<p>The use of polymers in biological applications is defined by the interactions promoted between living organisms and polymeric chains which are&nbsp;generally associated with the polymers' hydrophilic and hydrophobic behaviors. However these water-friendly structures are also very useful for other applications such as the adsorption of pollutants from sewage water. The modulation of the final properties of water-soluble and insoluble polymers tends to define the spectra of features associated with their final applications.</p>
