Nanopartikel, Proteine und Nucleinsäuren: Die Biotechnologie begegnet den Materialwissenschaften

Abstract

4257Abbildung 2. Mit konventionellen Top-down-Prozessen sind Strukturgröûen von weniger als ca. 100 ± 200 nm nur unter groûem Aufwand herstellbar, dagegen liegen die Grenzen herkömmlicher Bottom-up-Prozesse im Bereich von ca. 2 ± 5 nm. Wegen ihrer Dimensionen sind zwei Arten von Bausteinen geeignet, um die Lücke zwischen 5 und 200 nm zu schlieûen: biomolekulare Komponenten wie Proteine und Nucleinsäuren und kolloidale Nanopartikel aus Metall oder Halbleitermaterialien.

Studies on 2D hybrid films of half surfactant-covered Au nanoparticles at the air/water interface

“…The assembly of nanoparticles into 2D or 3D superstructures allows the creation of novel materials and devices with potential applications in, for example, optical switches and filters, chemical and biochemical sensors, photoelectronic devices, and templates for ordered microporous materials [3][4][5][6][7][8][9]. A number of assemblies have been extensively studied, including gravity sedimentation [10], electrophoretic deposition [11], electrostatically induced crystallization [12], colloidal epitaxy [13], convective self-assembly [14], and physical confinement [15,16].…”

On‐Chip Integration of Functional Hybrid Materials and Components in Nanophotonics and Optoelectronics

“…Motivation for the use of self -assembly in nanofabrication comes from the observation that many biological structures are assembled by the molecular -level self -assembly [93] . DNA strands [94] , peptides [95] , and viruses [96] are the possible templates on which a signifi cant amount of research work currently continues.…”

Microwave assisted synthesis and characterisation of a zinc oxide/tobacco mosaic virus hybrid material. An active hybrid semiconductor in a field-effect transistor device

“…In recent years, the synthesis and fabrication of bio-inorganic nanostructures have gained tremendous importance for the fabrication of nanoscale devices with defined functional properties [1][2][3]. Significant interest has been dedicated to the generation of multifunctional devices by employing a unique combination of functional biological molecules and inorganic ma-terials.…”
