Integrated Nanoparticle–Biomolecule Hybrid Systems: Synthesis, Properties, and Applications

“…[21a, 74] Likewise, biotinylated CdSe-fragments of various immunoglobulins. [76] Also, NP-antibody conjugates were used for affinity binding of their respective antigens (Figure 2 E). [77] This may be advantageous because upon association with their respective antigens, nanoparticleconjugated antibodies can demonstrate association constants that are even higher than those of the free antibody.…”

Features of the stabilization of silver nanoparticles by carbonyl-containing polymers

“…The papers [13,44], in which the stabilizing effect of both the initial and of the partially decarboxylated PAA on the AgNP is investigated, are fundamental to the stabilization of AgNPs by carbonyl-containing polymers. The photochemical synthesis of AgNPs from the PAA-Ag + complex was studied.…”

“…Among stabilizers of polymeric type polyacrylic (PAA) and polymethacrylic (PMA) acids and their salts [13,14], polyacrylamide (PAAm) and its derivatives [15,16], polyalkyl(meth)acrylates [17,18], polyacrylonitrile (PAN) [19][20][21], polyamido acids (PAmA) [10], poly(N-vinyl-2-pyrrolidone) (PVP) [22][23][24], polyamides [25], polyamidoamines [26,27], polyurethanes (PU) [28], polyethyleneimine [29,30], polyaniline [31,32], poly(4-vinylpyridine) [33], polyvinyl alcohol (PVA) [34,35], polysaccharides [36,37], polyethers [38,39], polypeptides [40,41], polyether sulfones [42,43], and certain others have proved notably effective.…”

Formation of silver clusters by borohydride reduction of AgNO3 in polyacrylate aqueous solutions

“…The typical example is the so-called "blue silver," the product of the interaction between the silver clusters and the polyacrylate anion absorbing light in the range of 600-800 nm [2][3][4][5][6][7][8][9][10]. Systems with similar spectral properties are obtained by the radiation-induced reduction of AgClO 4 in alkaline wateralcohol solutions of polyacrylic acid [2][3][4][5], by the prolonged storage of γ -irradiated systems [4,6,8], by the reduction of silver cations with gaseous hydrogen [6], as well as by the photochemical reduction of AgNO 3 in polyacrylate aqueous solutions [9]. The exact composition and structure of these compounds existing at the initial stages of reduction are not established.…”
