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 ... -
One-step preparation of multifunctional chitosan microspheres by a simple sonochemical method
(2010)
Article
Restricted access - publisher's policyChitosan is a biodegradable natural polymer with great potential for pharmaceutical applications due to its biocompatibility, high charge density, nontoxicity, and mucoadhesion properties. Processing techniques for the ... -
One-step sonochemical preparation of redox-responsive nanocapsules for glutathione mediated RNA release
(Royal Society of Chemistry, 2014-07-09)
Article
Restricted access - publisher's policyEfficient RNA delivery to targeted cells requires the use of stable interactive carriers that provide RNA protection during the extracellular transit and trigger release once internalised. One strategy to avoid the premature ... -
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 ... -
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 ...
