the usage of antimicrobial materials for coating meat products, in addition to reducing the microbial population and increase of the quality safety of products, be greatly reduced usage of nitrites as preservatives and synthetic carcinogens. compounds that have antimicrobial activity can be mixed, stabilized or incorporated with edible coatings. spices and vegetable extracts are also a group of...

Methicillin-resistant Staphylococcus aureus (MRSA) has become an important cause of hospital-acquired infections worldwide. It is one of the most threatening pathogens due to its multi-drug resistance and strong biofilm-forming capacity. Thus, there is an urgent need for novel alternative strategies to combat bacterial infections. Recently, we demonstrated that a novel antimicrobial surface coa...

This paper demonstrates the effectiveness of a new antimicrobial suture coating. An amphiphilic polymer, poly[(aminoethyl methacrylate)-co-(butyl methacrylate)] (PAMBM), inspired by antimicrobial peptides, was bactericidal against S. aureus in time-kill experiments. PAMBM was then evaluated in a variety of polymer blends using the Japanese Industrial Standard (JIS) method and showed excellent...

it is possible to develop new biodegradable active packaging by coating biopolymers on paper-based packaging material and also incorporating proper antimicrobial agents into coating structure. in this study bacterial contamination of two commercial cardboard were evaluated.in order to manufacture an appropriate antibacterial packaging material, coating of chitosan-poly vinyl alcohol blends with...

Prevention of implant-associated infections has been one of the main challenges in orthopaedic surgery. This challenge is further complicated by the concern over the development of antibiotic resistance as a result of using traditional antibiotics for infection prophylaxis. The objective of this study was to develop a technique that enables the loading and local delivery of a unique group of ca...

The development of antimicrobial coatings for footwear components is of great interest both from industry and consumer's point of view. In this work, antimicrobial leather materials were developed taking advantage of chitosan intrinsic antimicrobial activity and film forming capacity. Considering the specificities of the leather tanning industry, different coating technologies, namely drum, cal...

during storage of eggs, unfavorable changes occur due to exertion of co2 and water vapor from through of crust pinholes. one of the practical methods for preventing or reducing these changes is to use biopolymer-based coatings. in this research, five coating solutions based on carboxymethyl cellulose (cmc) and glycerol as plasticizer, oleic acid (1 and 2% v/v) and antimicrobial agents (potassiu...

The prevention and control of peri-implantitis is a challenge in dental implant surgery. Dental implants with sustained antimicrobial coating are an ideal way of preventing peri-implantitis. This study reports development of a non- immunotoxicity multilayered coating on a titanium surface that had sustained antimicrobial activity and limited early biofilm formation. In this study, the broad spe...

Bacterial colonization on implant surfaces and subsequent infections are one of the most common reasons for the failure of many indwelling devices. Several approaches including antimicrobial and antibiotic-eluting coatings on implants have been attempted; however, none of these approaches succeed in vivo. Here we report a polymer brush based implant coating that is non-toxic, antimicrobial and ...

Investigating the interaction patterns at nano-bio interface is a key challenge for safe use of nanoparticles (NPs) to any biological system. The study intends to explore the role of interaction pattern at the iron oxide nanoparticle (IONP)-bacteria interface affecting antimicrobial propensity of IONP. To this end, IONP with magnetite like atomic arrangement and negative surface potential (n-IO...
