“…The possible distortion of sensor response may not be only due to the adsorption processes but also because of secondary processes induced by water, for example swelling [38,50]. At the same time the effects of analyte induced water adsorbtion may be used for design and development of unique ultrasensitive approaches with detection limit up to 10 −17 g/L of potent xenobiotics (see 7.2, [51]).…”
