SEE THE ATTACHED FILE WITH TABLES AND FIGURENUMEROSI INDUSTRIAL, TECHNOLOGICAL AND BIOMEDICAL SECTORS HAVE THE URGENT NEED TO MONITOR THE LEVEL OF CHEMICAL AND MICROBIOLOGICAL CONTAMINATION OF THE WATER USED AND THE WORKING ENVIRONMENTS. IDEALLY, SHOULD THE CONTROL SYSTEM BE ABLE TO RETURN A RESPONSE IN THE SHORTEST POSSIBLE TIME, WITH A HIGH LEVEL OF SENSITIVITY? WHAT ABOUT A SPECIFICITY? ELEVATA.THE CURRENT ANALYTICAL LABORATORY TECHNIQUES ALLOW TO MEET THE LAST TWO NEEDS, BUT ARE NOT ABLE TO MEET THE POSSIBILITY? A REAL-TIME DETECTION. BESIDES THERE? C? TO TAKE DUE ACCOUNT OF THE FACT THAT CONTAMINATED INTEREST IN NATURAL CONDITIONS? THEY ARE HARDLY ISOLATED WITHOUT INTERFERING SUBSTANCES/ORGANISMS AND ARE ALSO ALMOST INVARIABLY DISPERSED AT LOW CONCENTRATION.THE PROGRESS ACHIEVED IN RECENT YEARS BY NANOTECHNOLOGIES, MOLECULAR BIOLOGY AND APPLIED ELECTRONICS, LET
