Electron Microscope Forensic Science Tools Have Made Things Easier
With the passing time, the electron microscopes are being used as an effective tool in many different areas. Earlier, the electron microscopes were considered as a sophisticated tool and were used only by the scientists in their research work. But now, the electron microscopes have expanded their area of work and are used as an efficient tool in forensic science. It may well be noted that forensics is a science of the related scientific tests or techniques used in the investigation of crimes. We will now be seeing the impression of electron microscope forensic science tools
The Scanning Electron Microscope (SEM) is providing more and more certain answers to the criminal related troubles since its commercial launch way back in 1965. And, it must be said that by using electron microscopes forensic science has gained a lot. The true uses of these indications are decided by the preparation of the sample and instrumental parameters. The main use of forensic science is for the purposes of judicial enforcements, to investigate in the criminal cases such as fraud, theft, robbery, murder and alike. The forensic science needs the services of electron microscopy in various cases like biological samples, study of paints, fibers, hair, gunshot remains, or any other chemical found from the crime site. The image analysis is very much necessary for the translation of the physical proof.
Experts often develop photographs to see minute particulars which are urgently required in the forensic study. Image analysis is also used to identify the main details from the CCTV cameras. Now, you must be starting to realize that in forensic electron microscopy plays a major role.
Sometimes, when the gunshot-residue (GSR) is not found on the gunner's hands, then it is possible that it may be found on his clothes or in his hair. To come to this conclusion, a Scanning Electron Microscope (SEM) can be used to locate these tiny GSR particles. The very high temperatures of a blast can melt and distort these GSR particles. The SEM can distinguish these by-products of a bullet's burning. Also, the SEM is used in addition with Energy Dispersive X-ray (EDX) to decide a chemical fingerprint of the object being examined upon. The presence of lead, antimony, and barium in these minute particles while using the SEM/EDX technique suggests that the substance is GSR. But, the SEM/EDX is not suitable for the analysis of very small particles. The SEM lacks the 3-D segmenting capabilities of scanning beam confocal microscopes, which it overcomes by its imaging capabilities. The electron microscope is, therefore, a major tool in forensic research and investigation and with the advent of electron microscope forensic science tools would never have been better.
