Abstract: A permeable membrane support having a removable permeable membrane is disclosed The permeable membrane support includes a lower support having a hollow cylinder shape with an outer diameter smaller than an inner diameter of a plate well so to be accommodated in the plate well, wherein the lower support includes: an upper end having a first opening and a lower end having a second opening; an inner wall extending between the upper and lower ends and having an open channel defined therein and extending therebetween and communicating with the first and the second openings; a support surface portion extending inwardly from an inner surface of a lower end of the inner wall and having a central opening defined therein constituting the open channel; an upper support including: a cylindrical lower member constructed to be partially accommodated in the lower support; a pair of opposing wings constructed to be supported on a top of the plate well; and a deformable beam portion extending upwardly from an upper circumfere

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.
