TETSUO ; HAMMER, DANIEL A. ; THERIEN, MICHAEL J.Convergent advances in photonics and chemistry are enabling many promising optically based technologies for biomedical imaging and phototherapy.1 Successful clinical application is dependent upon the continuing development of bright, nanometersc[...]texto impreso
En junio del año 2008 se constituye el Gabinete Productivo con el objetivo de mejorar la estructura productiva del país, para lograr un crecimiento económico sustentable con justicia social. En esta segunda etapa se seleccionaron ocho cadenas pr[...]Article : documento electrónico
BOTASINI, SANTIAGO, Autor |Con el avance de la nanotecnología, tanto en el ámbito académico como comercial, ha crecido la necesidad de contar con técnicas y protocolos de caracterización de nanopartículas. Si bien existen varios métodos de medida, el “verdadero” tamaño de[...]texto impreso
Designer variable repeat length polypeptides as scaffolds for surface immobilization of quantum dots
MEDINTZ, IGOR L. ; SAPSFORD, KIM E. ; CLAPP, AARON R. ; PONS, THOMAS ; HIGASHIYA, SEIICHIRO ; WELCH, JOHN T. ; MATTOUSSI, HEIDIWe demonstrate the use of a series of engineered, variable-length de noVo polypeptides to discretely immobilize luminescent semiconductor nanocrystals or quantum dots (QDs) onto functional surfaces. The polypeptides express N-terminal dicysteine[...]texto impreso
PINHO, S., AutorLipid-based structures have been successfully developed for use in micro and nanoencapsulation applications for a long time, especially in the pharmaceutical field, and they include lipid emulsions, lipid nanotubes, liposomes and lipid particles[...]texto impreso
SUSUMU, KIMIHIRO ; UYEDA, H. TETSUO ; MEDINTZ, IGOR L. ; PONS, THOMAS ; DELEHANTY, JAMES B. ; MATTOUSSI, HEIDIWe have designed and synthesized a series of modular ligands based on poly (ethylene glycol) (PEG) coupled with functional terminal groups to promote water-solubility and biocompatibility of quantum dots (QDs). Each ligand is comprised of three [...]Article : documento electrónico
PAULA ENCISO, Autor ; LUCÍA MININI, Autor ; BEATRIZ ÁLVAREZ, Autor ; MARÍA FERNANDA CERDÁ BRESCIANO, Autor |Dentro INNOTEC (No. 7, dic. 2012)El empleo de fuentes renovables de energía resulta de creciente importancia en la actualidad debido al agotamiento de las reservas de combustibles fósiles y a los daños medioambientales que estos causan. La posibilidad de utilizar la energía sol[...]texto impreso
Luminescent semiconductor quantum dots (QDs) have great potential for use in biological assays and imaging. These nanocrystals are capped with surface ligands (bifunctional molecules, amphiphilic polymers, phospholipids, etc.) that render them h[...]texto impreso
