In this study, a label-free, selective and sensitive microcontact imprinted capacitive biosensor was developed for the detection of Escherichia coli. The recognition of E. coli was successfully performed by this sensor prepared with the combination of microcontact imprinting method and capacitive biosensor technology.

…Read MoreMolecular imprinting is known as an arti cial molecular recognition based technique in which a polymer network is formed with geometrically and chemically speci c binding sites complementary to the desired template molecule [1]. In principle, com- mercially available or chemically synthesized functional monomers are chosen to create a complex with the desired template via covalent chemistry or noncovalent interactions such as hydrophobic interactions, hydrogen bonds, Van der Waals forces and electrostatic interactions [2, 3].

Read MoreHeavy metals, such as lead, cadmium, mercury and arsenic (As) exert a toxic effect in surface water (sea, lake and river) and drinking water, which is harmful to many living organisms as they cannot convert these hazardous metals into harmless products. Among these, As is a highly toxic substance in drinking water throughout the world [1]. Long-term exposure to As, as a result of drinking As-contaminated water, can cause a wide range of dysfunctions and diseases from muscular weakness, melanosis, skin hardening, neurological and cardiovascular disorders to diseases such as restrictive lung cancer, gangrene, diabetes mellitus, hypertension and ischaemia [2, 3]. ...
