Visible Upconversion in Rare-earth Ion-doped NaYF4 Crystals and Nanocoloids

Patel D.N., Jumper M., Wright III D.M., Sarkisov S., Oakwood University, US

Nano-colloids and nano-crystals doped with rare-earth elements have recently attracted a lot of attention in the scientific community. This attention is due to unique physical, chemical and optical properties attributed to nanometer size of the [...]

Synthesis of Magnetically Sensitive Nanomaterials with Tunable Properties

Ieta A., Patus J., Apenowic J., Marius C., State University of New York at Oswego, US

New magnetic nanomaterials with tunable properties were produced using three procedures. (1) Mixtures of polyvinyl alcohol (PVA) solutions and ferric oxide [3] based ferrofluid were prepared and also electrospun with the purpose of synthesizing magnetic [...]

Multi-functional micelles for the combination of chemotherapy and radiotherapy in hepatocellular carcinoma

Shih Y-H, Peng C.L., Luo T-Y, Shieh M.J., National Taiwan University, TW

Hepatocellular carcinoma is the third leading cause of cancer deaths in worldwide. In this study, multi-functional micelles loaded with doxorubicin (Dox) and labeled with the radionuclide rhenium-188 (188Re) were developed to provide the combination of [...]

Highly Spherical Gold Nanoparticles by Laser Pulse Heating

Cavicchi R.E., Meier D.C., Presser C., Guha S., National Institute of Standards and Technology, US

Methods continue to be developed for improving the size and shape uniformity of Au nanoparticles (NP), however, fabricated NPs tend to be faceted and not highly spherical. We present results that show that the faceted [...]

Synthesis of Micrometric Single Crystalline Magnetite with Superparamagnetic Properties for Biomedical Applications

Chirita M., Kiss M.L., Ieta A., Grozescu I., State University of New York at Oswego, US

There are no reports on the synthesis of single crystalline micrometric magnetite with superparamagnetic behavior. The literature mainly refers to micrometric particles obtained by nanoparticle agglomeration. The major disadvantage of magnetic microparticles composed of clusters [...]

PLA-PEG as a delivery system for a Chlamydia trachomatis subunit vaccine

Dixit S., Singh S.R., Yilma A.N., Agee R., Dennis V.A., Alabama State University, US

We hypothesize that M287 encapsulated in PLA-PEG will provide for its slow controlled release and thus enhance its capacity to induce immune responses in mice.

Multifunctional plasmonic nanoparticles for biomedical applications

Sotiriou G.A., Pratsinis S.E., ETH Zürich, CH

Plasmonic nanoparticles play an important role in biomedical applications today as they can serve as superior optically-stable bioimaging agents, be employed in biosensor devices for the early diagnosis of diseases, and exhibit promising results for [...]

Synthesis of Air-stable Aluminum Nanoparticles capped with 1, 2 -Epoxy-9-Decene/ Methyl Methacrylate and Poly (Methyl Methacrylate)

Patel A., Guliants E.A., Bunker C.E., Jelliss P.A., Buckner S.W., Saint Louis University, US

Aluminum metal, with its light weight, high energy density, and ready availability is particularly valued in energetic application such as fuel additives. Aluminum nanoparticles (Al NPs) offer the advantage of accessing this high energy content [...]

Capping and Passivation of Aluminum Nanoparticles: Aluminum-Induced Alkene Polymerization

Thomas B.J., Lloyd E., Guliants E.A., Bunker C.E., Jelliss P.A., Buckner S.W., Saint Louis University, US

Aluminum nanoparticles (Al NPs) have long been utilized for high-density energy storage and small-scale hydrogen production. The enthalpy of reaction for the formation of aluminum oxide (-1675.7 kJ mol-1) is a major reason for aluminum’s [...]

Polymerization Passivation Strategies for the Stabilization of Energetic Aluminum Nanomaterials

Jelliss P.A., Thomas B.J., Patel A., Lloyd E., Guliants E.A., Bunker C.E., Buckner S.W., Saint Louis University, US

We are developing aluminum nanoparticle (Al NP) passivation strategies based on our established protocols for polymerization of epoxide molecules with a view to fabricating air-stable Al NPs with long shelf-lives. Additionally we have discovered that [...]
