of different situations where a fluid is in relative motion to a surface (the definition ofthe Reynolds number is not to be confused with the Reynolds Equation or lubrication equation). These definitions generally include the fluid properties of density and viscosity, plus a velocity and a characteristic length or characteristic dimension. This dimension is a matter of convention - for example a
particles (i.e. for
oral drug delivery) have been found to accumulate in the liver. Excessive immune/ inflammatory responses cause permanent liver damage.
Asbestos
Asbestos is a highly-fibrous mineral with long, thin, separable fibers.
Properties
heat-resistance, low electrical conductivity, flexibility, and high tensile strength were essential factors
The toxic properties of
the growth properties ofthe gold nanorods, namely their kinetics and anisotropic growth. In the case ofthe first parameter, we observed that slowing the growth ofthe Au nanorods increases their aspect ratio. In other words, anisotropic growth can be facilitated at low temper- ature. Recently, it has been found that a range of ordered superstructures ofparticles can be obtained by similar self
*’Nano’ means….
Nanometer: one billionth of a meter
Nano-: prefix comes from the Greek word for ‘dwarf’
Chemical, physical, and biological properties that differ from those oftheir larger, or bulk counterparts
Nanotechnology: The National Nanotechnology Initiative(NNI)-> the science of materials and phenomena in the range of 1 to 100nm in diameter

the drug before it reaches to the target.
For enhancing the efficiency of drug delivery system, we can use nanotechnology, especially nanoparticles that can carry the drug molecules to the target safely.
5.2.2 Nanocarriers - Nanoparticles
Before starting with the functionalization of nanoparticles, it is important to keep in mind a range of useful properties we wish to have in any drug
