Triplet-Triplet Annihilation Upconversion in Water Environment: Biocompatible and Non-invasive All-optical Temperature Sensing for Living Objects

Busko D., Dimitrova R., Turshatov A., Avlasevich Y., Landfester K., Baluschev S., Max Planck Institute for Polymer Research, DE

A realistic temperature sensing alternative for life-science objects could be the process of triplet-triplet annihilation upconversion in water environment (TTA – UC): It is inherently micro-scale sensing techniques – the sensing function is carried out [...]

Continuous Flow Real-Time Pcr Platform for High Throughput Environmental Monitoring

Ray T., Hatch A., Lintecum K., Chao S-H, Youngbull C., Arizona State University, US

We present the design and development of a continuous flow quantitative Polymerase Chain Reaction system, suitable for multi-analyte, high-throughput, semi-autonomous assays. This system operates in a continuous fashion and is able to detect many different [...]

HDCR: A novel method for the diagnostic detection of methylated DNA for blood based cancer diagnostics

Molloy P., Rand K., Ho T., Lindall C., CSIRO, AU

We have developed a novel technique for specific amplification of rare methylated DNA fragments in a high background of unmethylated sequences that avoids the need of bisulphite conversion. The methylation-dependent restriction enzyme GlaI is used [...]

Novel sensing device based on potentiometric measurement for the detection of lithium

Merzouk S., Zine N., Tahajanan M., Agouzoul M., Bausells J., Teixidor F., Jaffrezic-Renault N., Errachid A., Institut des Sciences Analytiques, FR

The therapy of manic depressive psychosis with lithium salts requires periodic measurements of the Li concentration in whole blood, plasma, urine or serum. The analysis is difficult because of the low lithium concentration compared to [...]

Nanofabrication Techniques for Fully Integrated Sensing Platforms

Mujeeb-U-Rahman M., Adalian D., Sencan M., Scherer A., California Institute of Technology, US

Designing small scale integrated systems for sensing and actuation has gained lots of interest in recent years. Currently, subsystems are fabricated separately and then bonded together to form an integrated platform. This poses a fundamental [...]

Magnetization of hydrogel particles: a novel urine tuberculosis antigen test

Paris L., Cox A., Petricoin E., Liotta L., Luchini A., George Mason University, US

This study aims at developing a nanotechnology-based screening test that would reliably detect early stage tuberculosis (TB) infection and discriminate active from latent infections. The use of urine in TB testing has been hampered by [...]

The scavenging of reactive oxygen species and the potential for cell protection by fullerenols with different isoelectric points

Li J., Liu X., He R., Chang Y., Zhang M., Liu X., Jin J., Sun B., Zhao Y., Xing G., Chinese Academy of Sciences, CN

Fullerenols were known as the major water-soluble derivatives of fullerene that possess particular signiﬁcance biological effects such as anticancer active and free radical scavengers. We have reported a novel method for purifying nanoparticles of fullerenols, [...]
