Physico-chemical properties of the C 60 - l -lysine water solutions

The use of nanocluster polyoxometalates in the bioactive substance delivery systems

“…This aspect makes fullerenes promising candidates as means of targeted drug delivery. However, fullerenes are hydrophobic, which limits the possibilities of their direct use in biomedicine [193] It is possible to obtain their aqueous dispersions [194][195][196][197][198][199][200] and associates with organic compounds [200][201][202][203][204][205]. One of the ways of modifying the surface of fullerenes provides hydroxylated derivatives such as fullerenols [195,200,205,206,208].…”

“…The absorption of such systems by cells can be realized through specific endocytosis. Another possible trend in the use of fullerenes is the creation of bioactive [203,204,206,208] or contrast materials for nuclear magnetic resonance imaging (MRI) through internal functionalization by contrast agents, including Gd 3+ , Sc 3+ , Ho 3+ , Tm 2+ , Ga 3+ and Tc 2+ ions, with isolation of unstable and potentially toxic contrast materials from the internal medium of the body [209][210][211][212]. A similar solution for creating contrast materials is proposed in [213] for Keplerates, the non-carbon analogs of fullerenes which form ionic associates with cations of the above-mentioned metals.…”

Cryometry and excess functions of the adduct of light fullerene C60 and arginine – C60(C6H12NaN4O2)8H8 aqueous solutions

“…Visible light scattering analysis in C 60 (C 6 H 12 NaN 4 O 2 ) 8 H 8 -water solutions (as well as in light fullerenols (trismalonates)-water solutions) at room temperature was provided repeatedly (see [1,5,14]). In all cases, one can observe the following:…”

“…This article is a continuation in the series of articles devoted to the synthesis, identification and physico-chemical properties investigation of nanoclusters, which represented the fairly water soluble derivatives of light fullerenes C 60 and C 70 [1][2][3][4][5][6][7][8][9][10][11][12][13][14] -poly-hydroxylated fullerenols fullerenol-d C 60 (OH) 24±2 and malonic ether -trismalonate C 70 [=C(COOH) 2 ] 3 . In previous articles, the authors have reported on the volume, refraction, electrical, transport properties of water soluble nanoclusters and their aqueous solutions.…”

Solubility phase equilibrium in ternary system fullerenol C60(OH)24 and praseodymium salt: PrCl3-C60(OH)24-H2O at 25 C

“…This article continues the cycle of publications, concerning the synthesis, identification and physico-chemical, physical, bio-chemical, biological properties investigation of the amino-acid-light fullerene adducts [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19]. This article is devoted to the investigation of the solubility diagram for systems containing water soluble fullerene nanoclusters, inorganic salt, including rare earth metals and actinoids, and water, as the solvent [20][21][22][23][24].…”
