A mobile gantry microarray sensor preparation device

Abstract

The invention discloses a movable gantry type micro array sensor preparing device. The device comprises a base, a gantry, an X-axis control mechanism, a Y-axis control mechanism, a Z-axis control mechanism and a sample application head, wherein guide rails I are arranged on the two sides of the base respectively, the gantry comprises a chassis, a left stand column, a right stand column and a cross beam, the chassis is arranged in the base, the guide rails I are sleeved with the two ends of the chassis, and the cross beam is horizontally arranged on top of the left stand column and the right stand column; the X-axis control mechanism comprises a motor I, a mechanical slide table and a lead screw I, the Y-axis control mechanism comprises a motor II and a lead screw II, and the Z-axis control mechanism comprises a motor III, a lead screw III, a guide rail II, a lead screw nut and a slide plate; the sample application head is arranged on the outer side face of the bottom of the slide plate. Through structural design of the sample application device and X-axis, Y-axis and Z-axis travel control, large-scale preparation of array sensors is achieved; by means of numerical control equipment and the stability of the gantry structure, high positioning accuracy of the sample application device and size uniformity of the array sensors are guaranteed.

Description

technical field [0001] The invention relates to an array sensor preparation device, in particular to a mobile gantry type microarray sensor preparation device for large-scale preparation in a temperature-controllable environment filled with protective gas. Background technique [0002] The bionic sensor array system is also called the artificial smell and taste system. It simulates the human smell and taste system, and uses the cross-response between the array sensor composed of multiple chemical substances or biomacromolecules and the target analyte to realize the detection of various The detection and identification of substances, the system shows high selectivity and high specificity for trace target analytes, especially the microarray system based on bioenzyme sensors also has good biocompatibility and rapid degradation Therefore, it can be predicted that this kind of bionic sensor array system based on chemistry or biology will be widely used in food safety detection, b...

AI Technical Summary

Problems solved by technology

[0004] 1. Array sensors are disposable sensors, so it is often necessary to prepare a large number of array sensors in medical testing, biological or chemical experiments

[0005] 2. Different types of sensors and sensor arrays or sample sizes are different. Currently, array chemical sensor preparation devices or biochip spotters on the market can only prepare sensors for a single object, so various array sensor preparation devices have not been available. full and effective use

[0006] 3. Sensor array points are easily affected by the environment: for example, chemical sensors based on porphyrin molecules are easily polluted by the outside air, resulting in reduced sensitivity or failure of the sensor; biosensors based on genes or proteins are easily affected by the external environment such as Loss of activity due to interference with temperature, chemical substances in the air, etc.
