3. Abstract
 In recent years , the world of science has started to produce advanced
materials and technology in the nano scale, which known as
nanotechnology . The use of nanotechnology has become wide spread
in all branches of science , so there is an essential need to prepare
advanced nanotechnology tools and detection systems contain very
recent instruments needed for nanotechnology studies , since the
physical , chemical and biological properties of the material at nano
scale differ in fundamental and valuable ways from that at normal
scale. In this work the different technique in measuring and detection
techniques in nanotechnology will be discussed the method of
operation and accuracy of each technique will be evaluated, the main
applications of each technique in industrial and construction field will
be evaluated. The techniques mentioned are Nano indentation
technique which evaluate the mechanical properties of the nano-
materials such as reduced modulus, stiffness and Hardness. The
quantitative and qualitative analysis detection systems such as SEM ,
AFM, STM and Zeta potential will be evaluated . The analysis and
tooling equipments will be also evaluated. At the end of work the main
conclusions and recommendation about using nanotechnology
detection tools and difference between them are mentioned.

18. Scanning Tunneling
Microscope STM
The principle of the STM. The instrument relies on the
tunneling current between the conducting substrate and
the metallic scanning tip. Through a computer controlled
feed-back loop and a piezo-element this current controls
the height d over the substrate. Scanning across the
surface is controlled by a piezo-robot. The feed-back
voltage is used as output. To the right is shown a 3 nm by
3 nm surface scan with atomic resolution of a graphite
surface,
