NANOTEXTILES MODIFIED WITH PHTHALOCYANINE DERIVATIVES, PHOTODYNAMIC ACTIVITY AGAINST GRAM-POSITIVE BACTERIA

The following derivatives of phthalocyanine (Pc) were synthesized: HOAlPc (SO 3H) 2, ZnPc (OC 2H4N + CH 3)4 I 4, ZnPc(SO 3H) 0-1 (SO 2NHCH 2 CH 2N(C 2H5)2)1-3, HOAlPc(SO 3H) 0-1(SO 2NHCH 2CH 2NH CH 2CH 2OH) 1-2, and Ag 2Pc These phthalocyanine derivatives were incorporated into polyurethane solutions and subsequently electrospun into nanofibrous layers. Thus, nanotextiles containing 0,1 and 1 weight per cent of phthalocyanine derivatives were prepared. Photodynamic bactericidal action of nanotextile samples modified with the particular phthalocyanines were tested by exposing to the daylight and in the dark, respectively, by using of Gram-positive bacteria Staphylococcus aureus. All the samples of nanotextile performed antimicrobial effect. The best results were obtained with the nanotextile sample modified with ZnPc (OC 2H4N + CH 3)4 I 4
