Researches concerning the development of polymer biocides represent a great challenge for both academic world and industry. This review will cover most recent advances in antimicrobial polymers for textile coating and finishing. Methods of synthesis, application and grafting of such polymers on textile substrates will be illustrated. Biocidal performances and stability (i.e. fastness to washing...

OBJECTIVES To evaluate the in vitro antibacterial activity of a silver-impregnated coating against a biofilm-forming strain of methicillin-resistant Staphylococcus pseudintermedius (MRSP). METHODS A clinical MRSP isolate sourced from a failed canine knee implant was evaluated for biofilm production and used in the present study. Using a standard test method and a clinically approved titanium ...

BACKGROUND Surgical sutures can promote migration of bacteria and thus start infections. Antiseptic coating of sutures may inhibit proliferation of adhered bacteria and avoid such complications. OBJECTIVES This study investigated the inhibition of viable adhering bacteria on novel antimicrobially coated surgical sutures using chlorhexidine or octenidine, a critical factor for proliferation at...

BACKGROUND Postoperative infection associated with implants remains a serious complication in orthopedic surgery. Several biomaterial surface treatments have been proposed as a means of reducing the incidence of implant-associated infections. In this study, a clinical trial was performed using an iodine-supported titanium that suppresses the microbial activities. METHODS A total of 222 patien...

INTRODUCTION: Orthopaedic prostheses implantation is an invasive surgical procedure, with an increased risk for post-operative infections. Since the life span and quality of these implants is improving and more prostheses are implanted every year, the incidence of post-operative infections will increase. Most implants are based on titanium or nickel-chromemolybdenum alloys, while their overall ...

In the present study, biological hydroxyapatite (HA) was obtained from bovine bones through a thermal process. A total of 0% and 1% of silver nanoparticles (Ag-NPs) synthesized from Opuntia ficus (nopal) were added to the biological hydroxyapatite coatings using an atmospheric plasma spray (APS) on a Ti6Al4V substrate. Following this, its antimicrobial efficiency was evaluated against the follo...

Nosocomial infections are a major clinical concern, posing great risks for patients and rising costs health services providers. This work aims at developing hard, wear resistant coating, whose antimicrobial properties shall prevent the transmission of infections. TiN coatings deposited by Physical Vapour Deposition, PVD, with different Ag contents have been studied, especially in relation to ha...

hLF1-11 (GRRRRSVQWCA) is an antimicrobial peptide (AMP) with high activity against methicillin-resistant Staphylococcus aureus (MRSA), the most prevalent species in implant-associated infection. In this work, the effect of the surface immobilization on hLF1-11 antimicrobial activity was studied. Immobilization was performed onto chitosan thin films as a model for an implant coating due to its r...
