Question

Atomic force microscopy can be used for ___________.

1) the monitoring and determination of molecular structure
2) nanomanipulation to pull or push on a specimen in an attempt to measure
various mechanical properties
3) determination of the affinity of a receptor for its ligand
4) changing one element to another by forcing protons out of an atomic nucleus
A) 1
B) 2
C) 3
D) 4
E) 1, 2 and 3

Answer 1

Atomic force microscopy can be used for monitoring and determining molecular structure, as well as nanomanipulation to measure mechanical properties. It is not used for determining receptor affinity or changing elements through nuclear reactions.

Step-by-step explanation:

Atomic force microscopy can be used for 1) the monitoring and determination of molecular structure. AFM can provide detailed information about the surface structure of specimens at the atomic level by measuring variations in the height of the probe tip as it passes over the specimen.

It can also be used for 2) nanomanipulation to measure various mechanical properties. AFM can apply forces to the specimen and measure the resulting deflection, allowing researchers to study the mechanical properties of materials on a nanoscale.

However, AFM is not used for 3) determination of the affinity of a receptor for its ligand or 4) changing one element to another by forcing protons out of an atomic nucleus.
