Nanoparticles, the most widely used nanotechnology platforms in nanomedicine, are particles with two or more dimensions on the nanometer scale, according to the American Society for Testing and Materials (ASTM). Nanoparticles are materials with overall dimensions in the nanoscale, ie, under 100 nm. This substance prevents white blood cells (immune cells) from recognizing nanoparticles as foreign matter, which will allow these molecules and their drug to pass through the blood without intercepting the immune system. Nanomaterials are defined by Recommendation 2011/696/EU as unbound or aggregate particles where at least half of the particles have external dimensions of 1-100nm. Nanotechnology looks likely to revolutionize medicine in the future. INTRODUCTION Nanotechnology is a part of science and technology about the manipulation of matter on atomic and molecular size.

Nanotechnology in medicine involves applications of nanoparticles currently under development, as well as longer range research that involves the use of manufactured nano-robots to make repairs at the cellular level (sometimes referred to as nanomedicine). The modern form of a drug delivery system should minimize side-effects and reduce both dosage and dosage frequency. Although the definition identifies nanoparticles as having dimensions below 0.1 μm or 100 nm, especially in the area of drug delivery relatively large (size >100 nm) nanoparticles may be needed for loading a sufficient amount of drug onto the particles. Nanomaterials are at the leading edge of the rapidly developing field of nanotechnology. Titanium dioxide (titanium(IV) oxide, titania, TiO2) is an inorganic compound that owes its recent rise in scientific interest to photoactivity. They are polymer nanoparticles that In fact, during Feynman's first foray into the area, in his talk to the American Physical Society entitled 'There's Plenty of Room at the Bottom', he said 'although it is a very wild idea, it would be interesting in surgery if you could swallow the surgeon. Nanotechnology is the understanding and control of matter generally in the 1–100 nm dimension range. in wound healing, arthritic disease, etc. The interactions between nanoparticles and various cells and tissues of the human body will ultimately determine the medical applicability of the technology , .The interactions between nanoparticle design and various levels of biological complexity are presented in Fig. Nanotechnology driven innovations have given a hope to the patients as well as physicians in solving the complex medical problems. But what are lipids? Nanotechnology is the use and control of very small structures that are 1 to 100 nanometres in size. The small size of nanoparticles is especially advantageous in medicine; nanoparticles can not only circulate widely throughout the body but also enter cells or be designed to bind to specific cells. How Do Nanoparticles Get to the Right Spot in the Body? Medical applications include special materials for wound dressings and surgical textiles, materials used in … Nanomedicine involves the use of nanoparticles for therapeutic and diagnostic purposes. Lipid nanoparticles are small spherical particles made of lipids into which various “payloads” (in the case of the COVID-19 vaccines, mRNA encoding the SARS-CoV-2 spike protein) can be introduced. Their unique size-dependent properties make these materials superior and indispensable in many areas of human activity. The two vaccines both contain mRNA wrapped in lipid nanoparticles (LNPs) that help carry it to human cells but also act as an adjuvant, a vaccine … ). To go where ‘no man has gone before’ is no longer exclusively on an interstellar scale, but now on an microscopic scale as well. Lipid nanoparticles are a vital component of the new Pfizer/BioNTech and Moderna mRNA COVID-19 vaccines, playing a key role in protecting and transporting the mRNA effectively to the right place in cells.
