Inducing Polymer Interphase Formation in the Composite at Low Nano-Carbon Loading

Song K., Minus M.L., Northeastern University, US

The nano-carbons used in this work are layered carbon nano-chips that exhibit platelet morphology and are able to slide with respect to each other. Both filled and unfilled poly(vinyl alcohol) (PVA) fibers were studied to [...]

Titania Nanotubes for Separation Applications

Panaitescu E., Ghosh M., Menon L., Northeastern University, US

We investigated the application of titania nanotubes arrays in the form of powders and membranes for water filtration and separation, and for employment in high-performance liquid chromatography. Such membranes have been successfully employed in photocatalytic [...]

Prostate Cancer-Specific Drug Delivery and Imaging System: Design, Synthesis, and Characterization of Multi-functional AuNPs

Dao K-L, Northeastern University, US

A multifunctional gold nanoparticulate (mfAuNPs) drug delivery system that is specific for prostate cancer therapy will be presented. A synthetic modular approach is established to prepare-a)a prostate specific membrane antigen (PSMA) ligands for targeting the [...]

Label-free Raman Micro-Spectral Imaging of the Microenvironment of PANC-1 Spheroids

Chernenko T., Shah R., Zuser E., Diem M., Amiji M., Northeastern University, US

Spheroids are 3D tumor models, which reflect diverse properties of the growing tumor. Due to its avascular microenvironment, initial tumor growth patterns as well as subsequent tumor-core biochemistry may be studied in depth, from which [...]

Gene Delivery and Transfection in Human Pancreatic Cancer Cells using Epidermal Growth Factor Receptor-Targeted Gelatin Nanoparticles

Xu J., Amiji M., Northeastern University, US

More than 32,000 patients are diagnosed with pancreatic cancer in the United States per year and the disease is associated with very high mortality. Although gene therapy has tremendous promise, the major challenge has been [...]

Highly Organized Two and Three Dimensional Singlewalled Carbon Nanotubes-Polymer Hybrid Architectures

Li B., Hahm M.G., Kim Y.L., Kar S., Jung Y.J., Northeastern University, US

We present a new class of highly organized SWCNTs network-polymer hybrid structures, by incorporating horizontally and vertically aligned SWCNTs in desired locations, orientations and dimensions on/inside flexible polymer matrices forming mechanically and electrically robust unique [...]

Morphological Studies on Nano-Neuronal Interactions

Islam A., Menon L., Northeastern University, US

Nanostructures are expected to play a key role in the fundamental investigation of neuronal activity at the nanoscale level. Neurons are complex structures with feature sizes ranging from the millimeter to micron to nanoscale regimes. [...]

Environmental and Economic Assessment of Nano-Fabrication Processes of Memory Devices

Dahlben L., Isaacs J.A., Northeastern University, US

The unique mechanical, electronic, and non-volatility of carbon nanotubes (CNT) have significant potential to replace current silicon-based switches. However, before fully integrating CNT switches into the semiconductor industry, the production costs and environmental impacts associated [...]

Design and implementation of silicon-based optical nanostructures for integrated photonic circuit applications using Deep Reactive Ion Etching (DRIE) technique

Selvarasah S., Banyal R., Casse B.D.F., Lu W.T., Sridhar S., Dokmeci M.R., Northeastern University, US

Photonic crystals (PhC) are artificially engineered periodic structures capable of manipulating and shaping optical signals. Nanoscale photonic crystals is expected to add new functionalities to the next generation of optical integrated circuits by providing novel [...]
