Vesicular silica was synthesized using tetramethylorthosilicate[Si( OCH3)4,TMOS] as silica source and P123( EO20PO70EO20) as the structure-directing agent in phosphate buffer solution( p H = 6).Then,P123 was removed by extraction with ethanol. The synthesized siliceous materials were characterized by scanning electron…
Despite efforts in peripheral nerve injury and regeneration, it is difficult to achieve a functional recovery following extended peripheral nerve lesions. Even if arti- ficial nerve conduit, cell components and growth factors can enhance nerve regeneration, integration in peripheral nerve repair and regeneration remai…
