Detection of microorganisms by magnetic separation and enzymatic conversion of urea. Urease modified gold nanoparticles are labeled with aptamers
to specifically detect desired microorganism. Upon addition of urea the impedance decreases proportionally. (Adapted from [136], with permission of Elsevier)
