surface area of the conductor plates and inversely proportional to the separation distance between the plates. If the charges on the plates are +Q and −Q, and V gives the voltage between the plates, then the capacitance is given by
C= Q/V
SI unit of capacitance is the farad; 1 farad is 1 coulomb per volt. Capacitance can be calculated if the geometry of the conductors and the dielectric p

surface, improved solubility, targeted drug delivery and multifunctionality, nanoparticles have emerged as potential drug delivery carriers to tissues throughout the body. Yet passing the BBB is particularly difficult. The proper design of such engineered ‘nanocarriers’ becomes very important in transversing the impermeable membranes to facilitate drug delivery. At the same time, it is also r
