Durable antimicrobial cotton textiles coated sonochemically with ZnO nanoparticles embedded in an in-situ enzymatically generated bioadhesive
(2018-02-14)
Article
Open AccessAn important preventive measure for providing a bacteria-free environment for the patients is the introduction of highly efficient and durable antibacterial textiles in hospitals. This work describes a single step ... -
Enzymatic pre-treament as a means of enhancing the antibacterial activity and stability of ZnO nanoparticles sonochemically coated on cotton fabrics
(2012-03-15)
Article
Restricted access - publisher's policyZinc oxide nanoparticles (ZnO NP’s) are known for their excellent antibacterial properties. This paper describes a method for enhancing the stability and the antibacterial activity of ZnO NPs synthesized and embedded ... -
Hybrid chitosan-silver nanoparticles enzymatically-embedded on cork filter material for water disinfection
(2017-04-05)
Article
Restricted access - publisher's policyMicrobial contamination remains a major challenge in supply of drinking water in developing regions, despite the continuous advances being made in water purification processes. The spread and transmission of pathogens due ... -
Making the hospital a safer place by sonochemical coating of all its textiles with antibacterial nanoparticles
(2015-01-28)
Article
Open AccessThe ability to scale-up the sonochemical coating of medical textiles with antibacterial nanoparticles is demonstrated in the current paper. A roll-to-roll pilot installation to coat textiles was built taking into consideration ... -
Novel lignin-capped silver nanoparticles against multidrug resistant bacteria
(2021-05-04)
Article
Open AccessThe emergence of bacteria resistant to antibiotics and the resulting infections are increasingly becoming a public health issue. Multidrug-resistant (MDR) bacteria are responsible for infections leading to increased morbidity ... -
Simultaneous sonochemical-enzymatic coating of medical textiles with antibacterial ZnO nanoparticles
(2016-03-01)
Article
Open AccessThe antimicrobial finishing is a must for production of medical textiles, aiming at reducing the bioburden in clinical wards and consequently decreasing the risk of hospital-acquired infections. This work reports for the ... -
Sonochemical co-deposition of antibacterial nanoparticles and dyes on textiles
(2016-01-04)
Article
Open AccessThe sonochemical technique has been already proven as one of the best coating methods for stable functionalization of substrates in a broad range of applications. Here, we report for the first time on the simultaneous ... -
Sonochemical coating of textiles with hybrid ZnO/chitosan antimicrobial nanoparticles
(2014-01-09)
Article
Restricted access - publisher's policyTextiles are good substrates for growth of microorg anisms especially under moisture and temperature conditions found in hospitals. Microbia l shedding from the body occurs continuously at contact of the patient with ... -
Sonochemically engineered nano-enabled zinc oxide/amylase coatings prevent the occurrence of catheter-associated urinary tract infections
(Elsevier, 2021-10-26)
Article
Open AccessCatheter-associated urinary tract infections (CAUTIs), caused by biofilms, are the most frequent health-care associated infections. Novel antibiofilm coatings are needed to increase the urinary catheters' life-span, decrease ... -
Tannic Acid NPs - Synthesis and immobilization on to a solid surface in a one – step process and their antibacterial and anti-inflammatory properties
(2013-12-14)
Article
Restricted access - publisher's policyTannic acid nanoparticles were synthesized from an aqueous solution without the use of stabilizers via a sonochemical process. In order to avoid the dissolution of the formed nanoparticles, the sonochemical reaction was ...
