Biotechnology: The Future of Medicine and Agriculture

From using yeast to make bread and wines to creating vaccines for COVID-19, biotechnology has come a long way. It is a multidisciplinary science that has revolutionized biology and natural sciences technology forever. As scientists uncovered the secrets of molecular biology, we have seen plenty of its applications, of which, biotechnology is one of the breakthrough applications. In the following sections, we will learn about the meaning of biotechnology, its uses in agriculture and medicine, and its scope in the future. 

What is Biotechnology? 

Biotechnology is the science of using living organisms or their parts to create products or services useful for humans. For example, when you put a little curd in boiling milk to make curd. What you are essentially doing is using biotechnology. In this process, you are using lactobacillus bacteria to produce a product.  

The above example is a traditional approach to biotechnology. The modern meaning of biotechnology is a little more complex. It is based on the applications of molecular biology. Scientists use the principles of genetic engineering to produce products and services.  

Process of biotechnology: 

In biotechnology, a part of DNA or genetic material is replaced with the DNA fragment of some other organism like a virus or a bacteria having the desired traits. This new DNA is called recombinant DNA. It is an engineered product that can be used in many forms such as in the making of vaccines, as medicines, or producing genetically engineered vegetables and fruits. 

This is a breakthrough technology that has revolutionized the world. Biotechnology has changed the world in many sectors, especially medicine and agriculture. I will explain some of this in the next sections. 

Applications of Biotechnology in Medicine

The applications of biotechnology in the field of medicine are very vast. Some of these are: 

1. Personalized Treatment 

In cases of genetic diseases or tumors, personalized treatments can become miraculous. Doctors and oncologists can perform genomic profiling and provide targeted treatment as per their genome. This will help improve the patient’s survival rates and even increase the chances of complete recovery. 

2. Gene Therapy 

Gene therapy is another application of the biotechnology. In this, a disease is treated using recombinant DNA. A modified gene with a desirable genetic material is injected into the patient’s body. This can be done in two ways, by injecting a vector that is extracted from other living organisms like bacteria. Or changing the genetic material of the patient’s cells and then injecting that back into his/her body to produce desirable results. 

Gene therapy is still in its developing stages and has many drawbacks, but as this technology improves, it can prove to be life-changing for many. 

3. Bioprinting 

Three-dimensional bioprinting is a technology that is used to create living tissues by additive methods.  

We are aware of just how many people die each year due to chronic organ failures such as chronic kidney diseases, chronic liver disease chronic lung disease etc. By manufacturing artificial organs using 3D bioprinting, we can save the lives of thousands of people. It is becoming a new hope for the people on the waiting lists for organ transplants. This technology when developed fully will become a miracle for humans by revolutionize healthcare. 

We can also use bioprinting to test for new drugs and therapies on living tissues. This will increase and improve the efficiency and quality of the process.  

There are many other benefits of this technology such as skin regeneration, drug inventions invitro studies, etc. 

4. Immunotherapy 

It is a type of therapy that is given to patients to improve their immune systems so that the body can fight against diseases. In this therapy, patients are administered specific drugs vaccines or antibodies that help the patient’s body fight against diseases by itself. This type of therapy proves to be a great treatment in case of severe diseases like cancers. Biotechnology can play a significant role in this as it can help make drugs that are targeted towards a specific type of genetic makeup or create vaccines faster and more efficiently. 

5. Nanoparticle-based Therapy 

Nanoparticle-based therapy means using nanoparticles to deliver drug therapy to patients. Nanoparticles can be delivered to a specific place without hurting other areas. It can also be used in many other areas, such as treating cancer, diagnosing genetic disorders, etc. 

Applications of biotechnology in Agriculture

1.  Climate Change 

As climate change is becoming a very serious issue in today’s world, we are trying to find ways to solve this crisis. For this, biotechnology can provide very good solutions. With the help of biotechnology, we can develop crops that can reduce emissions and increase in capture of carbon dioxide. 

2. Food Security 

One of the most important applications of biotech is providing food security. Biotechnology has helped us create food that has more nutrient reserves, is more tolerant towards climatic and biotic stress, etc. This helps increase food security in the world and makes sure we have enough food resources for everyone.  

3. Urban Agriculture 

With the development happening in parts of the world, more and more traditional agricultural land is turning into urban areas. This can pose a challenge to the people in the coming times. That is why this concept of urban agriculture is becoming increasingly important. Urban agriculture means growing crops in urban areas like balconies, rooftops, home gardens, etc.  

Principles of biotechnology can help create crops that are more tolerant to grow in urban areas, have higher nutritional contents, and are less likely to get damaged by pests. 

4. Controlling Pollution 

In today’s world, every aspect of our environment is suffering from pollution. Be it air, water, or soil, every area is dealing with the impacts of pollution. We can use biotechnology to fight and control this. Such as using microorganisms that can convert the toxic particles in the environment into harmless byproducts.
