Nanoparticle Synthesis & Applications

A Novel Pulsed High-density Plasma Process for Nanoparticle Synthesis

Helmersson U., Söderström D., Pilch I., Pillay S., Brenning N., Linkoping University, SE

Today there are various plasma techniques where material is sputtered and used to synthesize nanoparticles. However, we have been unable to identify anyone ionizing the sputtered material in such a process. The advantage of ionizing [...]

Flame Deposition of Superhydrophobic and Superhydrophilic Nanoparticle Coatings on Paperboard Materials

Aromaa M., Haapanen J., Teisala H., Tuominen M., Stepien M., Saarinen J.J., Toivakka M., Kuusipalo J., Mäkelä J.M., Tampere University of Technology, FI

Liquid Flame Spray is one of the flame aerosol methods for the nanoparticle synthesis. Here, it is used in depositing the particles directly on a moving roll-to-roll substrate. The deposition process is performed in a [...]

Continuous synthesis of highly-specific silicon nanopowder on the pilot-plant scale

Hülser T., Schnurre S.M., Schulz C., Wiggers H., Institute of Energy and Environmental Technology (IUTA), DE

In this work we present the formation process of crystalline and amorphous nanostructured silicon made from a continuously operating hot-wall reactor synthesis process. In this reactor, silicon particles are synthesized at variable operating conditions varying [...]

Pilot-scale Nanoparticle Manufacture

Wegner K., Grohn A., Multer S., ETH Zürich, CH

A fully automated pilot plant for nanoparticle manufacture by flame spray pyrolysis is presented that allows continuous production of nanopowders at rates up to 500 g/h. For the example of zirconia the scale-up from the [...]

Synthesis, Characterization and Toxic Metal-Binding Ability of Poly(γ-glutamic acid)-coated Superparamagnetic Nanoparticles

Chen B.H., Inbaraj B.S., Fu Jen University, TW

Superparamagnetic iron oxide nanoparticles (SPIONPs) coated with a non-toxic, edible biopolymer poly(-glutamic acid) (PGA-coated SPIONs) were synthesized by co-precipitation method, characterized and evaluated for their possible toxic metal-binding ability in the treatment of metal intoxication [...]

Stability of Functionalized Magnetic Particles in a Physiologic Fluid

Baca Ramos K., Martínez Pérez C.A., Camacho Montes H., Olivas Armendáriz I., Martel A., García-Casillas P.E., Universidad Autonoma de Ciudad Juarez, MX

Magnetic materials are widely used in biomedical applications such as magnetic separation, magnetic resonance imaging, drug delivery and hyperthermia. In these applications the nanoparticles are functionalized in a core/shell type with polymeric materials which contains [...]

Nanotechnology systems for drug delivery, multi-modal targeting and imaging of tumors

Singh M., Patel A.R., Lim E., Zhang N., Francis K., Safe S., Florida A & M Univeristy, US

Cancer is one of the leading causes of deaths (1.6 million deaths annually) in USA. Despite recent advances in chemotherapy, the survival rates in lung cancer patients are unsatisfactory due to limited efficiency of systemic [...]

Biological synthesis of copper nanoparticles using plant extract

Lee G., Lee H.J., Lee G., Lee H.J., Jang N.R., Yun J.H., Song J.Y., Kim B.S., Chungbuk National University, KR

Copper nanoparticles were biologically synthesized using plant leaf extract as reducing agent. On treatment of aqueous solutions of CuSO4•5H2O with leaf extract (Magnolia), stable copper nanoparticles were formed. UV-vis spectroscopy was used to monitor the [...]

Hydrothermal approach to a carbon graphite encapsulated FeCo nanocrystals for diagnosis, hyperthermia therapy and siRNA delivery

Park J.K., Jung J.J., Subramaniam P., Shah B., Kim C.J., Lee J-K, Lee K.B., Lee J-K, Lee K.B., Korea Research Institute of Chemical Technology, KR

An effective therapeutic approach against cancer requires the combination of several modalities such as chemotherapy, radiation, and hyperthermia. However, the development of multifunctional nanomaterial-based systems that can provide the combined therapeutics and molecular imaging with [...]
