Molecular Assembly and Self‐Assembly^a: Molecular Nanoscience for Future Technologies

Abstract

In this review the emerging science of single molecules is discussed in the perspective of nanoscale molecular functions and devices. New methods for the controlled assembly of well-defined molecular nanostructures are presented: self assembly and single molecular positioning. The observation and selective modification of conformation, electronics, and molecular mechanics of individual molecules and molecular assemblies by scanning probes is demonstrated. To complement this scientific review, some of the possible consequences and visions for future developments are discussed, as far as they derive from the presented systems. The prospects of nanoscale science to stimulate technological evolution are exemplified.

Global Gene Response in Saccharomyces cerevisiae Exposed to Silver Nanoparticles

“…This makes them exhibit unique properties such as increased catalytic activity due to morphologies with highly active facets [1,2]. Nanomaterials, such as nanotubes, nanowires, fullerenes, and quantum dots, have received heavy attentions for their possible enormous applications [3]. Despite of the wide application of these nanomaterials, there is a serious concern regarding the impacts of manufactured nanomaterials on human health and the environment.…”

Cadmium telluride quantum dot nanoparticle cytotoxicity and effects on model immune responses toPseudomonas aeruginosa

“…Structurally, QDs are composed of a metal core that determines their colour, an inorganic shell that helps to enhance stability and brightness, and a polymer layer or functional group that enhances water solubility and conjugation capacity (Michalet et al 2005). The unique electrical and optical properties of these NPs make them useful materials for microelectronics and biomedical research (De Wild et al 2003). QDs containing cadmium telluride (CdTe-QDs) offer great potential in therapeutic targeting and in medical and molecular imaging due to their spectral properties such as broad absorption, narrow emission and photostability (Chan et al 2002; Gao et al 2004; Scherer et al 2002).…”
