Microfluidics Essays

Personal Statement Over a casual dinner-table conversation a few years ago with a chemical engineer, my curiosity about his profession led to quite an engaging discussion between us. I was amazed by the several innovations brought about by the Chemical Engineering fraternity which have changed the lives of so many people across the globe. For example, he told me the dramatic change in the gasoline production levels which came about due to the Houdry Process in 1934. It set me thinking on what a remarkable

Make-up, fragrances, cleaning supplies, medicine, body wash: these are all items that can be bought at almost any store in the United States. Many big companies test these products on animals to identify the quality and their effectiveness. Animals should not be used for experimentations because they are living being, just like us. Not only is this practice cruel and inhumane, it is not accurate for animals to be tested on because their bodies are so different from human bodies while there are alternative

inhibitor Mibefradil produced an inhibitory effect on bovine sperm hyperactivation. This effect occurred as a delayed induction of hyperactivation. Furthermore, it was found that Mibefradil produced an inhibitory effect on sperm progression through a microfluidic device in comparison to the caffeine controls. This finding in conjunction with the observed stimulatory effects of high extracellular pH, NH4Cl and caffeine indicates that

Johnny Depp stated, If you don’t like seeing pictures of violence towards animals being posted, you need to help stop the violence, not the pictures. Animals are good to have around because they are entertaining to watch and play with. Animals are also good for getting rid of the bad thing that come into our world like the bad bugs. Animals are even used to test products such as shampoo ,medicine, and perfume. So therefore, Animal testing should not occur because it is hurting the animals and making

Chromosomes are pulled apart during mitosis; this not a gentle process. To prevent this important genetic information from being lost from the ends of the chromosome, telomeres protect this important information from being lost by taking the loss of its own base pairs. During mitosis, when the telomeres lose some base pairs, they can remain shortened and lead to further breakdown of the telomere, or the enzyme telomerase can add new base pairs allowing new generations of daughter cells to follow

The use of catalysts by mankind, dates back thousands of years, in processes such as wine- or bread-making. Their reaction scope is enormous and thus, they play an important role not only in natural processes, but in commercial processes as well. The latter include among others, the commercial production of chemicals, medicines and foods. According to IUPAC, a catalyst is a substance that has the ability to increase the reaction rate, when added to a reaction, without itself getting consumed in

Humans use many tests to check the reliability and safety of products such as medications and cosmetics, and specific types of testing use inhumane methods to produce results. Finding new medical treatments is extremely important, but sometimes people abuse their rights and resort to unnecessary and dangerous tactics to find solutions. Animal testing is a practice of brutality that is forced upon millions of animals worldwide. Out of all the reasons to explain why this practice is wrong, the most

Next, microdosing, it can be used in human volunteers by donating the blood and then the blood will be analyzed. Besides that, artificial human skin, is made from sheets of human skin cells grown in test tubes and can produce more useful results. Microfluidic chips, which are lined with human cells and recreate the functions of human organs, are in advanced stages of development. Lastly, computer models, it can predict the toxicity of substances on human molecular structures without invasive experiments

These days, many companies use a variety of methods for product development and stability verification. One of them, animal experimentation, has been a controversial issue in the past until now and it has also confronted with various reactions in regards to its admissibility. We need to respect and cherish the dignity of animals. They are, like humans, are entitled to basic needs and their way of life should not be intervened and determined by human beings. Also, animal experiments are an act of

Undoubtedly, many people feel indebted to the thousands of scientists and researchers, whose groundbreaking discoveries have lead to various vaccinations and contributions. However, have you ever stopped to wonder how these results are attained? The answer: through testing on innocent, naive animals. Everyday, animals are abused for the purpose of scientific inquiry. Although technology plays such an eminent role in today's society, scientists refuse to use methods which are more humane. If testing

My undergraduate experience was a mixed bag. Independence was a wonderful change of pace but with that independence came the opportunity for poor decisions. Not the poor decisions that are generally affiliated with “going off to college” but rather, a more subtle variety. Most glaring amongst these was my decision to focus on course work to the exclusion of extracurricular activities, service, and teaching. The final year and a half of my undergraduate career forced me to reevaluate these decisions

Every year, around 100 million animals are killed due to animal testing. Research on animals has been around since at least 500 BC. Animals are tested on to help develop medical treatments, check the safety of products that will be used by humans, and for other types of research. During this research, these animals are tortured and killed. This has caused a lot of controversy throughout history. One side argues that it is cruel and inhumane and needs to be stopped, while the other side argues that

Since ancient times, animals have been experimented on by humans. The greeks used animals to advance anatomical study and further understanding of the body. Starting in the twelfth century, surgical procedures were tested and studied using animals. Because anesthetics were only greatly introduced in the mid- nineteenth century, the animals suffered through every cut and every poke (Scutti, Susan). Those who argue that animal experimentation is necessary claim that treatments for diseases like polio

is a sheet made of human skin cells that can produce more effective results than testing chemicals on animal skin. Computer models also can help predict the toxicity of substances without harming or experimenting on animals. Furthermore we have microfluidic chips and micro dosing, these techniques scrutinize a human living system and results in data that is relevant to humans ("Animal Testing

Over 100 million animals are used every year in the United States for cosmetic, and scientific testing. Animals are used to develop medical treatment, determine toxicity in medications, check the safety of products for human use, and other biomedical, commercial, and healthcare uses. Advocates of animal testing claim that it has implemented the development of numerous life-saving treatments for both humans and animals, also that there is no other alternative method for researching a complete living

Every year more than 100 million animals are killed due to animal testing. Animal testing is still acceptable almost all over the world. Sadly, many people still believe that it’s okay to murder animals to benefit the human race. Animal testing is cruel, unnecessary, and not worth it. Humans are wasting animals lives and it needs to stop. Animal testing is cruel and it's morally wrong to use animals in this way. The scientists put the animals through a numerous amount of painful tests. For example

medecines. There are other ways to get these results that would leave animals out of the picture and cost less. Alternative testing methods are readily available to scientists that include: petri dish testing, microdosing, artificial human skin, and Microfluidic chips (Animal Testing 2). Although nothing can accurately compare to a living breathing test subject these alternatives give a similar, if not identical, set of circumstances that a living subject might

Q1. explain briefly the difference between a) an agonist and antagonist –give 2 examples of each When the action of the drug is to activate or switch on a reaction, the drug is called an agonist. On the other hand, if the drug switches off the reaction, or inhibits or blocks the binding of other agonist components onto the receptor, it is called an antagonist. Hence, agonist and antagonist act in opposite direction, if agonist activate an action, antagonist inhibit an action(New Health Guide, 2014)

than animal testing because human cells can be used. Also with advancing technology, computers are able to determine toxicity of substances without requiring a single test on animals. Other alternative methods include artificial human skin, and microfluidic chips to represent human organ systems (Animal Testing). Thomas Hartung, Professor of evidence-based toxicology at Johns Hopkins University, argues for alternatives to animal testing because "we are not 70 kg rats" (Animal
