A method for coating solid particles with a hydrophilic gel and particles coated by the method. |
摘要 |
<p>A method for coating solid particles with a hydrophilic gel, characterized in that as the said particles hydrophilic particles are chosen which are mixed with a gel-forming substance at a temperature which is above the gelling temperature. The gel-forming substance is made to cover each individual particle, whereafter the particles are separated from each other and cooled to a temperature which is below the gelling temperature. The invention also relates to particles coated in the above-mentioned manner. The gel-coated particles so obtained either may be used as such in various separating processes, e g as ion exchanger, if the gel-forming substance contains charged groups. Alternatively the gel-coated particles subsequently may be provided with suitable adsorbent groups, e g ion exchange groups, hydrophobic groups or groups with biospecificity. Examples of such groups are enzyme inhibitors, enzymes, antibodies and protein A from staphylococcus Aureus.</p> |
