What is forensic palynology used for?
Forensic palynology has been a law enforcement tool for over 50 years. Forensic palynology is the application of pollen and spores in solving legal issues, either civil or criminal. Pollen and spores can be obtained from an extremely wide range of items, including bodies.
How can palynology help forensic investigation?
Arguably the most important attribute for forensic evidence is that they have complex morphologies that can lead palynologists back to the parent plant they came from and allow them to create a unique picture of the location a crime may have occurred.
What is the main tool used in the field of forensic palynology?
Microscopes. Most palynology labs use light microscopes and/or electron microscopes to gather details about pollen and spores.
What is forensic nanotechnology?
Forensic Nanotechnology Nano-forensics, is a new area of forensic science which is highly advanced associated with the development of nano-sensors for crime investigations and inspection of terrorist activity by determining the presence of explosive gases, biological agents and residues [22-26].
How is palynology used in plants?
Palynology is a subdivision of plant science and geology that deals with pollen and spores. Pollen grains carry the sperm involved in sexual reproduction of vascular plants. Spores are cells that are involved with nonsexual reproduction in fungi and plants.
What is palynology and what can it tell us about the past?
Palynology can be used to reconstruct past vegetation (land plants) and marine and Freshwater phytoplankton communities, and so infer past environmental (palaeoenvironmental) and palaeoclimatic conditions in an area thousands or millions of years ago, a fundamental part of research into climate change.
Why is pollen used as evidence?
Pollen and spores are ideal forensic trace materials because the grains are small, highly variable, and found on almost any item that has been exposed to or comes in contact with the air (Milne et al. 2005). Transfers can occur between people, plants, and objects or a combination of contact between these things.
How did Nanotechnology impact the investigation?
The nano-based technology is immensely useful for the identification of the trace amount of fragmented explosives from the crime scene. This technology also helps the investigators to detect microscopic particles of gun powders on the shooter’s hand.
What is the role of palynology in taxonomy?
Palynology is the study of Pollen grains. Fossil spores are found in peat and other sediments, in lignite, coal and shales. They are evident since Pre-Cambrian times hundreds of millions of years ago. Pollen grains morphology plays an important role in taxonomic classification.
What is palynology and its scope?
Palynology is a branch of science concerned with the study of spore and pollen study whether living or fossil. The term palynology was first of all introduced by Hyde & Williams in 1944.
Who introduced palynology?
Hyde and Williams
The term palynology was introduced by Hyde and Williams in 1944, following correspondence with the Swedish geologist Ernst Antevs, in the pages of the Pollen Analysis Circular (one of the first journals devoted to pollen analysis, produced by Paul Sears in North America).
What are the energy applications of nanotechnology?
The energy applications of nanotechnology relates to using the small size of nanoparticles to store energy more efficiently. This promotes the use of renewable energy through green nanotechnology by generating, storing, and using energy without emitting harmful greenhouse gases such as carbon dioxide.
What is nanotechnology and nanomaterials?
Nanotechnology and nanomaterials can be applied in all kinds of industrial sectors. They are usually found in these areas: Carbon nanotubes are close to replacing silicon as a material for making smaller, faster and more efficient microchips and devices, as well as lighter, more conductive and stronger quantum nanowires.
What are the application areas of nanotechnology in agriculture?
The main application areas of nanotechnology techniques in the agriculture industry are Precision farming and Nano delivery systems The main application areas of nanotechnology techniques in the oil and gas industry are Sensors, Coating, Nanometers, Nanofluid and nanomaterials for drilling and completion, etc.
What are the diagnostic applications of nano biotechnology?
Diagnostic applications of Nano Biotechnology 1 Detection 2 Individual target probes 3 Protein chips 4 Sparse cell detection 5 Nanotechnology as a tool in imaging
