Problems solved by technology

In addition, because the measurement method in the prior art is carried out with a highly complex mechanical structure, its cost is relatively high, and because the parameters of the measurement method are related to the designed mechanical structure, it is necessary to apply various complex methods when calculating its quality. mechanical model of
However, biological or chemical detection is often a large number of detections and is carried out in a fluid environment. The above-mentioned existing technologies are not suitable for biological or chemical detection due to high cost, complex models for calculation and only in a vacuum environment.

Embodiment Construction

[0040] refer to Figure 1A as well as Figure 1B , Figure 1A shows a top view of an oscillator 1 according to a specific embodiment of the invention; Figure 1B show Figure 1A Side view of Oscillator 1. Such as Figure 1A as well as Figure 1B As shown, the oscillator 1 includes a linear protein structure 10 , a load 12 and an auxiliary 14 . The auxiliary material 14 is used to fix the two ends of the linear protein structure 10 on the base (not shown in the figure), and the load 12 is arranged on the linear protein structure 10 and between the fixed two ends. The distances are roughly equal. Please note that in practice, the oscillator can also be fixed on the base in other appropriate ways, and is not limited to the way of fixing with auxiliary objects in the specific embodiments listed in this specification.

[0041]In this particular embodiment, the thread-like protein structure 10 can be located on the surface of the microorganism 16, that is, the flagella of the mi...

Abstract

The invention discloses an oscillator which comprises a line protein structural body and a load. Two ends of the line protein structural body are respectively fixed on a base. The load is attached to the attaching position of the line protein structural body, wherein distances from the attaching position to the two ends of the line protein structural body are approximately equal. When the line protein structural body oscillates, the oscillation frequency is related with the mass of the load. Therefore, the mass of a small matter can be measured by the line protein structural body.

Description

technical field [0001] The present invention relates to an oscillator, a mass measuring system, and a mass measuring method, and in particular, the present invention relates to an oscillator, a mass measuring system, and a mass measuring method capable of measuring the mass of a minute object in a fluid environment. Background technique [0002] In recent years, due to the progress of micro-electro-mechanical, nano- and biotechnology, various micro-electro-mechanical materials, nano-materials, and biomaterials have been regarded as materials with a wide range of applications and have attracted attention from all walks of life. And because today's technology tends to be miniaturized, the research on new materials not only studies its macroscopic properties, but also its microscopic properties is also a key topic of research. From a microscopic point of view, the measurement of the basic properties of matter, such as the measurement of mass, electrical properties, or mechanica...
