Resumen:
In
1959 the brilliant scientist Richard Feynman postulated at the American
Physical Society some ideas about manipulation of individual atoms,
miniaturization of computers, and development of better techniques and
machinery for viewing the tiniest of details. This marked a turning
point in science, which has since then turned towards miniaturization.
Feynmans ideas were later realized with the invention of the scanning
tunneling microscope (STM) in 1981, as a tool to manipulate atoms or
molecules, leading to the famous word Nanotechnology. Currently, two
main approaches are used in nanotechnology: one is a "bottom-up"
approach where devices are built from atomic or molecular components
which assemble themselves chemically; the other is a "top-down"
approach where nanodevices are constructed from larger entities without
atomic-level control. Among such nanodevices we can find: nanoclusters,
nanowires, colloidal nanoparticles, nanotubes, nanodots, nanogears,
molecular conductors and many other tiny things within the nanometer
scale. The fabrication of this kind of nanodevices, followed by
intensive research an rigorous study about their applicability to
future technologies has become the main challenge for many scientists
all around the world. Application of these nanodevices depends on two
factors. Firstly, on the thermodynamic stability of the structures
generated, and secondly on the costs of producing these nanodevices in
large scale. This book includes seven reviews written by experts in the
field showing recent advances in the field of nanoscience. The topics
covered are: polymer nanosensors, molecular nanodevices and metal
nanowires, synthesis and characterization of metallic nanoparticles in
solution, nanoelectrochemistry, and nanosolvatation effects on
bio-active molecules. Since many of these topics represent cutting edge
research developed in recent years, we expect this book to be useful
for scientists working in Nanoscience.
