The integration of nanotechnology in modern medicine has been promising as tiny particles are carefully engineered to deliver drugs precisely. This type of innovation is known as nanotechnology-based drug delivery systems and could promote new ways to treat diseases, especially neurological disorders.

How do Nanotechnology-Based Drug Delivery Systems work?

They use nanoparticles, nanometer carriers, that can carry medicine inside or on their surface. These particles allow scientists to model them to bind with specific receptors or regenerate tissues. Additionally, nanoparticles can be designed to pass through small barriers and deliver drugs more effectively than traditional treatments.

Types of Nanoparticles:

• Lipid-based nanoparticles: Fat-composed particles used to carry drugs or genetic materials through the bloodstream

• Polymeric nanoparticles: Biodegradable polymers that release drugs as they break down

• Dendrimers: Branched molecules with multiple surface sites for targeting

• Inorganic nanoparticles: Metal-composed particles used for delivery and medical imaging

Cons and Risks:

• Immune system could remove nanoparticles too quickly, reducing its effectiveness

• Some materials or breakdown products from the particles could be toxic to the body

• Developing nanoparticles at a large scale is hard and expensive

• These systems tend to be complex, making it hard for them to be regularly used by hospitals as treatment

Nanotechnology-based drug delivery systems seem very promising and cool as they inject tiny particles into the body to treat diseases. However, they require more testing and clinical trials in order to be implemented in the healthcare system.
