A group of researchers from the Rey Juan Carlos University have developed an electrochemical sensor, thanks to which it has been possible to analyze three of the most frequent β-blocking drugs in water.
Unfortunately, many drugs tend to appear frequently in environmental waters, such as underground, rivers or lakes, and even in drinking water, since they are usually not totally eliminated in sewage treatment plants. These pollutants, which pose a clear risk to human health and the animal and plant environment that surrounds us, are an emerging danger that requires better detection and prevention mechanisms.
In these events, a group of researchers from Rey Juan Carlos University have developed an electrochemical sensor, thanks to which it has been possible to analyze three of the most frequently prescribed β-blocking drugs worldwide (pindolol, acebutolol and metoprolol) in water .
Found for the first time simultaneously through this sensor, the drugs in question are used primarily to treat various conditions, such as heart rhythm disorders or as cardioprotectors after a myocardial infarction.
“The sensor developed in our research group is prepared in a simple way, mixing graphite paste with mineral oil and amino-functionalized mesostructured silica, in suitable proportions. In the work has been checked the high stability of the same, for use for long periods of time, as it is easily regenerable by a simple polishing operation “explains Isabel Sierra, responsible for this work.
“The development of cheap, easy-to-use, highly sensitive and portable devices for in-situ measurements is an additional advantage to the expensive conventional equipment used for this purpose in laboratories,” the scientists point out.
