Recently, "Forensic Pioneer III" has been a TVB TV series that has been sought after by everyone. The most influential ones are those criminal investigation dramas with high IQ duel and deep human fighting. Treacherous and tortuous cases, modern and sophisticated instruments, stunning detection techniques, and approaching the legal pioneer3, it is not difficult to find that high-tech and reasoning elements will account for a very high proportion. The description of the process of analysis, etc. is even more amazing.
Generally speaking, the analysis and testing of instruments usually appear in scientific research institutions and laboratories. Legal personnel are like researchers in laboratories. They use the most advanced detection instruments in the world today to examine the evidence left at the crime scene, and conduct methods such as investigation, comparison, comparison, analysis, and laboratory tests. Through the superb physical evidence inspection of high-tech instruments and layer-by-layer analysis, various inspection and analysis reports are obtained, which successfully help solve the case. Among them, the most widely used is the mysterious DNA test and fingerprint comparison test, I do not know whether the scientific analysis instruments in reality can achieve such high accuracy.
Magical instrument analysis and detection case
Evidence of shoes and clothing: The police found that a suspect had something sticking to the sole of the suspect, so he submitted the shoe to the forensic department for further inspection. The forensic director tested the black substance stuck on the sole of the shoe, which was originally asphalt The forensic director tested the stains on the clothes of one of the dead in the re-shooting case, and it was confirmed that the stains were the fish oil stains of bluefin tuna, linking the two seemingly unrelated cases.
Biopsy: A knife injury caused by a person before and shortly after death is different. Doing a tissue biopsy shows that the deep wound of the knife wound caused by a person's death is relatively mild.
DNA extraction: To take DNA without dental pulp, first freeze the teeth with liquid nitrogen to make the teeth fragile, and then put the fragments of the teeth into the solution to dissolve, so that the DNA will be dissolved in the liquid together.
The mystery of color-changing flowers: Hydrangea is a very interesting flower species. Its color pigments will change color due to the combination with the aluminum in the soil. The aluminum element will have different solubility because of the difference in pH of the soil, that is, the color of the flower will change color according to the soil with different pH. The PH value of the red medicine is 7 ~ 7.2, and the soil is alkaline. The PH value of purple flowers is 5-6, and the soil is more acidic. Put a few rusty iron needles, the flower will change from white to purple blue. With a few drops of soapy water, the soil becomes alkaline and the flower turns red.
Demystifying the principle behind high-tech instruments
Some netizens said: I have to say that the instruments in the forensic are too strong! What elements, ingredients, and substances must not be said, even the green tea marine essence in cosmetics, and the satay sauce made with Sichuan pepper , Paints containing special substances (even knowing the place of origin), volcanic ash of a certain composition unique to a volcano in a certain place ... all can be detected! Is it really god?
Take a closer look at the close-ups of those instruments, that is, ordinary ovens, rotary evaporators, elemental analyzers, etc., and some application software devices marked "match" and "notmatch". In fact, it is very troublesome to analyze a substance out of thin air. A detection method, whether it is nuclear magnetic, infrared, elemental analysis, electronic lens, etc., cannot be determined. At most, you have a target structure, which is then used to compare Yes, see if it meets.
All in all, many magical analytical experiments are to meet the needs of the plot, but the principle is still very consistent with the method of scientific research. We can be inspired by this, through the joint efforts of the entire industry, in the near future, we also look forward to the application of scientific and technological instruments with higher analysis efficiency and accuracy in the fields of food, medicine, and biology.
