Stable Isotope Tracing – a way forward for Nanotechnology?

Gulson B., Wong H., McCall M., Danon S., Greenoak G., Trotter J., Casey P., Stauber J., Commonwealth Scientifc and Industrial Research Organisation, AU

Numerous publications and reports have expressed health and safety concerns about the production and use of nanoparticles, especially in areas of exposure monitoring, personal use, and environmental fate and transport. We suggest that stable isotopic [...]

Adsorption/Desorption of Cd by Titanium Dioxide Nanoparticles and Sediment Particles as well as Their Facilitated Bioaccumulation of Cd into Carp

Zhang X., Chen Y., Sun H., Crittenden J.C., Arizona State University, US

There are increasing concerns about the health and environmental impact of nanomaterials. The study of Sun et. al 2006 provided the evidence of facilitated bioaccumulation of As(V) in carp in the presence of titanium dioxide [...]

Detection, Measurement and Toxicology of Semiconductor Nanocrystals in Ceriodapnia dubia

Ingle T., Hannigan R., Buchanan R., Bouldin J., Arkansas State University, US

Engineered nanomaterials differing in size, shape, surface area and composition are used in research, industrial, and consumer applications. Because of their unique structure and size the need exists for toxicological profiles of nanoparticles as a [...]

Development of SERS Spectroscopy for Routine and Rapid Identification of Escherichia Coli and Listeria Monocytogenes on Ag Colloidal Nanoparticles

Chen Y-R, Liu Y., Nou X., Chao K., USDA/ARS Beltsville Agricultural Research Center, US

Rapid, accurate, and preferably routine methods for the identification of foodborne bacteria are increasingly important, because of bio- /agro-terrorism threats, public health concerns, and economic loss. Conventional detection of bacteria is time-consuming, requiring 5-7 days, [...]

Utilizing Silver and Gold Nanoparticles for Investigation of Bacterial Cell Wall Biochemical Structure

Culha M., Kahraman M., Yazici M.M., Sahin F., Yeditepe University, TR

Understanding fundamental principles of living systems in their natural environment is always a challenge for scientists. The desire to design and construct novel diagnostic tools makes this understanding a significant prerequisite. Due to its “fingerprinting” [...]

Stable Self-Assembled Monolayers for sensitive biosensor interfaces

Jans H., Jans K., Jans H., Jans K., Bonroy K., Frederix F., Reekmans G., Maes G., Borghs G., IMEC, BE

One of the most important requirements for making advanced biosensors and biochips is the attachment of biological receptors onto a solid support. For this reason, it is important to construct a stable and well-characterized interface [...]

nanometric thinfilm sensor

Bauer M., Putz E.M., Pittner F., University of Vienna, AT

We want to present an optical thin film sensor chip able to detect the decay of food through a specific color change. The design of the chip relates to a phenomenon, the so called “anomalous [...]

Biodegradable Nanoparticles Effect on Drug Delivery System

Kim B.G., Kang I.J., Kyungwon University, KR

Recently, it is very mortal that so many percentages of people get infected with chronic hepatitis as increasing trend and consequently leaded to the death because of a complication arises of cirrhosis and liver cancer. [...]

Mechanism of Action and Surfactant Influence During Chemotherapy of Brain Tumour Using Doxorubicin-Loaded Poly(Butyl Cyanoacrylate) Nanoparticles

Petri B., Bootz A., Khalanski A., Hekmatara T., Müller R., Kreuter J., Gelperina S., Moscow Medical Academy, RU

Polysorbate 80(Tween® 80)-coated poly(butyl cyanoacrylate) nanoparticles have been shown to enable the transport of doxorubicin (DOX) across the blood-brain barrier (BBB). This formulation produced a high antitumoral effect in an orthotopic model of the very [...]
