The use of various pharmaceutical carriers to enhance the in vivo
efficiency of many drugs and drug administration protocols has been
well established during the last decade in both pharmaceutical
research and clinical setting. Surface modification of
pharmaceutical nanocarriers, such as liposome, micelles, na-
capsules, polymeric nanoparticles, solid lipid particles, and
niosomes, is normally used to control their biological properties
in a desirable fashion and to simulta- ously make them perform
various therapeutically or diagnostically important functions. The
most important results of such modification include an increased
stability and half-life of drug carriers in the circulation,
required biodistribution, passive or active targeting into the
required pathological zone, responsiveness to local physiological
stimuli, and ability to serve as contrast agents for various
imaging modalities (gamma-scintigraphy, magnetic resonance imaging,
computed tomography, ultra-sonography). Frequent surface modifiers
(used separately or simultaneously) include soluble synthetic
polymers (to achieve carrier longevity); specific ligands, such as
antibodies, peptides, folate, transferrin, and sugar moieties (to
achieve targeting effect); pH- or temperature-sensitive lipids or
polymers (to impart stimuli sensitivity); chelating compounds, such
as EDTA, DTPA, and deferoxamine (to add a heavy metal-based
diagnostic/contrast moiety onto a drug carrier). Certainly, new or
modified pharmaceutical carriers (nanocarriers) as well as their
use for the delivery of various drugs and genes are still described
in many publications.
