Реферат:
Hydrophilic gold nanoparticles stabilized with isonicotinic acid (INA) were prepared by reduc
tion of HAuCl4 with sodium borohydride in the presence of INA in water, dimethylformamide, and dimethyl
sulfoxide. The main condition for the preparation of good quality particles is to maintain reagent concentra
tion ratio HAuCl4 : INA : NaBH4 = 1 : 2 : (5–10) at cAu ≤ 0.5 mM. Reaction products in water are mainly
spherical primary particles with gold nuclei of 2–7 nm in diameter, those in dimethylformamide are second
ary coalescent particles with nuclei of spheroid or slightly faceted shape 2–12 nm in diameter and larger elon
gated agglomerates from 15 to 100 nm long. Framework structures composed of chaotically agglomerated
particles were obtained at HAuCl4 : INA ratio larger than 1 : 2. By the example of precipitate of particles pre
pared in dimethylformamide and on the basis of data of chemical and thermal analysis, XPD, and IR spec
troscopy, it was shown that the product contains gold, INA anion, acetone, water, sodium cations, and oxy
gen boron compounds. The particles obtained as precipitate or concentrate are well redispersible in water and
polar solvents. The particles in colloid dispersions are in aggregated state and suffer gradual coagulation and
sedimentation, which are not irreversible, and dispersed state can be restored by ultrasound treatment. The
particles stabilized by INA may be of interest as initial product for preparation of nanomaterials for biomed
ical purposes.
