Surfactant-Based Electrodes for the Quantification of Flavonoids

Abstract

Flavonoids are a class of phytochemicals that have a wide variety of advantageous biochemical and pharmacological qualities. Flavonoids are often derived from natural sources, originating from plants such as fruits, vegetables, tea, wine, seeds, herbs, spices, and whole grains. Fruits and vegetables contain flavonoids, which offer several health advantages. They are known to demonstrate a wide range of biological and pharmacological actions, including antioxidant, antiallergic, antibacterial, antiinflammatory, antimutagenic, and anticancer properties. Recent research suggests that a flavonoid-rich diet in adults reduces plasma levels of total cholesterol, low-density lipoproteins, and triglycerides, as well as the risk of cardiovascular disease and osteoporosis. Surface-activated agents, surfactants, are widely used in many industrial products covering medicine and medical fields as well as daily life, such as detergents, drugs, and anticorrosive treatments. Surfactants, important in many application areas such as chemistry, biotechnology, medicine, and agriculture, are classified according to their water solubility. From the point of quantification of flavonoid, the surfactant can be mixed with different nanomaterials and substances and immobilized on the top of the electrodes, or they can be added to the solution where the analyses take place. This chapter provides information about flavonoids and surfactants, their chemical properties, structures, and usages, with the aspect of electrochemical methods. © 2024 Elsevier Inc.
