Virus Sorbents Based on Polyaniline Interpolymer Complexes, Composites and their Sorption Properties

Adsorption of influenza A and B viruses on detonation nanodiamonds materials

“…We have shown that DND, soot and their complexes with PANI are also able to interact with influenza viruses and the interaction doesn't vary for different antigenic structure of the surface proteins-hemagglutinins of influenza B or influenza A (H1,H3,H5) viruses. Earlier we have shown that influenza viruses can interact with other carbon materials: nanotubes and modified heat-treated graphite, as well as with carbon nanotubes, covered by PANI [3]. We have confirmed that both -DND and soot are efficient sorbents for cDNA with the fragment sizes above 200 b.p.…”

“…Virus titers before and after contact with sorbent were evaluated by hemagglutination test [6]. The contact of viruses or cDNA with nanodiamonds materials was carried out by the method as described in [3]. The experiments with viruses and nanodiamonds materials were conducted at 4-37°С during 10-20 min.…”

“…Influenza viruses were chosen for this investigation for their widespread presence around the world and a critical role in infecting birds and mammals. The main ways of transmission of influenza A and B viruses are airborne way and water way (for influenza bird viruses).This study continues the series of our works devoted to the search of effective sorbents of different origin for viruses and other nano-sized biological objects [3,4].…”

Исследование Конкурентной Сорбции Вируса Гриппа И Бактерий На Полимерные Материалы

“…Адсорбционный метод. Сорбцию биологических объектов на полимерные композиты проводили по методу, приведенному в работе [14]. После контакта биологических объектов с полимерами образованные в водных растворах комплексы (сорбент+биологический объект) осаждали из растворов при низкоскоростном центрифугировании при 3000 об./мин.…”
