“…Under the influence of the electric field, the charged particles move towards the oppositely charged electrode and are deposited onto the substrates, forming a relatively dense and homogeneous compact particles. [5][6][7] Over the past few decades, there have been considerable interests in developing biodegradable nanoparticles as effective drug delivery carriers. Various polymers have been used in drug delivery research that can effectively deliver the drug to a target site and increase the therapeutic effect, while minimizing any side effects.…”

Restenosis after percutaneous coronary intervention (PCI) continues to be a serious problem in clinical cardiology. To solve this problem, drug eluting stents (DES) with antiproliferative agents have been developed. Variable local drug delivery systems in the context of stenting require the development of stent manufacture, drug pharmacology and coating technology. We have worked on a system that integrates electrophoretic deposition (EPD) technology with the polymeric nanoparticles in DES for local drug delivery and a controlled release system. The surface morphology and drug loading amount of DES by EPD have been investigated under different operational conditions, such as operation time, voltage and the composition of media. We prepared poly-D,L-lactide-co-glycolic acid (PLGA) nanoparticles embedded with curcumin, which was done by a modified spontaneous emulsification method and used polyacrylic acid (PAA) as a surfactant because its carboxylic group contribute negative charge to the surface of CPNPs (−53.5 ± 5.8 mV). In the process of 'trial and error' endeavors, we found that it is easy to control the drug loading amount deposited onto the stent while keeping uniform surface morphology. Accordingly, stent coating by EPD has a wide application to the modification of DES using various kinds of nanoparticles and drugs.

“…A recent study demonstrates that dispersion depends on the I 2 -solvent interaction [37], while results in table 1 verify that the amount of I 2 for each system solvent-particle should be optimised. In fact, the surface charge of the particles becomes positive whatever was their nature [19,[33][34][35][36][37][38][39][40][41][42][43][44], and the effective amount of I 2 added is related to the morphologic properties of the particles [38,58,85].…”

Moreover, I 2 has been also used as dispersing agent in other organic solvents, such as acetilacetone (AcAc) [45][46][47][48], isopropanol (IPA) [49][50][51] or a mixture of acetone (Ac) or acetilacetone and ethanol (EtOH) [37,42,[52][53][54][55].…”

Electrophoretic Deposition (EPD) performance strongly depends on the particles surface chemistry and the ability to manipulate surface-liquid interfaces. In this study an extensive investigation of YBCO suspension in dry acetone, acetone-water mixtures and acetone-iodine is reported. Chemical instability of YBCO particles determines their colloidal behaviour. Charging mechanism of particles has therefore had to be deeply investigated for complete dispersion understanding. In order to determine the conditions of the YBCO suspension stability, measurements of pH, conductivity, zeta-potential, settling tests, modelling of the particle networks and electrophoretic deposition were done. The influence of the water and iodine concentration, and their role as stabilizers was evaluated. Based on experimental results, pair particle potentials were calculated and then different charging mechanisms of YBCO surfaces in acetone were proposed.

This study presents dielectric and piezoelectric properties of piezoelectric thick film processed by electrophoresis deposition method. 1¯m200¯m-thick film were fabricated by electrophoresis depostion method. The dielectric constant and piezoelectric property of the piezoelectric film increased as the film become thicker. When electric field <3 kV/mm was applied, their dielectric and piezoelectric properties were changed with respect to their thickness. At electric field = 5 kV/mm their properties are constant regardless of their thickness. These changes can be explained by existence of many void defects to be inevitabley introduced in thick film fabrication process, which can be one of crucial causes of controlling ferrroelectric properties of thick films.
