PLGA-PEG multifunctional nanoparticles for simultaneous drug delivery and imaging by MRI and fluorescence microscopy
Fornara A., Chiavarino A., Qin J., Toprak M.S., Muhammed M., YKI, Institute for surface chemistry, SE
In recent years, a lot of effort has been put to develop smart nanocarriers for drug delivery to increase the efficacy of certain therapeutic drugs. Still the main challenge is to integrate the therapeutic function, [...]
Gold nanoparticles as a tool to detect UTI and their cytotoxic effects in DU-145 cells
The abstract includes a brief description of how two different kinds of E.coli can have different binding specificities and detection of such organisms with sugar functionalized nanoparticles can be used as a biodiagnostic technique.
Nanocomposites of Nanocrystalline Cellulose for Biosensors Applications
The development of composite materials is getting increased interest, as they can be a way to achieve adequate sensitivity and stability for biosensors. In this work, we describe the use of a composite material made [...]
Ultralow Detection of Bio-markers using Gold Nanoshells
The focus of this project is to improve the detection of antigen/biomarkers/viral vectors using gold nanoshells (GNS). The assay used in this project is based on aggregation of GNS in presence of antigen or viral [...]
Sample Preparation by On-Chip Dielectrophoretic Separation and Concentration of Viable, Non-Viable and Viable but Not Culturable (VBNC) Escherichia coli
Although bacterial culture remains the gold standard for detection of viable bacteria in environmental specimens, the typical time requirement of twenty-four hours can delay and even jeopardize appropriate determination. In addition, culture is incapable of [...]
A sensing properties study on miniature Au/SnO2 gas sensor for hydrogen sulfide detection
The purpose of this study was to investigate the sensing properties for self-developed hydrogen sulfide gas sensor. In different temperature treatment and Au nano-particles doping ration, the sensitivity and selectivity of Au/SnO2 gas sensor were [...]
A Metallofullerene Nanoparticle Platform for Imaging and Treatment of Glioblastoma Multiforme Tumors
Dorn H.C., Zhang J., Fatouros P., Shultz M.D., Wilson J.D., Virginia Polytechnic Institute and State University, US
Glioblastoma multiforme (GBM) brain tumors occur as masses with infiltrative margins that are extremely invasive. GBMs result in a high recurrence rate with a poor prognosis for patients who are newly diagnosed with only an [...]

Encapsulation of nanoparticles with multifunctional, cross-linkable diblock copolymers for biomedicine
Schmidtke C., Ostermann J., Tran H., Pöselt E., Kloust H., Niehaus J., Becker S., Kreuziger A., Werner K., Pietsch A., Weller H., University of Hamburg, DE
We would like to present a micellular encapsulation method for nanoparticles (quantum dots, iron oxides, gold) which is based on a ligand exchange procedure of native ligands with a prepolymer poly(isoprene)-diethylentriamine (PI-N3) and subsequent ligand [...]
Continuous Sensing of blood by dark-field microscopy and surface-enhanced Raman Spectroscopy
Surface-enhanced Raman spectroscopy (SERS) is a rapid, label-free technique with multiplexing capabilities, making it very relevant for the sensitive real-time detection for biomedical applications , , . Demonstration of in vivo glucose detection with unprecedented [...]
CarouCELL – a novel compact submerged perfusion bioreactor for drug screening and tissue engineering
Development of traditional methods of cell growth and manipulation on 2-dimensional (2D) surfaces, have been shown to be far from optimal for new challenges of tissue engineering and drug screening. This has lead to the [...]
DNA detection using Laser Transmission Spectroscopy
Li F., Mahon A.R., Barnes M.A., Egan S., Feder J., Lodge D.M., Hwang C.-T., Schafer R., Ruggiero S.T., Tanner C.E., University of Notre Dame, US
Laser transmission spectroscopy (LTS) is a new quantitative and rapid technique for measuring the size, shape, and number of nanoparticles in suspension. We report on the application of LTS as a novel detection method for [...]
