Birefringence of maghemite-based magnetic fluid in the highly concentrated regime

Magnetic resonance study of maghemite-based magnetic fluid

“…2). We found n MR E1.01n TEM , despite the existence of a fraction of chain-like structures as already observed using static magnetic birefringence (SMB) data [14]. Different techniques have been used to probe, directly [15] or indirectly [16], chain-like structures in MF fluid samples exposed to magnetic fields.…”

Photoacoustic spectroscopy as a key technique in the investigation of nanosized magnetic particles for drug delivery systems

“…Different optical and magneto-optical techniques have been used to investigate nanosized magnetic particles either as a pure powder sample, suspended as a colloid, or dispersed in a hosting template. For instance, the widely used static magnetic birefringence is an exceptional technique in the investigation of MFs, once it provides information regarding the degree of nanoparticle agglomeration [17][18][19][20]. Also, Mössbauer [26][27][28][29][30][31][32] and Raman [21][22][23] spectroscopies, combined or not, have been extremely useful in probing cubic ferrite-based nanoparticles in regard to their size, chemical stability, surface characteristics, cation distribution, and phase identification.…”

“…response to DC/AC magnetic fields [13][14][15][16][17][18][19][20], visible/microwave excitation [21][22][23][24][25], and Mössbauer spectroscopy [26][27][28][29][30][31][32]. Applications of the l-MDDS discussed in this paper include cell-labeling [33][34][35], photodynamic therapy (PDT) [36][37][38][39][40][41], and magnetohyperthermia (MHT) of cancer cells and tissues [42][43][44].…”

Using Mössbauer spectroscopy as key technique in the investigation of nanosized magnetic particles for drug delivery

“…Different optical and magneto-optical techniques have been used to investigate nanosized magnetic particles as a pure powder sample, suspended as a colloid, or dispersed in a hosting template. For instance, the widely-used static magnetic birefringence is an exceptional technique in the investigation of magnetic fluids, once it provides information regarding the degree of nanoparticle agglomeration [22][23][24][25]. The recently used photoacoustic spectroscopy proved to be an excellent experimental technique to access information related to the molecular species attached to the nanoparticle surface [26,27].…”

“…This paper is focused on the description of the basic characterization of magnetic nanoparticles used to built a whole family of DDS, namely biocompatible magnetic fluids, magnetoliposomes, biocompatible magnetic nanocapsules, and biocompatible magnetic nanoemulsions. Besides Mössbauer spectroscopy [1][2][3][4][5][6][7][8][9][10] other techniques used to characterize the above-mentioned magnetic DDS include those related to the morphological/crystalline aspects [11][12][13][14][15][16][17], the magnetic and magnetooptical response to DC/AC magnetic fields [18][19][20][21][22][23][24][25], and visible/microwave excitation [26][27][28][29][30][31][32]. Applications of the l-DDS discussed in this paper include cell-labeling [33][34][35], photodynamic therapy (PDT) [36][37][38][39][40], and magnetohyperthermia (MHT) of cancer cells and tissues [41][42][43][44].…”
