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>

<div><div><div><p>Designing the perfect sensor is the dream of any chemist. Since decades, a wide diversity of chemosensors targeting analytes has been explored in chemistry. Their chemical optimization is hard and with no guarantee of success. In this context, we propose a fast and easy-to-assemble colorimetric bio-chemical receptor coined Enzyvitand. It consists only of commercial chemicals. It relies on the reunification of combinatorial chemistry, first and second coordination spheres interactions and indicators displacement assays. All harbored within a protein cavity. The sensor is highly modular, cheap and evolvable. Thanks to its solved X-ray structure, we rationally designed it for the naked-eye recognition of dopamine. Hence, our sensor imitates a biological receptor for the recognition of neurotransmitters. Its immediate high versatility and evolvability is valuable for the selective detection of a wide assortment of analytes from small molecules up to micro-organisms. For the future, we anticipate new biotechnological or immunotherapeutic applications of our bio-sensor.</p></div></div></div>

A colorimetric sensor based on TADA–AuNPs accompanied by a masking agent DPC was constructed, with which the rapid quantification of Al3+ can be realized by UV-vis spectroscopy or naked eye observation.
