A New Way to Vanquish Biotechnology Products Deficit

Nanotechnology researchers are often troubled by lack of availability of biotechnology products. However, now research itself is being claimed to have found a solution.

Nanotechnology research is an ever growing area of science, and scientists working in its realm use a variety of substances to build atomic scale structures. To solve their problem of shortage of raw materials, scientists at the Arizona State University’ Biodesign Institute plan to use cells as manufacturing units to make DNA based nanostructures in a living cell.

Historically, biotech products have been produced by biotechnology companies by chemically synthesizing all of the products from scratch. And much of the process entails using different toolboxes to make varied DNA nanostructures and get them to attach and organize with other molecules viz. nanoparticles and other biomolecules.

However, now it is has been found that artificial nanostructures can be replicated using the mechanisms already present in live cells. The best part is that, you don’t have to manufacture cells, and also that nature itself has endowed them with the ability to making copies of double stranded DNA. The only thing scientists have to do is to get them to make complex DNA nanostructures like a copier machine does.

When going about brainstorming for the solution, scientists thought of using the cellular system as simple DNA can be easily replicated in a cell. But the problem was that they didn’t know whether the cells’ replicating mechanism would tolerate single stranded DNA nanostructures that house complex secondary structures or not? In the end it did.

Just the beginning though, this research appears to be quite exciting as in the future it may be used in synthetic biology applications. Perhaps as the technique is perfected, and when biotechnology companies and the biotech pharmaceutical industry implements the research full-on, there won’t be any dearth of biotechnology products for scientists and the medical industry.

Novel drug delivery technologies offer new potencies to come up with new solutions for new medical problems. Some of the novel drug delivery systems are as follows:

 

Self-emulsifying drug delivery  systems Nanotechnology-enabled formulations for delivery of poorly water-soluble drugs Innovative drug delivery  solutions for Biotech-derived products Sustained Release Formulations Micro/Nano particulate drug delivery  systems Intra-nasal drug delivery systems

 

There is also great advancement in such new drug delivery systems. For instance, transdermal drug delivery has the ability to make use of nanotechnology to increase concentration and bioavailability.

 

These types of drug delivery methods can be highly useful for patients suffering from central nervous system (CNS) or neurodegenerative disorders.

A primer on Drug Delivery Systems

The drug delivery industry has become one of the fastest emerging industries in the healthcare sector. Drug delivery refers to the delivery of pharmaceutical substances to animals or human beings. The modes of delivery can be nasal, oral or rectal. For the drugs to prove effective, it is very important to ensure that they work in a controlled manner and get distributed throughout the body in a proper way.

Targeted drug delivery occurs when the administered drugs remains active within a particular area of the body. Targeted drug delivery can prove very effective in controlling the rapid increase of cells leading to cancerous tissues.

Most recent attempts in the realm of drug delivery include

Sustained-release formulations (in which the physician administers or releases the drug over a certain period in a controlled manner) and
Advance in intended delivery (in which the administered drugs remain active only in the targeted region of the body.

New drug delivery systems hold greater promise, as they tend to lessen the manufacturing costs. In addition, they have a better targeting ability. Due to this, the patients won’t need to take high doses and so, will face minimum side-effects.

Transdermal drug delivery system, with the use of nanotechnology, can enhance the concentration and bioavailability of the drugs. Such a technology can prove to be a boon for patients suffering from Central Nervous System (CNS) or neurodegenerative disorders.

New drug delivery systems can alleviate some major concerns of the pharmaceutical industry and offer much better prospects of finding out new and better solutions for improving the current medical problems. Apart from Nanotechnology, some other drug delivery technologies are:

Sustained Release Formulations
Nano/ Micro particulate drug delivery  systems
Self-emulsifying drug delivery  systems
Intra-nasal drug delivery systems
Innovative drug delivery solutions concerning Biotech-derived products

One of the main objectives of drug development is to find drugs that will prove to be more effective in curing diseases and treating different medical conditions.

Quantum Dot’s Flexability Make them Useful in a Number of Areas

Many people have never heard of quantum dots, but they are an increasingly important part of nanotechnology. Quantum dots nanotechnology are approximately 5.5 to 6.5 nanometers in diameter. Nanometers are very small; equivalent to 1/1,000,000,000th of a meter. Though small, quantum dots are making a big difference in a number of areas including medicine, lighting, and solar energy.

Quantum Dots in Medical Technology

Quantum dots are being used in medical technology to track and monitor cell changes. Quantum dots are much brighter and more stable then their predecessors in medical technology, which were organic dyes. These benefits allow for much clearer results, and longer observation periods. Quantum dots are currently being used to track the development of cancer cells, so there’s a chance that the use of quantum dots in medicine could lead to better cancer treatments in the future.

Quantum Dots in the Home

Another use of quantum dots is in LED lights. LED stands for Light-Emitting Diode, and it is the newest technology in lights. Compact fluorescent bulbs are already more efficient than incandescent bulbs, and LED lights last four times as long and use half the energy of compact fluorescent bulbs. The biggest problem with LED lights is that they are new still a new technology, so the cost per bulb is still high. As with all new technologies, price goes down over time. This means that eventually LED lights will replace compact fluorescent bulbs as the light bulb of choice.

Quantum Dots in Solar Technology

A hot topic currently is solar energy, and quantum dots are being used in solar energy research as well. Much like how quantum dots are being used to improve LED lights, quantum dots are being used to improve solar receptors. Currently the theoretical limit for energy conversion is 33%, while using quantum dots increases the efficiency to approximately 60%. This is due to quantum dots’ ability to absorb and emit radiation. If the integration of quantum dots into solar receptors goes well it could be a major factor in solar panels becoming more mainstream and practical.

Drug Delivery System

Drug delivery refers to the delivery of a pharmaceutical substance to human beings or animals. Modes of delivery include oral, nasal and rectal. However, administration of drugs through these modes may lead to terrible conditions.

Therefore, physicians prefer to deliver several peptides and protein drugs through injections.

To work efficiently, the drugs have to act in certain controlled manner to distribute the drug in the body. Targeted drug delivery takes place when the drugs remain active within a specific region of the body. Targeted delivery is important when the drugs need to have an effect on rapid increase of cells that lead to cancerous tissues.

Recent attempts in the area of drug delivery include, advance in intended delivery where the drugs are only active in the targeted area of the body (for instance, in cancerous tissue) and sustained-release formulations wherein the physician releases the drug over a period in a certain controlled manner.

The main aim of drug development is to discover drugs that are more effective and help to cure several symptoms of medical condition or illness. Drug development is often required to discover the chemical properties of latest substances, their strength and chemical composition. It is also necessary for the process of drug development to meet the regulations laid down by the authorities who certify drugs.
