The Effect of Biocompatible Coating Layers on Magnetic Properties of Superparamagnetic Iron Oxide Nanoparticles

Functionalisation of nanoparticles for biomedical applications

“…Procedures for the preparation of Au NP structures include seed mediated growth and sacrificial reduction. In seed mediated growth, Au ions are reduced in the presence of the NP cores requiring alteration [86,129,130]. However, where TEM evidence is presented nucleated nano-structures are formed.…”

“…There is also evidence that non-magnetic shells can alter the physical and chemical nature (i.e. oxidation states) of atoms in the core of the NPs [129,156].…”

State of the Art of the Bi- and Trimetallic Nanoparticles on the Basis of Gold and Iron

“…In some reports, the term "SPION" ("superparamagnetic iron oxide Nps") was used [85]. Thus, SPION-type Fe oxide Nps (6 nm diameter) were prepared by controlled chemical coprecipitations and further coated with Au starting from FeCl 2 , FeCl 3 , and HAuCl 4 as precursors in the system CTAB (cetyltrimethylammonium bromide)/octane/butanol/water [86].…”

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].…”
