Photocurable Composite with Antimicrobial Activity for Wound-Healing

Chang M-H, Ding F.-C., Ju W.-Y., Lai P.S., National Chung Hsing University, TW
To develop an appropriate approach that can accelerate the wound healing rate or prevent other microorganisms contamination is necessary for wound healing. In this study, the combination of antimicrobial activity and photodynamic antimicrobial chemotherapy of [...]

Assessing the Antimicrobial Activity of Silver Nanoparticles Leached from Medical Devices

Casey B.J., Dair B.J., U.S. Food and Drug Administration, US
This work focuses on characterization the leachables released from substrates, e.g. medical devices, containing silver nanoparticles. Furthermore, antimicrobial experiments were conducted to determine how the structure of a silver nanoparticle impact antimicrobial activity. Proper characterization [...]

Nanoencapsulated Drug-Carrying System for Photodynamic Antimicrobial Chemotherapy (PACT)

Kalapala G.K.M., Fu P.K.-L., Governors State University, US
Chronic wounds are considered as a pandemic health problem. Approximately 1% to 2% of the population in developing countries has experienced a chronic wound during their lifetime. In the United State States,the expense of treating [...]

Nanogold and Nanosilver Wool: New Products for High Value Fashion Apparel and Functional Textiles

Johnston J., Burridge K., Kelly F., Small A., Victoria University of Wellington, NZ
ORAL We have developed a new proprietary nanotechnology and product suite of high value textiles involving the use of nanogold and nanosilver as colourants and functional components in wool. This innovatively links the high value [...]

Nanogold and Nanosilver Plastics

Pobedinsky M., Johnston J., Victoria University of Wellington, NZ
We present the innovative development of new plastic materials functionalised by nanogold and nanosilver entities which exhibit anti-microbial and catalytic effects for applications such as air and water filters, membranes, protective textiles, wound dressings and [...]

Developing a Strategy for the Spatial Localisation and Autonomous Release of Silver Nanoparticles within Smart Implants

Newton L.A.A., Sharp D.G., Leslie R., Davis J., Nottingham Trent University, UK
A novel approach to the controlled release of silver nanoparticles from a solid state repository within microdevice/micro fluidic architectures is presented. The dynamics of their formation, mechanism and influence on particle formation and release characteristics [...]

Nano Silver – Why It is so Hot Now?

Lem K.W., Haw J.R., Lee D.S., Brumlik C., Sund S., Curran S., Smith P., Brauer S., Schmidt D., Konkuk University, KR
It has been known for centuries that silver has an antiseptic effect. In ancient times, many Greeks used silver vessels for drinking water storage. Koreans have also chosen silver to make their metal chopsticks. Recently, [...]

Effect of Medical Device Substrate Material on Nanoparticulate Silver Efficacy

Dair B.J., Kennedy K.M., Casas R.S., FDA, US
Silver is one of the oldest known natural antimicrobial materials, the active form being the Ag+ ion, which disrupts critical cell functions in bacteria. Reducing the size of silver particles to the nano-scale regime increases [...]

Poly(acrylic) acid-coated Silver Nanoparticles for Antibacterial Textile Finishing

Falletta E., Bonini M., Fratini E., Lo Nostro A., Lo Nostro P., Becheri A., Lo Nostro A., Lo Nostro P., Baglioni P., University of Florence, IT
The synthesis of silver nanoparticles was obtained through two different methods and using different poly(acrylic) acids as templating agents. Cotton, wool, and polyester fabrics were treated with the nanoparticles, and their antimicrobial performances were tested [...]

Photoactive titania and nanoparticulate silver-titania composite thin films as potent antimicrobial coatings

Page K., Parkin I.P., Wilson M., University College London, UK
Nanocrystalline titania (anatase) and Ag-doped titania (anatase) coatings were prepared on glass microscope slides by a sol-gel dip-coating method. The resultant coatings were characterised by X-ray diffraction, XANES, Raman, SEM/WDX, XPS and UV visible techniques [...]
