Problems solved by technology

However, this quartz can only oscillate at one frequency when a current is applied to its terminals
Current in the electrode terminals can be transferred to the quartz terminals in an undesired manner, such as conduction through salt crystals in the liquid, which can cause false detections of terpenes
Furthermore, the device only allows a single measurement to indicate the presence or absence of terpenes and cannot quantify the terpenes present

Embodiment Construction

[0038] Continuing with the description of the device for detecting an analyte in a liquid according to the invention, like reference numerals denote like parts. According to the invention, in particular, the device is intended to detect fungicides such as iprodione in wine; however, it is obvious that the device according to the invention can have many applications, such as Detection of fungicides in water. For example, as part of the present invention, the analytes that can be detected belong to the family of microorganisms such as viruses, bacteria, molds or belong to the family of biologically active organic molecules such as pesticides, toxins, endocrine disruptors, hormones, enzymes, vitamins, antibiotics and drugs or ionic families such as major minerals, toxic metals, organic acids or organic bases; or biomolecular families such as lipids and their derivatives, amino acids and their derivatives, peptides and their derivatives, proteins and their derivatives, unbranched ...

Abstract

The invention discloses a sensor and device for detecting an analyte in a liquid. The invention relates to a sensor (1) for detecting an analyte in a liquid. The sensor consists of an antenna (13), covered with a layer of a molecularly imprinted polymer (12) capable of interacting with an analyte and inducing a variation in the characteristics of the antenna (13) within the microwave frequency range.

Description

technical field [0001] The present invention relates to a microwave transduction sensor consisting of "molecularly imprinted polymers" (MIPs) as sensitive materials, and more specifically, silicon-based molecularly imprinted materials called "molecularly imprinted polymers" Silicon" or MIS. The invention also relates to a device for detecting an analyte in a liquid. The invention is particularly advantageous when used for the detection of fungicides such as iprodione in hydroalcoholic media. Background technique [0002] In particular, in the field of analytical chemistry, it is known to have various devices for analyzing liquids such as water or wine, for example, in particular, to determine the chemical content of said liquid, and more in particular, to determine the presence or absence of contaminants such as fungicides. [0003] Of these, test strips or chromatography are the most commonly used systems. [0004] Test strips do not allow detection of traces of fungici...
