Abstract: Disclosed is a permeable membrane support having an attachable and detachable permeable membrane, the permeable membrane support comprising: a lower support; an upper support partially accommodated into the lower support; and a permeable membrane disposed between the lower support and the upper support. When the upper support and the lower support are engaged with each other in a snap-fit manner, the permeable membrane is sandwiched between a bottom opening of a cylindrical lower member of the upper support and a top face of a bottom support portion of the lower support.

Abstract: Disclosed are a nanofiber mat, a manufacturing method thereof, and applications thereof as a mat for cell culturing or as a barrier membrane for guided bone regeneration (GBR). The nanofiber layer includes a nanofiber layer and a reinforcement pattern that is disposed on the nanofiber layer and adhesively connected with the nanofiber layer. The nanofiber layer and the reinforcement pattern are combined with each other by at least one of the melting-solidification of at least a part of the nanofiber layer together with the reinforcement pattern, the dissolution-solidification of the same, and the penetration of a part of the reinforcement pattern into the nanofiber layer, followed by solidification.
