  • Nanotechnology Briefing Paper Clean Water Act

    The purpose of this briefing paper is to evaluate the existing statutory authority under the Clean Water Act (CWA or Act) to regulate nanotechnology and nanoparticles.2 One of the stated national goals of the CWA is the elimination of the discharge of pollutants into the navigable waters. Accordingly, the CWA generally provides the U.S. Environmental Protection Agency (EPA) with authority to ...

  • Preparation and characterisation of 5–fluorouracil containing PLGA nanospheres coated with chitosan, for drug delivery

    The aim of this study was to design a new Drug Delivery System (DDS) based on poly (lactide–co–glycolide) (PLGA) biodegradable nanospheres (NS) coated with Chitosan (CTS), in order to prolong its residence time and to deliver the nanoparticles more specifically to cancer cells. We have tried three methods of incorporation of Chitosan in the nanoparticles, but only one was efficient. The first ...

  • The role of nanotechnology in diabetes treatment: current and future perspectives

    Diabetes is a chronic disease that currently affects approximately 8% of the US population, and that number is expected to increase significantly by the year 2030. It is imperative that effective monitoring and treatment options be available to patients. Nanotechnology is a focal point in diabetes research, where nanoparticles in particular are showing great promise in improving the treatment and ...

  • Nonaqueous synthesis, assembly and formation mechanisms of metal oxide nanocrystals

    Nonaqueous solution routes to metal oxide nanoparticles are a valuable alternative to the well-known aqueous sol-gel processes, offering advantages such as high crystallinity at low temperatures, robust synthesis parameters and avoidance of surfactants in order to control the crystal growth. In the first part of this paper we give an overview of the various solution routes to metal oxides in ...

  • Application of laser-induced breakdown-detection as a sensitive detector for UF membrane surrogate challenge tests

    Characteristics of ultrafiltration membranes with respect to the removal of nanoscale particles can be determined by surrogate challenge tests (SCTs). Key elements of a successful SCT are the selection of a suitable surrogate and a reliable quantification method. A major challenge when using nanoparticles as surrogates is their quantification in the filtrate, since commonly used particle ...

  • A molecular method for assessing the effects of potential contaminants on the rate of zebrafish (Danio rerio) development

    Monitoring expression of the developmentally regulated genes shh, sox2, and tnnt1 by reverse transcriptase polymerase chain reaction (RT‐PCR) allows determination of the rate of embryogenesis in zebrafish (Danio rerio) embryos without direct visual observation. The utility of combining this approach and morphological methods during toxicity studies was demonstrated with embryos developing at ...

  • IEG multi level sampling well (MLSW) case study - IEG Technologie GmbH

    The MLSW-system is used for the recovery of multiple high-quality samples of soil-gas and groundwater from numerous isolated horizons in a single standard borehole. The system is also used to accurately delineate contamination profiles in three dimensions, which is vital or the design, installation and monitoring of remediation systems. MLSWs also can be used for activly dispersing substances ...

  • Silicon optocouplers for biosensing

    Here we review on the fabrication and the bioanalytical applications of a monolithic silicon optocoupler that integrates an array of silicon avalanche diodes as light sources, detectors and silicon nitride optical fibres, all intercoupled through a self-alignment technique. The optocoupler is combined with a microfluidic module that allows for simultaneous real-time sensing of multiple analytes. ...

  • Effect of different water conditions on dissolution of nanosilver

    This study evaluates the time-dependent dissolution of nanosilver (nAg) in common electrolytes and natural waters. nAg was synthesized via Tollens’ method using sodium citrate as stabilizer; its morphology, UV–Vis spectrum, and particle size were characterized. The dissolved silver was monitored over time using filtration, centrifugation, and inductively coupled plasma atomic ...
