Preparation and characterization of thermal-sensitive ferrofluids for drug delivery application

Preparation and characterization of magnetic phase-change microcapsules

“…Therefore, the distribution of iron nano-particles in the shell of magnetic phase-change microcapsules occurs in two different situations: (i) On the shell surface (ii) wrapped by the urea-formaldehyde resin. The results are consistent with those of Song et al [12] . The SEM micrographs illustrate that the particle diameter distribution is uniform and the paraffin is completely encapsulated, although the surface appearance of the magnetic phase-change microcapsules is coarser.…”

Preparation and characterization of Saccharomyces cerevisiae alcohol dehydrogenase immobilized on magnetic nanoparticles

“…Magnetic particles ranging from nanometer to micrometer scale are being used in an increasing number of applications such as the immobilization of proteins, peptides and enzymes [4][5][6][7], bioseparation [8], drug delivery [9,10], biosensor [11] and so on. In the recent years, the nanosized magnetic particles receive increasing attention because of their higher specific surface area for immobilization of higher amount of enzymes, superparamagnetic for reduce of self-aggregation and easy separability from reaction mixture by the application of a magnetic field [12,13].…”

“…Ferrofluids have attracting application in various fields like automobiles, electrical engineering [28,30,31,32], space technology, computer science, med ical imaging, bio med ical [3,4], targeted drug delivery [5,6], optical fiber [27,29] and sensors [7,8] etc. The temperature sensitivity issue on ferrofluid has already been studied [9,10]. Attempts have been made for generating energy fro m ferrofluids whereas, micro devices are used for fabrication and generation of energy.…”
