Abstract:
The present disclosure is directed to methods of preparing stable suspensions of precious metal nanoparticles and methods for attaching bio-molecules to the nanoparticles. The formation of nanoparticles can be accomplished by either chemical synthesis or pulsed laser ablation in a liquid. The present disclosure reveals the importance of controlling the conductivity of the dispersion medium during pulsed laser ablation in a liquid to control the particle size of the nanoparticles. The present disclosure also reveals the importance of adjusting and maintaining the conductivity in a range of 25 μS/cm or less during storage of the nanoparticles and just prior to performing bioconjugation reactions. The control of conductivity is an important process for maintaining the nanoparticles as a stable non-aggregated colloidal suspension in a dispersion medium.

Orthoborate salts suitable for use as electrolytes in lithium batteries and methods for making the electrolyte salts are provided. The electrolytic salts have one of the formulae (I). In this formula anionic orthoborate groups are capped with two bidentate chelating groups, Y1 and Y2. Certain preferred chelating groups are dibasic acid residues, most preferably oxalyl, malonyl and succinyl, disulfonic acid residues, sulfoacetic acid residues and halo-substituted alkylenes. The salts are soluble in non-aqueous solvents and polymeric gels and are useful components of lithium batteries in electrochemical devices.
