Bioorganic chemistry of nucleic acids

A little guide for advanced search:

Tip 1. You can use quotes "" to search for an exact expression.
Example: "cell division"
Tip 2. You can use + symbol to restrict results containing all words.
Example: +cell +stem
Tip 3. You can use + and - symbols to force inclusion or exclusion of specific words.
Example: +cell -stem

e.g. searching for members in projects tagged cancer

About

The research interests of the laboratory for Bioorganic Chemistry of Nucleic acids reside in the synthesis of activated building blocks of chemically modified nucleoside analogs for their use in selection experiments for the crafting of functional nucleic acids with enhanced activities. Particularly, we strive to generate modified aptamers to be used as tools for medical imaging applications and the detection of specific targets such as enzymes, peptides, cancer cells, and small molecules. In addition, we are developing catalytic nucleic acids for the detection of DNA lesions as well as for their use as synthetic tools in molecular biology.

Expansion of the genetic alphabet with metal base pairs

Marcel Hollenstein (PI)

Expanding the genetic code beyond the A-T/G-C Watson-Crick canonical base pairs and 20 amino acids of natural organisms is a long standing goal in synthetic biology. Reprogrammation of the genetic code can lead to […]

Therapeutic tools based on nucleic acids

Marcel Hollenstein (PI)

An important research axis of the laboratory is to modify nucleic acids with chemical groups in order to improve their therapeutic usefulness. Particularly, modified aptamers (i.e. oligonucleotides capable of binding to targets with high […]

Synthesis of chemically modified nucleoside triphosphates

Marcel Hollenstein (PI)

Functional nucleic acids (aptamers, DNAzymes, ribozymes, and aptazymes) are generated by in vitro Darwinian evolution methods (SELEX and related methods of in vitro selection). We are interested to expand the capacity of these functional […]
