Use of the photoacoustic spectroscopy for surface characterization of nanometer-sized cobalt-ferrite particles

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

“…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]. 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.…”

“…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].…”
