Designing the perfect sensor is the dream of any chemist. Since decades, a wide variety of synthetic receptors that targets analytes have been explored in chemistry. Their chemical optimisation is hard and does not guarantee success. In this context, we propose a fast and self-assembling colorimetric bio-chemical receptor coined Enzyvitand. It consists of only commercial chemicals and relies on the reunification of combinatorial chemistry, interactions of first and second coordination spheres interactions and indicators displacement assays that are harboured within a protein cavity. The sensor is highly modular, cheap and evolvable. Owing to it's solved X-ray structure and docking studies, we rationally designed it for the selective naked-eye recognition of dopamine over other neurotransmitters through the second coordination sphere. The supramolecular-anchored boronic acid into the protein allows also discrimination between (D)-Fructose versus dopamine relying on second coordination sphere. Hence, our sensor imitates a biological receptor for the recognition of neurotransmitters. Finally, it works in complex samples such as urine. Its immediate high versatility and evolvability are valuable for the selective detection of a wide assortment of analytes, ranging from small molecules up to micro-organisms. Regarding future applications, we anticipate new biotechnological or immunotherapeutic applications of our synthetic oligomer.
The literature is constellated with a wide variety of chemosensors against a plethora of analytes. This seminal library is used to inspire chemists to improve them using chemical synthesis. However, their optimization via chemical synthesis is a difficult task which takes time without the guarantee of final success.We show here that combinatorial chemistry,the use of first and second coordination spheres and the displacement of indicators united within a protein cavity offers an easy-to-assemble colorimetric bio-chemical sensor. It consists only of commercial chemicals. This colorimetric sensor is highly modular, cheap and evolvable. Its X-ray structure reveals the composition of its active site. This allows to design it rationally for the recognition of dopamine with the naked eye. Our bio-sensor therefore resembles a biological receptor for the recognition of neurotransmitters. Its immediate high adaptability and ability to be evolved can be useful for the selective detection of a wide variety of analytes going from small molecules to microorganisms. This discovery therefore makes it possible to dream of new biotechnological or new immunotherapeutic applications.<br>
