Data confidence 70 medium

How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

The study is devoted to the using of modified polyethylene terephthalate ion-track membranes with polyvinyl alcohol functionalizing layer for the separation of biological objects. A brief analysis of the peculiarities of microporous ion-track membranes formation is presented and influence of etching regimes on the membrane parameters is demonstrated. The way of the membrane surface modification with the hydrophylic layer of polyvinyl alcohol is shown and experimental studies of the effectivness of functionalized ion-track membranes application for living cell (human lung cancer) separation is carried out.
