Abstract
Description
Ziel der ErfindungObject of the invention
Das Ziel der Erfindung ist die Schaffung einer verbesserten Methode zur Aufklärung von biologischen und auch nichtbiologischen Strukturen mit Auflösungen von ca. 0,1-100 nm, wo herkömmliche optische Mikroskopie kaum anwendbar ist. Insbesondere ist die Methode vorgesehen für das Sequenzieren großer Proteine in der Proteomikforschung und zur Strukturaufklärung von Bakterien, Viren, menschlichen, tierischen und pflanzlichen Zellen.The The aim of the invention is to provide an improved method to the enlightenment of biological and non-biological structures with resolutions of about 0.1-100 nm, where conventional optical microscopy is hardly applicable. In particular, the method reserved for sequencing big Proteins in proteomics research and structure elucidation of Bacteria, viruses, human, animal and plant cells.

Beschreibung der ErfindungDescription of the invention
Erfindungsgemäß ist eine
Spitze für
spitzenverstärkte
Ramanmikroskopie so konstruiert, daß sie (a) eine Antenne für die Aufnahme
von Lichtenergie enthält,
welche eine erheblich bessere Energieaufnahme als ein einfaches
Nanopartikel am Ende eines Glasfaserkabels aufweist, wobei (b) die
Antenne eine nicht- oder wenigresonante Übertragungsspitze mit einem
Radius von unter 10 nm enthält,
auf die ein erheblicher Teil der Antennenenergie übertragen
wird und welche die Energie weiter zu den zu untersuchenden Molekülen leitet.
Da die Herstellung einer solchen Antenne mittels herkömmlicher
Verfahren, wie z.B. Elektronenstrahl- oder Röntgenlithographie sehr teuer
ist, erfolgt die Herstellung mit einem einfachen mechanischen Verfahren
(siehe Ausführungsbeispiel
1 und
Diese Einschränkung kann jedoch partiell überwunden werden durch Scannen in mehreren Orientierungen der Probe auf einem Drehtisch.These restriction but can be partially overcome by scanning in multiple orientations of the sample on one Turntable.
