Raman spectroscopy of cobalt ferrite nanocomposite in silica matrix prepared by sol–gel method

Hybrid Nanoscale Magnetic Composites

“…ION surface modification can be carried out by attachment of organic molecules aiming at the stabilization of the nanoparticle in biological media and to provide functional groups at the nanoparticle's surface that are free to attach to biological agents 46,47 and/or to avoid immediate uptake by the reticuloendothelial system (RES). 51 These nanocomposites can be synthesized on large scale and have been extensively investigated from the physical, chemical and biological points of view, thus supporting technological applications in different fieldsl. 48 Otherwise, synthesis of iron oxide nanoparticles have been conducted within a polymer solution.…”

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

“…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

“…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]. In particular, Mössbauer [1][2][3][4][5][6][7][8][9][10] and Raman [28,29] nanoparticles co-precipitated in alkaline medium at 2,700 rpm. The left panel of the inset is a representative TEM picture of the sample.…”

“…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].…”
