PRLog - May 8, 2014 - RAJAPALAIYAM, India -- Indian researcher Ms.Theivasanthi has recently prepared “The World’s first plants materials based superparamagnetic particles” - named as “Santhi Particles”. It has been observed room temperature superparamagnetic behavior in that plants materials (Acalypha indica, Cynodon dactylon, Terminalia chebula, Eugenia jambolina and Cassia auriculata). These plants have been known for Diabetes treatment and have antioxidants. One of the plants Cynodon dactylon has anti-cancer properties also too.
Magnetic behaviors of Plants Materials
In this series, some more attempts have been made to invent superparamagnetic particles from vegetables and food materials. The details have been released in the data set: www.goo.gl/vwisgn . Particles of Curcuma longa and Cocos nucifera showsuperparamagnetic behavior (particle size 20 nm and 18 nm respectively – size calculated from VSM analysis).
Particles of Amorphophallus konjac (particle size 21 nm calculated from XRD analysis) and a mixed vegetable powder (Cyamopsis tetragonoloba, Vicia faba, Momordica charantia and Abelmoschus esculentus) not showsuperparamagnetic behavior. Both these powders have anti-diabetic and antioxidant properties. In addition, Konjac powder has anticancer properties and its nanosize may increase its cancer and other properties.
These research activities will lead to new concept in magnetic research in near future. VSM analyses of the samples have been done at SAIF, IIT Madras (India). Further research on this issue is undergoing. Superparamagnetic nanoparticles have many industrial applications and biomedical applications like Contrast agents in Magnetic Resonance Imaging (MRI), Magnetic separation, targeted drug delivery, hyperthermia of cancer etc.
Making these plants based powders as bio-nano powder using nanotechnology will improve their results. The concept involved in the bio-nano powder is, “reducing the medications means lesser the side effects”. Also, the nano-size will increase the specific surface area and site of actions of this powder. Nanoparticles usually have better or different qualities than the bulk material of the same element and have immense surface area relative to volume. As the size of a particle is reduced, the number of defects per particle is also reduced and mechanical properties rise proportionately
Special features: The plants / food based superparamagnetic particles have no / very least side effects as well as bio-compatible nature. Low cost / mass production within short time - Produced from the materials already in consumption by human & animals internally / externally.
The researcher calls all the interested collaborators / researchers to contact her for collaborative works.
