DNA/RNA Purified Single Walled Carbon Nanotubes on Self-Assembled Networks

Jeynes J.C.G., Mendoza E., Chow D., McFadden J., Silva S.R.P, University of Surrey, UK

Carbon Nanotubes (CNT) have attracted a huge interest in the research community to their extraordinary properties. However, the production methods, specially in the case of single walled CNT (SWNCT), also create a high number of [...]

Synthesis and Properties of Magnetic Nanoparticles with Potential Applications in Cancer Diagnostic

Neamtu J., Jitaru I., Malaeru T., Georgescu G., Kappel W., Alecu V.-V., National Institute for Research, RO

The size, shape and composition of magnetic nanoparticles are very attractive for diagnostic tools of cancer tumors and targeting treatment in HIV infection. The goal of this paper is the preparation from colloidal solutions of [...]

Water-Soluble, Carboxyl-Modified Silicon Nanoparticles

Lee S., Cho W-J, Korea Institute of Science and Technology, KR

Since silicon has both the well-known chemistry and the industrial benefits of non-toxic and low cost, an interest in Si nanoparticles has rapidly increased. We will discuss a practical surface modification of Si nanoparticles prepared [...]

Formation of Polymer Nano-particles in Supercritical Fluid Jets

Gokhale A.A., Khusid B., Dave R.N., Pfeffer R., New Jersey Institute of Technology, US

The supercritical antisolvent process is an emerging technology for the production of micro- and nanometer-sized particles for a wide variety of bio-medical pharmaceutical applications. In this method, an organic liquid solution of the compound of [...]

Self-Assembly of Fluorescent Silica (glass) Beads

Kievesky Ya., Sokolov I., Clarkson University, US

We report self-assembly of fluorescent silica (glass) bids. The bids are a few microns glass nanoporous particles which contain florescent dyes imbedded in the pores. The pores are self-closed, so the dye does not leak [...]

Fluorescent Silica Beads for Detection of Cervical Cancer

Iyer S., Kievesky Ya., Woodworth C.D., Sokolov I., Clarkson University, US

We present the use of self-assembled fluorescent silica (glass) bids for detection of cervical cancer. The cells from three different individuals (3 normal and 3 tumor) were tested for affinity by using the bids, a [...]

Liposome Encapsulation of Fluorescent Nanoparticles: Quantum Dots and Silica Nanoparticles

Chen C-S, Yao J., Durst R.A., Cornell University, US

Quantum dots (QDs) and silica nanoparticles (SNs) are new classes of fluorescent probes that overcome the limitations encountered by organic fluorophores in bioassay and biological imaging applications. We encapsulated QDs and SNs into liposomes by [...]

Labeling and Imaging of Human Mesenchymal Stem Cells with Quantum Dot Bioconjugates during Proliferation and Osteogenic Differentiation in Long Term

Shah B., Clark P.A., Stroscio M., Mao J.J., University of Illinois at Chicago, US

Tissue engineering approaches have the potential to repair damaged bone using a patient’s own mesenchymal stem cells (hMSCs). The objective of this study was to determine the feasibility of long-term labeling of hMSCS with semiconductor [...]

Quantum Dot-Mediated Separation-Free Assay for Point Mutation Detection

Yeh H.C., Ho Y.P., Wang T.H., John's Hopkins University, US

We describe a novel semiconductor quantum dot (QD)-based biosensing assay for single nucleotide polymorphism (SNP) detection. By integrating a QD-mediated dual-color fluorescence coincidence detection method with oligonucleotide ligation assay (OLA), we have achieved rapid SNP [...]
