Epidermal Growth Factor Receptor-Targeted Engineered Gelatin Nanovectors for Gene Delivery and Transfection

Magadala P., Amiji M., Northeastern University, US

Purpose: Over 80% of human pancreatic cancer expresses epidermal growth factor family of receptors on the cell surface. In this study, we have examined the potential of EGFR-targeted gelatin-based engineered nanovectors (GENS) for plasmid DNA [...]

Nanoparticle Measurement by Spectroscopic Mie Scattering

Trutna R., Liu M., Chamberlin D., Hadley J., Agilent Technologies, US

We present a spectroscopic technique for measuring particle size. The technique utilizes a UV-Visible spectrophotometer to measure the attenuation spectrum of a particle dispersion due to scattering. Using the Mie scattering theory, we compute the [...]

Ultrasonic Pulsed Doppler (USPD): A Novel Ultrasonic Method for Characterizing Suspensions of Nanoparticles

Africk S.A., Colton C.K., Prodyne Corp., US

This paper describes a novel means for particle characterization, the Ultrasonic Pulsed Doppler (USPD) system. This system uses a single transducer to measure ultrasonic backscatter from moving particles to perform measurements of particle concentration, size [...]

An Embedded Atom Method for Alloy Nanoparticles

Shan B., Hyun J., Wang L., Yang S., Kapur N., Nicholas J.B., Nanostellar Inc., US

We present the development and application of a high-accuracy embedded atom method (EAM) potential for the simulation of metal alloy nanoparticles. The potential was parametrized by a large set of density functional theory (DFT) calculations [...]

Non-destructive 3D Imaging of Nano-structures with Multi-scale X-ray Microscopy

Wang S., Lau S.H., Tkachuk A., Druewer F., Chang H., Feser M., Yun W., Xradia, Inc., US

X-ray microscopy offers a unique combination of large penetration depth, high resolution, and high sensitivity to elemental composition. When combined with computed tomography (CT) techniques, the full three-dimensional structure of a sample can be obtained [...]
