The present disclosure relates to a composite membrane in which a rubbery polymer is introduced into a gutter layer to suppress the physical aging of the highly permeable composite membrane, and more particularly, to a composite membrane comprising a porous support layer; a gutter layer on the porous support layer; and an active layer on the gutter layer, wherein the gutter layer comprises a blend of poly(l-trimethlsilyl-l-propyne) (PTMSP) and a rubbery polymer and a method for preparing the same. The composite membrane according to the present disclosure has high permeation performance and a remarkable decline in physical aging leading to a decrease in permeability over time and thus has very high industrial applicability.

A clearing pretreatment method of a biological sample having a size of at most 1 mm, that is, a spheroid or organoid, according to the present invention uses a phosphate-buffered saline (PBS) rather than a conventional sucrose solution as a pretreatment solution, thus solving the problem in which the spheroid or organoid floats above the surface of water due to the density difference such that the structure of the sample is damaged. Therefore, there is an effect in that the spheroid or organoid can be transparentized while maintaining the original shape thereof, thus making it possible to image deep parts.

The present invention relates to a water degradable film comprising hyaluronic acid or a salt thereof and polyphenol compounds. The film of the present invention can transcribe nanofilms in the form of CNT (carbon nanotube), graphene and magnetic particles to various places. The film of the present invention can be dissolved by an aqueous solution or body fluid, and can be effectively used in the medical field since it is non-toxic and biocompatible. The film of the present invention can also be effectively used as a transcript that does not degrade the quality and performance of the device because no residue remains in the electronic device and the existing photolithography process.
