Bacteria-Enabled Autonomous Drug Delivery Systems: Development, Characterization of Intratumoral Transport and Modeling
… acid) nanoparticles, hereafter referred to as NanoBEADS (Nanoscale Bacteria Enabled Autonomous Drug Delivery System). To this end, a NanoBEADS fabrication procedure that is robust and repeatable was established and a microfluidic chemotaxis-based sorting platform for the separation NanoBEADS …

MODIFICATION OF VESICULAR STOMATITIS VIRUS G PROTEIN FOR TARGETED GENE DELIVERY INTO PSCA-POSITIVE TUMOR CELLS
… used for targeting to PSCA-positive cells using nanobeads. The nanobeads were chemically coupled to antibodies against the epitope in the VSV-G protein and PSCA on the tumor cell. These bispecific nanobeads allowed the recruitment of mutant retroviral particles to the PSCApositive cells. Our …

QCM Aptasensor for Rapid and Specific Detection of Avian Influenza Virus
… QCM sensor to capture the target virus. Magnetic nanobeads (150 nm in diameter) were then added as amplifiers considering its large surface/volume ratio which allows for a higher target molecule binding rate and faster movement. The result showed that the captured AIV caused frequency change, and …

Design and Fabrication of Nanofluidic Systems with Integrated Sensing Electrodes for Rapid Biomolecule Characterization
… biomolecule characterization, negatively-charged nanobeads (20-nm yellow-green FluoSpheres®) were translocated through the nanochannel and their corresponding electrical signatures were measured by the embedded sensing electrodes. The result was in general agreement with the electrical tunneling …

Geometry Dependent Plasmonic Activities of a Self-assembled Hexagonal Lattice and a Periodic Hexagonal Lattice with Gold Nanopillars
… and manipulate light at the nanoscale. Silica nanobeads were used to obtain real values for nanopillar centers which were required to develop a computer algorithm to create replicas of a self-assembled hexagonal lattice. A simulation tool, EM Explorer, was used to study the plasmonic activities …

Characterization of carbon nanoclusters produced by arc-discharge
… stimulates the formation of strings of carbon nanobeads. A growth model for this phenomenon is presented. Finally, the conversion of carbon nanotubes into SiC whiskers is reported. In contrast to the conventional process, starting with nanotubes offers a high purity SiC whisker without any …
