Zn2+-loaded cellulose beads stabilized by chitosan and prepared via freeze-drying for removing human testosterone in plasma.

In this study, chitosan was used to coat the adsorbent for preventing the leakage of Zn2+ loaded. Meanwhile, freeze-drying method was used to enhance adsorption capacity of Zn2+-loaded cellulose beads for testosterone. The results indicate that after the adsorbent was coated by 0.02% chitosan solution, the highest adsorption percentage reached 48%, during adsorption, the Zn2+ concentration in plasma did not increase; the adsorption capacity of the adsorbent can be significantly enhanced by freeze-drying. The results may be caused by porosity of the adsorbent enlarged via freeze-drying and improved stability by coating with chitosan. In addition, the adsorbent shows better selectivity and storage stability and could be a potential adsorbent to treat prostate cancer. PMID: 29774753 [PubMed - as supplied by publisher]
