To me an extremely interesting article:

They succeeded in attaching gold tips onto nanorods by a simple
chemical reaction.

"Nanodumbells" gold-tipped nanocrystals which can be used as
highly-efficient building blocks for devices in the emerging
nanotechnology revolution have been developed by researchers at the
Hebrew University of Jerusalem.
The technology, developed by a research group headed by Prof. Uri
Banin of the Department of Physical Chemistry and the Center for
Nanoscience and Nanotechnology of the Hebrew University, is described
in an article in the current issue of Science magazine.
The nanodumbells shaped somewhat like mini-weightlifting bars
offer a solution to problems of building new, nanocrystal transistors,
the basic component of computer chips....
