Chemical Reactions in Living Systems

Dominik Schauenburg,
Tanja Weil

Abstract: The term “in vivo (“in the living”) chemistry” refers to chemical reactions that take place in a complex living system such as cells, tissue, body liquids, or even in an entire organism. In contrast, reactions that occur generally outside living organisms in an artificial environment (e.g., in a test tube) are referred to as in vitro. Over the past decades, significant contributions have been made in this rapidly growing field of in vivo chemistry, but it is still not fully understood, which transformations pr… Show more

“…To achieve this, the design of novel active biomaterials as well as coupling of microprinted elements with living microorganims must be targeted. [236] Furthermore, special focus must be placed toward more precision and complexity in the response of the printed devices in a specific environment, ranging from physiological conditions necessary for biomedical applications to confined spaces as in the case of microfluidics or optics. Also, new approaches toward advanced multi-stimuli responsive materials as well as modular assembly strategies are very promising.…”

“…The covalent decoration of the extracellular vesicles surface with targeting ligand, namely, the peptide sequence PTHTRWA specific for the A549 cell line, was performed using the 1,3-dipolar cycloaddition reaction, that is, click chemistry reaction. The wide employment of click chemistry processes in designing the bioprobes results from conducting such reactions fast at mild conditions, as well as from their high selectivity and shows compatibility in aqueous media. The scheme of the bioconjugation process is presented in Figure .…”

“…Synthetic chemistry has enabled the rational design of biomaterials, able to influence cells on a larger scale. Although these two fields have evolved separately, there are several calls to merge progress, including a very recent report by DeForest and Anseth et al, toward the creation of living materials. , Here, one can envision the chemical design of a scalable hydrogel, which can be manipulated by a cell. Recent collaborative work by Kietz and Rosales lab shows this is possible. , Further innovations can leverage the synthetic material to create the environment and 3D shape, while the living cells provide the biological complexity and production of biological molecules.…”
