Posted by Shannonms on April 17th Delanie Walker Jersey , 2017


With continuous development in technology, it has become easier for scientists and doctors to discover new ways of treating various ailments as well as explore more about the earth and its surrounding space. Nanotechnology deals in very small particles or structures that can be less than 100 nanometer in diameter where 1 nanometer is 1 billionth of a meter. So, it gives an idea about how much small particles are used by the scientists to conduct various researches. Nanotechnology creates a special interest because in their smaller size, materials reveal many unique properties that could not be seen in their original shape. And, their molecular structures also exhibit different properties when looked in smaller sizes.

In order to carry out the scientific researches Marcus Mariota Jersey , different kinds of fluorescent nanoparticles are utilized. Of late Fluorescent carbon nanoparticles have started to be widely used in various research programs due to their low-cost and good bio-compatibility. They have sizes of around 2-6 nanometer with quantum yields of about ~3%. CNPs are nano-crystalline and have predominantly graphite-based structure that come in green, yellow and red fluorescence under ultraviolet lights. Fluorescent carbon nanoparticles find their prominent use in cell imaging applications. They enter into a cell without causing any further functionality and the fluorescence property of these particles is used for fluorescence based cell imaging applications. The fluorescent detection of metal ions is another important application of these particles.

Most of us know about gold as one of the precious metals used in jewelry or for investment purposes. However, scientists have discovered that gold can also be used for conducting researches as well. Gold nanoparticles also known as nanogold have extraordinary optical, electronic and molecular-recognition properties. These properties make gold nanoparticles feasible for applications in various fields, like nanotechnology Wholesale Titans Hats , electron microscopy, electronics and materials science. Fluorescent gold nanoparticles can be conjugated with amine, biotin, carboxyl, methyl Wholesale Titans Hoodies , maleimide, neutravidin, streptavidin to be used in brightfield, darkfield, fluorescence and other imaging applications. They can also be conjugated with antibodies for drug delivery and sensing applications. And Wholesale Titans Shirts , they can be employed for gene therapy and gene specific sequence sensing as well.

If you need different kinds of nanoparticles for different applications, you can buy them from various manufacturers. Many companies having their own manufacturing facilities are providing the best nanoparticles in specific shape uniformity and reactivity. You can explore the internet and find these companies to know more about through their websites.

NAIROBI, Sept. 13 (Xinhua) -- Kenyan farmers could soon start growing Genetically Modified (GM) maize if an application by scientists for approval by regulatory agencies succeeds.


The country's leading scientists have written to the National Biosafety Authority (NBA) seeking permission to release the first ever Genetically Modified (GM) maize variety.


Gospel Omanya, Senior Manager of Deployment at the African Agricultural Technology Foundation (AATF), told Xinhua on Tuesday that most Kenyan farmers were ready for the GM maize which is pest and disease resistant.


"The farmers we interact with in Kenya and other countries where AATF operates are eagerly waiting for the genetically modified maize seeds to help them against impacts of climate change Wholesale Titans Jerseys , particularly drought and protection from insect pests such as stem borers and fall army worms," said Omanya.


He said the GM maize will boost efforts to achieve food security and better incomes from small holder farmers in Kenya.


Two months ago, Kenya grappled with Fall Army Worm (FAW) invasion which reportedly affected over 400,000 ha of maize across the East African region.


In areas where FAW infestation was reported for instance, the Tela variety which is genetically modified has been observed to have less damage in Kenya and South Africa.


The combined traits Cheap Titans Hats , including its drought tolerance, have resulted in maize grain yields of more than 30 percent over the best commercial hybrids, Omanya told Xinhua.


But even as the scientists await feedback from the country's biosafety authority, consumers still remain apprehensive over health concerns raised on genetically modified food.


"As it is, we have to be open minded as food prices continue to rise by the day Cheap Titans Hoodies , but on my part I'm still not sure if the GM maize is the solution. May be the concerned authorities should do more sensitization and let us know the pros and cons of having this maize grown in Kenya," said Jacob Ngetich, a small scale farmer.


He is among smallholder farmers in Kenya's Rift Valley region whose farms were affected by the FAW and his biggest worry now is to protect his farm against such an invasion in the future.


"Farming is my only source of livelihood, so I will do all it takes to protect it. I know there have been debates over GM maize in the country in the past, but as a farmer who has had firsthand experience with crop loss Cheap Titans Shirts , I would never rule out growing GM maize. I was not even aware of the application for seed approval but let us see what happens, all that matters is health safety of the consumer and of course food security," said Ngetich.


According to Omanya, before such maize is released to the consumer, proper due diligence has to be done to ensure it is fit for human consumption and Kenya is not an exception.
