Nanomedicine technology platform
The nanotechnology is a technology that uses methods like physical cutting and chemical synthesis to control the structure and shape of objects, thereby achieving nanometer size. It is a cross-disciplinary technology, and hence can be applied in a wide range of industries including chemical, energy, mechanical, electronics, biological, medical, pharmaceutical and beauty industries. In the medical and health field, nano-biotechnology has a wide range of application and a clear industrialization prospect, especially in areas like nanomedicine, nanomedicine carrier, nano-biosensors, imaging technology, and micro smart medical devices. It also plays an important role in disease diagnosis, medical care, and healthcare.
The nanotechnology provides a novel technology for the development of new drug and carrier in terms of designs to promote drug absorption, establish new drug control system, improve drug delivery, replace viral vector and produce auxiliary drug. In addition, it solves the issues that traditional medicine and technology could not resolve. The application of nanoparticles in pharmacy can be divided into nanomedicine and nano-carriers. The nanotechnology treatment can improve the bioavailability as well as uniformity, dispersibility, and absorption of agents. The application in nanomedicine delivery can dissolve insoluble drugs in water, or provide alternative routes of administration of drugs, or alter the absorption, dispersion, metabolism, and removal of the drug. It even allows for sustained release as well as targeted release. The development of nanomedicine in recent decades has a significant impact on the medical and healthcare industries. There are already more than 200 nanomedical products that have been reviewed or are undergoing clinical trials.
When a drug is combined with a suitable carrier, the carrier can release the drug at a specific site based on the demands of the treatment. With its small size and large specific surface area, the nano-carrier provides a new method for research on controlled drug release. An ideal nano-carrier should have the following properties, a greater load, a greater drug encapsulation, simple preparation and purification method that can be easily scaled up for mass production, biodegradable, low or no toxicity, appropriate size and shape and longer retention in the body. Recently, nano-carrier research has developed different carrier systems based on the properties and preparation method of the drug. The examples of such systems include nanoparticle, nanoliposome, solid lipid nanoparticle (SLP), nanosuspension and magnetic nanoparticle.
