Description

Technical Field

[0001] The invention relates to the fields of biomedicine, biotechnology and laboratory technology, and in particular to a novel mixing device for suspended substances. Background Art

[0002] At present, microspheres are widely used in many fields such as biomedicine, chemical analysis, and environmental monitoring as important scientific research tools and industrial raw materials. Microspheres usually refer to particles with diameters ranging from nanometers to millimeters. They can be divided into polymer microspheres, silica microspheres, metal oxide microspheres, etc. according to their materials. Microspheres are also called resin products because of their unique physical and chemical properties. They have important applications in in vitro diagnostics (IVD), drug delivery systems, cell separation, and chemical synthesis catalysts.

[0003] However, microsphere sedimentation is a problem that may be encountered when using microspheres in liquid media, especially during long periods of operation or static conditions. This phenomenon can have a variety of effects on experimental results, such as:

[0004] Concentration variation: If your experiment relies on a uniformly distributed concentration of microspheres, sedimentation can cause differences in microsphere concentration at different locations or time points, affecting the consistency of your experimental results.

[0005] Standard curve distortion: In experiments that require the establishment of a standard curve (such as quantitative analysis using fluorescent microspheres), if the microspheres settle, the slope and intercept of the standard curve may change, thereby affecting the accuracy of the results.

[0006] Analysis and detection data bias: For experiments that require precise measurement of microsphere number or distribution (such as flow cytometry), microsphere sedimentation can lead to data bias because the distribution of microspheres after sedimentation no longer represents the state of the original sample.

[0007] Signal intensity fluctuations: If the microspheres are fluorescently or otherwise labeled, sedimentation may result in changes in the detection signal, thus affecting the final analytical results.

[0008] Cell capture efficiency: In cell capture or separation experiments, if the microspheres used settle, the cell capture efficiency may decrease, affecting subsequent cell processing and analysis.

[0009] At present, in order to reduce or avoid the impact of microsphere sedimentation on the experiment, the following measures can be taken:

[0010] Stirring or shaking: Keep the microspheres suspended by continuous stirring or shaking. Replace the microspheres: Use microspheres with a density close to the experimental medium, or choose microspheres with stabilizers to slow down the sedimentation rate. Short-time operation: Try to shorten the experimental operation time to reduce the possibility of sedimentation. However, these effects are limited and still cannot guarantee the mixing effect of the microspheres well, or they are difficult to implement. Summary of the invention

[0011] In order to solve one or some technical problems existing in the prior art, the purpose of the present application is to provide a new type of mixing device for suspended substances, so as to avoid the problem of uneven sample addition caused by the sedimentation of suspended substances in liquid and improve the mixing effect.
