What are some of the applications of ferrofluids?
Ferrofluid is used in rotary seals in computer hard drives and other rotating shaft motors, and in loudspeakers to dampen vibrations. In medicine, ferrofluid is used as a contrast agent for magnetic resonance imaging (MRI).
What are the applications for PCR?
The polymerase chain reaction has been elaborated in many ways since its introduction and is now commonly used for a wide variety of applications including genotyping, cloning, mutation detection, sequencing, microarrays, forensics, and paternity testing. Typically, a PCR is a three-step reaction.
What are the applications of PCR Class 12?
PCR or Polymerase Chain Reaction is a technique used in molecular biology to create several copies of a certain DNA segment….Applications of PCR
- Testing of genetic disease mutations.
- Monitoring the gene in gene therapy.
- Detecting disease-causing genes in the parents.
Why are ferrofluids important?
A major benefit of ferrofluid is that the liquid can be forced to flow via the positioning and strength of the magnetic field and so the ferrofluid can be positioned very exactly. Ferrofluids also have the capability of reducing friction, making them useful in a variety of electronic and transportation applications.
Can ferrofluids be controlled by magnets?
Because ferrofluids are very easily magnetized (they have an incredibly high magnetic susceptibility), the peaks can be produced using a small bar magnet. Upon application of an external magnetic field, the nanoparticles align with the field.
How is PCR used in medicine?
The polymerase chain reaction (PCR) is used to make millions of copies of a target piece of DNA. In some cases, gene therapy is available to address these disorders, and PCR is used to monitor the functioning of the relevant genes and gene segments. …
What is PCR in medicine?
PCR (polymerase chain reaction) tests are a fast, highly accurate way to diagnose certain infectious diseases and genetic changes. The tests work by finding the DNA or RNA of a pathogen (disease-causing organism) or abnormal cells in a sample.
What is PCR write its various types and its application?
Polymerase Chain Reaction (PCR)- Principle, Procedure, Types, Applications and Animation. Polymerase Chain Reaction (PCR) is a powerful method for amplifying particular segments of DNA, distinct from cloning and propagation within the host cell. This procedure is carried out entirely biochemically, that is, in vitro.
What is the use of PCR in molecular biology?
PCR, or the polymerase chain reaction, is a chemical reaction that molecular biologists use to amplify pieces of DNA. This reaction allows a single or a few copies of DNA to be replicated into millions or billions of copies.
Who invented ferrofluids?
Steve Papell
The first ferrofluid was invented by a NASA engineer named Steve Papell in the early 1960s. His idea was that if you add these magnetic nanoparticles to fuel, you can move it around in zero gravity with a magnetic field. That didn’t really pan out. But since then, ferrofluids have been used far and wide.
Are ferrofluids toxic?
The toxicity of ferrofluid is very low; animal experiments in which the permissible maximum doses of ferrofluid were either administered orally, intravenously, or intraperitoneally did not kill the mice.
How does a Ferrofluidic seal work?
A Ferrofluidic® seal takes advantage of the response of a magnetic fluid to an applied magnetic field. When fluid is applied to this gap it assumes the shape of a liquid O-ring and produces a hermetic seal.
What can ferferrotec’s EMG series ferrofluids be used for?
Ferrotec’s EMG series ferrofluids can be used to improve performance in applications that include inclinometers, accelerometers and flow meters, tilt, vibration, pressure and level sensors, and various switches.
Why are ferrofluids easy to handle?
Ferrofluids are easy to handle because the fluid location can be controlled through the use of a magnetic field. They can be forced to flow by varying the strength of the magnetic field. Ferrofluids are prepared by suspending tiny particles (10 nm diameter) of magnetic solids in a liquid medium.
What are ferferrofluid seals used for?
Ferrofluid seals are also used to remove dust particles in high-speed computer disk drives. They prevent dust and other impurities from the drives hence protecting the data-reading heads from crashing into the disks. 3. Loudspeakers
Can ferrofluid be used to cure retinal detachment?
Ferrofluid could be verified by medical researches to be used to cure retinal detachment by sealing tiny retinal holes. Retinal detachment is the leading cause of blindness, 13. In optics, researchers are confident they will be able to create high-quality reflective surfaces inside telescopes by suspending Ferrofluid in ethylene glycol.
