“…The composites were characterized by a complex of physio-mechanical and biological-biochemical tests. The main purpose of the presented paper is to assess the major blood coagulation parameters of the PLA-Zn composites, namely the Activated Partial Thromboplastin Time (aPTT) and Prothrombin Time (PT) [118].…”

This article presents the biochemical properties of poly(lactide)-zinc (PLA-Zn) composites obtained by DC magnetron sputtering of zinc onto melt-blown nonwoven fabrics. The biochemical properties were determined by the evaluation of the activated partial thromboplastin time (aPTT) and prothrombin time (PT). The antimicrobial activity of the PLA-Zn samples was additionally tested against representative Gram-positive and Gram-negative bacteria strains. A structural study of the PLA-Zn has been carried out using specific surface area and total pore volume (BET) analysis, as well as atomic absorption spectrometry with flame excitation (FAAS). PLA-Zn composites exhibited an antibacterial effect against the analyzed strains and produced inhibition zones against E. coli and S. aureus. Biochemical investigations revealed that the untreated PLA fibers caused the acceleration of the clotting of human blood plasma in the intrinsic pathway. However, the PLA-Zn composites demonstrated significantly different properties in this regard, the aPTT was prolonged while the PT was not altered.

The paper presents the study concerning the preparation and physio-chemical and biological properties of wool–copper (WO-Cu) materials obtained by the sputter deposition of copper onto the wool fibers. The WO-Cu material was subjected to physio-chemical and biological investigations. The physio-chemical investigations included the elemental analysis of materials (C, N, O, S, and Cu), their microscopic analysis, and surface properties analysis (specific surface area and total pore volume). The biological investigations consisted of the antimicrobial activity tests of the WO-Cu materials against colonies of Gram-positive (Staphylococcus aureus) bacteria, Gram-negative (Escherichia coli) bacteria, and fungal mold species (Chaetomium globosum). Biochemical–hematological tests included the evaluation of the activated partial thromboplastin time and pro-thrombin time. The tested wool–copper demonstrated the ability to interact with the DNA in a time-dependent manner. These interactions led to the DNA’s breaking and degradation. The antimicrobial and antifungal activities of the WO-Cu materials suggest a potential application as an antibacterial/antifungal material. Wool–copper materials may be also used as customized materials where the blood coagulation process could be well controlled through the appropriate copper content.
