“…To date, numerous magnetic particles including magnetite, cobalt ferrite, Fe/Pt, and Fe@FeO have been successfully encapsulated into polymeric nanofibers where the principle of electrospinning remains similar. Most of these previous studies focused primarily on the production and characterization of magnetic fibers [18][19][20][21]. However, studies taking advantage of the potential of local heat-generating capability of magnetic electrospun nanofiber composites upon application of alternating magnetic field for hyperthermia treatment are limited [17,22].…”

“…Electrospinning is a technology used for the preparation of micro-and nanofibers with a length of up to several tens of meters. Because of the various morphologies, large specific surface area and porous structure, mats find application in medicine (mats with antitumor, antibacterial or hemostatic activity), pharmacy (drug carriers), for immobilization of enzymes for water purification or for the preparation of fibrous materials with magnetic properties [1][2][3][4][5][6]. Electrospraying allows the fabrication of micro-and nanoparticles, which can serve as drug carriers for the preparation of micro-and nanofilms for electroencapsulation, in direct electrowriting, etc.…”

Abstract. Microfibrous materials with a targeted design based on poly(L-lactic acid) (PLA) and poly(!-caprolactone) (PCL) were prepared by electrospinning and by combining electrospinning and electrospraying. Several approaches were used: (i) electrospinning of a common solution of the two polymers, (ii) simultaneous electrospinning of two separate solutions of PLA and PCL, (iii) electrospinning of PLA solution in conjunction with electrospraying of PCL solution, and (iv) alternating layer-by-layer deposition by electrospinning of separate PLA and PCL solutions. The mats were heated at the melting temperature of PCL (60°"), thus achieving melting of PCL fibers/particles and thermal sealing of the fibers. The mats subjected to thermal treatment were characterized by greater mean fiber diameters and reduced values of the water contact angle compared to the pristine mats. Heat treatment of the mats affected their thermal stability and led to an increase in the crystallinity degree of PLA incorporated in the mats, whereas that of PCL was reduced. All mats were characterized by enhanced mechanical properties after thermal treatment as compared to the non-treated fibrous materials.

“…Figure 10 shows the magnetization curves of the MC-PCL-M 1,3,6 hydrogel films measured at 300 K. The magnetization curves showed that the MC-PCL-M 1,3,6 hydrogels were superparamagnetic with no hysteresis and coercivity at room temperature. This characteristic property belongs to superparamagnetic nanoparticles that the thermal fluctuations are sufficient to prevail the anisotropic energy barrier [64,65].…”

ABSTRACT5-Fluorouracil loaded magnetic field sensitive methylcellulose and polycaprolactone gels were prepared and characterized by FTIR, XRD, TGA, SEM, and VSM. Swelling analysis supplied important information on drug diffusion properties. The release profile of gels was investigated in different buffer solutions and the highest release values were observed at pH ¼ 7.2. Release kinetic was analyzed using an empirical equation to clarify the transport properties of drug. The effects of nanoparticle concentration and applying external magnetic field were investigated on release profile. The results indicated that the drug release decreased by both, applying external magnetic field and increasing the concentration of Fe 3 O 4 nanoparticles. GRAPHICAL ABSTRACT ARTICLE HISTORY
