If you don't know the true face of Lushan Mountain, why don't you try ZEM15?

Hello, everyone, the popular science program of electronic microscope "ZEM15 Show You the World", which focuses on the things around you, is meeting you again. This issue uses ZEM15 desktop scanning electron microscope to show you the standing medicine around.

This article is only for popular science and has no guiding significance for drug selection.

One day, a friend of Xiaobian with a big brain asked Xiaobian a question: If I am sick and need to take cephalosporins, but the outer box of the medicine at home is lost, so I can't tell who is the cephalosporin.

Xiaobian: Go to the hospital to register, cephalosporins can't be eaten casually.

Friend: My father is a doctor. He said he could eat it.

Xiaobian: Go to the pharmacy to buy.

Friend: sold out.

small make up: usually drugs in addition to the outer box, soft packaging above also have a brief description.

Friend: I can't read the words on the soft bag clearly.

Editor: That...

Friend:...

Xiaobian: Then you can only try ZEM15 desktop scanning electron microscope!

In order to fill in the brains of friends and satisfy the curiosity of all the readers, Xiao Bian turned out all kinds of regular drugs in the family: cefdinir, amoxicillin, oral salt supplement, loratadine, Su Huang and other drugs.

words not much to say, directly on the ZEM15 desktop scanning electron microscope photos.

at first glance, there are mainly two types of particles in cephalosporin powder, one type of surface texture is single and relatively smooth, and the other type is a special-shaped body composed of more fine structures. A small partner who studied medicine told Xiaobian that cephalosporins are mainly composed of cephalosporins and diluents. Cephalosporins are the active ingredients of cephalosporins. According to the different preparation processes, cephalosporins will show several micron-scale small particles, and these small particles will agglomerate into irregular structures of tens to hundreds of microns, corresponding to the electron microscope photos. The structure-rich heteromorphs. The main components of the diluent are lactose, starch, etc. The function is to reduce the dose deviation of the main components and make the drug easy to form. The diluent is usually a block structure of tens of microns, which corresponds to a relatively smooth, single-textured block in the electron microscope photo.

Small cephalosporin particles of several microns can be seen more intuitively agglomerated into special-shaped large particles at high magnification.

diluent forms a massive structure with some cephalosporins attached to the surface.

let's look at amoxicillin, which is also a common antibiotic. Similar to cephalosporins, amoxicillin also has many diluents, and the structure is similar to cephalosporin diluents. The main component of amoxicillin is also a few microns of small particles, but these small particles do not seem to love reunion, mostly dispersed on the surface of the diluent.

Figure 9 Oral salt supplement (desktop scanning electron microscope 2000 times)

Oral salt supplement is mainly used to supplement diarrhea symptoms of dehydration, ingredients are various sodium and potassium salts. Under the electron microscope, it can be seen that the more regular small rectangular crystals agglomerate into large rectangular crystals.

Loratadine is often used for allergic symptoms. Under electron microscope, it can be seen that the main components are some powder particles of about 20 microns, and some of them will agglomerate into large particles of hundreds of microns. The above research of

is completed by ZEM15 desktop scanning electron microscope independently developed by Zeyou Technology. The electronic optical system, detector, circuit control system, signal acquisition system and operating software of

ZEM15 are all independently developed by Zeyou Technology. Specially developed electronic optical system design, so that the picture has a higher signal-to-noise ratio and contrast. With high-speed signal acquisition bandwidth, samples can be displayed smoothly at high quality video frame rate. All operations can be done with just a mouse, without the need for a diaphragm to medium complex steps. Host integrated high voltage and control system, easy to move, installation without special environment.
