2008-12-01

Resumen en español El mundo llama hoy nanotecnología a la investigación y desarrollo de estructuras y dispositivos en la escala del nanómetro (10-9 m) producto de la manipulación de átomos y moléculas. Dichos elementos tienen aplicaciones en diferentes campos de la investigación, como en la gastrohepatología, donde se adelantan estudios que involucran Nnanomateriales y nanoestructuras como nanopartículas, nanocapas, nanotubos de carbón, puntos cuánticos entre otros, todos ellos r (mas) elacionados con el diagnóstico y terapia de diversas enfermedades gastrointestinales y hepáticas, especialmente neoplasias. De acuerdo con este panorama, en la presente revisión se pretende generar interés por el tópico de la nanotecnología en la comunidad médica. Resumen en inglés The world calls today Nanotechnology to the investigation and development of structures and devices in the nanometer scale (10-9 m), by means of atoms and molecules manipulation. These elements have applications in different investigation fields, like Gastrohepatology, where there are studies that involve Nanostructures and Nanodevices like: Nanoparticles, Nanoshell, quantum dots, and coal Nanotubes, all of them related with the diagnosis and therapy of diverse gastrointe (mas) stinal and hepatic disease, specifically neoplasm. According to panoramic, in this review we pretend to generate interest about nanotechnology in the medical community.

Formation and optical characterization of single InAs quantum dots grown on GaAs nanoholes

Alonso-González, Pablo; Alen, Benito; Fuster, David; González, Yolanda; González, Luisa; Martínez-Pastor, Juan

We present a study of the structural and optical properties of InAs quantum dots formed in a low density template of nanoholes fabricated by droplet epitaxy on GaAs (001). The growth conditions used here promote the formation of isolated quantum dots only inside the templated nanoholes. Due to the g...

The authors have studied the use of antimony for the optimization of the InAs/GaAs(001) self-assembled quantum dot (QD) luminescence characteristics in the 1.3 µm spectral region. The best results have been obtained by capping InAs QDs with 2 ML of GaSb grown on top of a 3 ML GaAs barrier separatin...

We have developed a growth process that leads to the direct formation of self-assembled InAs quantum dots on InP(001) by solid-source molecular beam epitaxy avoiding the previous formation of quantum wires usually obtained by this technique. The process consists of a periodically alternated depositi...
