In this brief review we illustrated on selected examples how combinatorial computational chemistry based on first principles quantum theory has made tremendous impact on the development of a variety of new materials including catalysts, semiconductors, ceramics, polymers, functional materials, etc. Since the advent of modem computing resources, first principles calculations were employed to clarify the properties of homogeneous catalysts, bulk solids and surfaces, molecular, cluster or periodic models of active sites. Via dynamic mutual interplay between theory and advanced applications both areas profit and develop towards industrial innovations. Thus combinatorial chemistry and modem technology are inevitably intercoimected in the new era opened by entering 21 century and new millennium. 

In the near future probably computer modelling, allowing the analysis of adsorption and elementary reactions at surfaces, will become increasingly helpful in catalyst selection. On the experimental side the field is changing drastically. Parallel testing equipment is now the state of the art. This field is often referred to as Combinatorial Chemistry . It is expected to have a large impact already in the near future. In fact, at present already companies have been formed in this field.

The Jaccard similarity coefficient is then computed with eq. (30.13), where m is now the number of attributes for which one of the two objects has a value of 1. This similarity measure is sometimes called the Tanimoto similarity. The Tanimoto similarity has been used in combinatorial chemistry to describe the similarity of compounds, e.g. based on the functional groups they have in common [9]. Unfortunately, the names of similarity coefficients are not standard, so that it can happen that the same name is given to different similarity measures or more than one name is given to a certain similarity measure. This is the case for the Tanimoto coefficient (see further).

Although, MediChem is a biosecurity products manufacturer, its biotechnology-based R D capabilities are worth mentioning here. The attended markets include Medical, Laboratory, Veterinary, and Environmental sectors. Medicinal chemistry services and drug discovery form the basis of the company, though their capabilities might be applied in a broader range of sectors. These capabilities comprise the areas of Proteomics, Combinatorial and Computational Chemistry, Medicinal Chemistry, Enzymes, Process Development, Analytical and Separations Chemistry, Chemical Synthesis and Scale Up.
