The field of molecular sensing is immense. It is nearly the whole world of natural
and synthetic compounds that have to be analyzed in a variety of conditions and for
a variety of purposes. In the human body, we need to detect and quantify virtually
all the genes (genomics) and the products of these genes (proteomics). In our surrounding
there is a need to analyze a huge number of compounds including millions
of newly synthesized products. Among them, we have to select potentially useful
compounds (e.g., drugs) and discriminate those that are inefficient and harmful. No
less important is to control agricultural production and food processing. There is
also a practical necessity to provide control in industrial product technologies,
especially in those that produce pollution. Permanent monitoring is needed to maintain
the safety of our environment. Protection from harmful microbes, clinical
diagnostics and control of patient treatment are the key issues of modern medicine.
New problems and challenges may appear with the advancement of human society
in the XXI century. We have to be ready to meet them.
