King Mongkut's University of Technology Thonburi (KMUTT) Reports Findings in Nanotechnology (Determination of hydroquinone in beverages using colorimetric and electrochemical sensors on paper-based device).

A recent report from King Mongkut's University of Technology Thonburi (KMUTT) in Bangkok, Thailand, discusses the development of two techniques for the determination of hydroquinone (HQ) in beverages. The first technique is a colorimetric detection method using 4-(dimethylamino) benzaldehyde with alkaline conditions, while the second technique involves a multi-walled carbon nanotube/graphene oxide/copper/palladium/platinum nanomaterial on a screen-printed carbon electrode. The research concludes that the proposed device is portable, inexpensive, and can be used to determine HQ in real samples. This research has been peer-reviewed and may be of interest to those studying nanotechnology and its applications in the food industry. [Extracted from the article]
