nano-oxygen carrier for machine perfusion organ storage

Srinivas G., TDA Research Inc., US

TDA Research, Inc. (TDA) and its collaborator Southwest Research Institute (SwRI) are developing a perfusion system for the salvage and repair of trauma injured tissue. Machine perfusion is an emerging preservation modality for tissue preservation [...]

Novel fatty-acid assisted co-precipitation method for synthesis of the SrAl2O4:Eu2+, Sm3+ storage phosphor nanoparticles

Levchuk I., Römling L., Steimle M., Osvet A., Batentschuk M., Winnacker A., Brabec C.J., University of Erlangen-Nuremberg, DE

Biological and medical imaging is a key-stone for in-vivo and in-vitro monitoring necessary for basic research and for medical diagnostics. Inorganic nanoparticles have already been established as fluorescence markers due to their high stability and [...]

Synthesis of highly efficient ZnAgInS-ZnInS/ZnS quantum dots and application for down-converted LEDs

Oh J.H., Lee K.N., Lee S., Kim S., Lee K.N., Lee S., Do Y.R., Kookmin University, KR

This study introduces innovative exothermic reaction assisted synthetic method for highly efficient green emitting ZnAgInS-ZnInS/ZnS quantum dots (QDs) by simply adding excess amounts of Zn precursors (Zinc acetate dehydrate, ZAD) and application for down-converted light [...]

Photodegradation of Organic Dyes using CdSTe Quantum Dots

Aviles-Martin C., Alamo-Nole L., Pontifical Catholic University of Puerto Rico, US

The inappropriate disposal of organic dyes used in a variety of industrial applications has become the contamination source of many water sources. This environmental problem has created the need for more effective and simple methods [...]

Nano-engineering Core/Shell Quantum Dots for Ultimate Utility in Light-emission Applications

Htoon H., Hollingsworth J.A., Los Alamos National Laboratory, US

Quantum-confinement effects have been used for decades to tune semiconductor opto-electronic properties. More recently, particle-size control as the primary means for properties control has been succeeded by nanoscale hetero-structuring. In this case, the nanosized particle [...]

Infrared active nanoprobes for bio-medical imaging based on inorganic nanocrystals

Podhorodecki A., Banski M., Noculak A., Golacki L., Krajnik B., Woznica H., Lesiak A., Sojka B., Wroclaw University of Technology, PL

Optically active inorganic nanocrystals (NCs) (quantum dots, QDs) are recently widely used in research related to bio-medicine as efficient in vivo and in vitro optical markers but also as building blocks in bio-sensors. However, even [...]
