How to Controll Drugs and Narcotics by Safity, Non-destructive Identification?
It is a non-contact and non-destructive and does not require any sample preparation for raman spectrometer. However, further investigations of the same specimen to confirm results can preserve small traces of evidence.Additionally, the the high spatial tesolution of confocal system enables performing a complete analusis withe small sample volume.In the field of Forensic Science, they make the technique as an efficient and robust analytical method.
The analyst often needs to analyze mixtures of drug particles and cutting agents. Manitol, myoinositol and sorbitol have been analyzed as possible cutting agents and their Raman spectrometer are depicted in Figure 3. The results clearly show that the spectra of cutting agents differ from each other as well as from the reported spectra of drugs.

How to Detect Hydrogen Peroxide of Cells by Raman Spectroscopy
Hydrogen peroxide(H202)is a
key part of reactive oxygen species(ROS)and generated
as a
by·product of a wide range of biological processes. It has a diverse array of physiological and pathological effects within living cells depending on the extent, timing, and location. Such as stimulating cell proliferation, intracellular signal transduction, Excess hydrogen peroxide can lead to structural and functional derangements of cell lipids, proteins, DNA and other molecular. Because of its easy access and relative stability,it has become an important tool for cellular oxidative damage research. The mechanisms of cellular damage induced by Hydrogen peroxide are concern of research．

How to detect heparin by handheld Raman spectroscopy?
Good news! Handheld spectrometer, which is poducted by Optosky, successfully detected heparin. On October 29, 2019, Brazil tested the heparin signal using Optosky's portable spectrometer. Prior to this, heparin could not be tested using the Truscan and NanoRam instruments. This is a huge success for Optosky's handheld spectrometer.

Where is the handheld Raman spectrometer applied?
Handheld Raman analyzer system can be applied to many aspects such as material identification, biochemical analysis, food and drug testing, environmental monitoring, dangerous goods testing, and jewelry analysis and analysis.
The Raman probe is a phenomenon in which when a strong monochromatic light illuminates a transparent substance, the frequency is changed by scattering by the substance molecules, and the frequency is determined by the characteristics of the scattering substance. Raman spectroscopy is the result of the superposition of the vibrational energy or rotational energy of a molecule and the photon energy when an incident photon collides with a molecule. Raman spectroscopy can be used to transfer the molecular energy spectrum in the infrared region to the visible region for observation. Therefore, Raman spectroscopy, as a supplement to infrared spectroscopy, is a powerful weapon for studying molecular structure.
In recent years, the rapid development of laser measure has brought about a great change in Raman spectroscopy. The modular spectrometer is moving from large Raman spectroscopy to portable Raman spectroscopy, from large laboratories to civilian and commercial.
The following are several application examples for Raman spectrometers:
