Microbial Forensics And Its Applications in Investigations

Microbial forensics is a new and emerging discipline that first gained globally recognized as the result of the Bacillus anthrax attacks in 2001. This growing discipline still remains within the early stages of development and faces substantial scientific challenges to provide a sturdy suite of technologies for identifying the source of a biological threat agent and attributing a bio-threat act to a specific person or cluster. Microbial forensics refers to the investigation of the utilization of bio-weapon, and therefore the accidental unleash or natural development of dangerous microorganisms. It can be also defined as Microbial forensics as a scientific discipline dedicated to analyzing evidence from a bioterrorism act, bio-crime, or unintended micro-organism/toxin release for attribution purposes. The unlawful use of biological agents poses substantial dangers to individuals, public health, the environment, the economies of states or nations as well as global peace.

Touch DNA / Trace Biological Stain Visible Collection

Authors:  Song Zhihong, Zhou Xiuzhi DNA evidence is a powerful tool to help crime solve that each human’s DNA is entirely unique. The advanced and innovative DNA collection technique can improve working efficiency and solve cases in a forensic laboratory. Biological stains (bloodstain, semen stains, urine stains, hair roots, teeth, bone, tissue, etc.) and Touch DNA (shedding skin cells) are the main sources of DNA evidence that could be extracted. Touch DNA includes DNA from skin cells, which is transferred to objects when touched by hands or other body parts, and trace biological stain deposits in smaller amounts, both are invisible to naked eyes and too tiny amount to develop with traditional forensic lights. However, trace DNA evidence places a key role to determine the suspect in a criminal investigation. Common sources of DNA evidence that can be extracted at the scene of crime or forensic: Touch DNA: Shedding skin […]

Difference Between Prokaryotic and Eukaryotic Cells

The human body is an ecosystem that consists of multiple organs. Cells form the basic structural and functional unit of life. Not only does the cell store DNA but it also consists of multiple cellular components necessary for the working of a human body. Organisms can be broadly divided into two types based on the structure and components of their cells, mainly Prokaryotes and Eukaryotes. Key ingredients that make up a cell include plasma membrane, cytoplasm, nucleus (majorly the genetic material within), and ribosomes. Single-celled organisms that lack a nucleus and membrane-bound organelles are referred to as prokaryotes and the cell is referred to as prokaryotic cells. On the other hand, organisms consisting of cells that have a well-defined nucleus and membrane-bound organelles are referred to as eukaryotes and the cell is referred to as a eukaryotic cell. Prokaryotic Cells Generally, prokaryotic cells are not divided up inside through membrane […]
