nanostructured films have improved the performance of organic-based devices. However, the effect of different supramolecular arrangement on the sensor or biosensor ...
Layer-by-Layer Thin Film of Iron Phthalocyanine as a Simple and Fast Sensor for Polyphenol Determination in Tea Samples
(2016-10-01)
Polyphenols have attracted attention due to their antioxidant capacity and beneficial effects to health. Therefore, fast, inexpensive, and efficient methods to discriminate and to quantify polyphenols are of interest for ...
Polymeric chemosensor for the colorimetric determination of the total polyphenol index (TPI) in wines
We have developed a new method for the rapid and inexpensive determination of the total polyphenol index (TPI) in wines by simply immersing our sensory film in red or white wines and visually checking the colour change ...
Electrochemical sensor based on reduced graphene oxide and molecularly imprinted poly(phenol) for D-xylose determination
(2020-02-01)
The present work reports the development of an electrochemical sensor based on molecularly imprinted polymer for the determination of D-xylose. This is the first report of its kind in the literature. The sensor was prepared ...
Analysis of polyphenolic content in teas using sensors
(2019-01-01)
Tea is one of the most consumed beverages in the world. Green tea and Black tea are the most common and are both made from the same plant called Camellia sinensis. In South America, the most consumed tea is Mate tea from ...
Polyphenol Detection in Mate Tea Samples Using Iron Tetrasulfonated Phthalocyanine Modified Screen-Printed Electrode
(2019-11-15)
Fast, inexpensive, and efficient methods to determine polyphenols content are of interest to the food industry. Here, we propose an easy and fast sensor for the determination of polyphenol content in tea samples from a ...
HRP-based amperometric biosensor for the polyphenols determination in vegetables extract
(Elsevier Science SaLausanneSuíça, 2003)
How low does the oxygen concentration go within a sandwich-type amperometric biosensor? Part 2: Theory for PPO biosensors
(Elsevier Science SA, 2015-02)
A mathematical model to describe the amperometric response of a sandwich-type biosensor containing polyphenol oxidase as the recognition catalytic element is proposed. The model was solved numerically and the resulting ...
Selective determination of caffeic acid in wines with electrochemical sensor based on molecularly imprinted siloxanes
(Elsevier Science SaLausanneSuíça, 2014)
Mimetic biosensors composed by layer-by-layer films of phospholipid, phthalocyanine and silver nanoparticles to polyphenol detection
(2016-10-05)
Highly selective and sensitive modified electrodes have been the focus of many studies in sensing applications. Gene or enzymatic biosensors are greatly effective in this context, but they are often fragile and expensive. ...
