Biopure Silver nano sphere

BIOPURE SILVER NANOSPHERES – BARE (CITRATE)

DESCRIPTION

Citrate is one of our most popular surface options; the “bare” surface is ideal for displacement with other molecules or ligands. 

BioPure materials are high quality, unagglomerated, and monodisperse nanoparticles. Extensively purified and provided sterile with low endotoxin. Ideal for in-vivo and in-vitro studies and medical applications. 

Additionally, our 75 nm BioPure Silver Citrate and 10 and 75 nm BioPure Silver PVP can be used as OECD standards for nanotoxicology testing.

CONCENTRATION & SOLVENT

Provided at 1 mg/mL in a 2 mM sodium citrate solution

AVAILABLE DIAMETER

5 nm, 10 nm,  20 nm, 30 nm, 40 nm, 50 nm, 60 nm, 70 nm, 75 nm, 80 nm, 100 nm, 200 nm

AVAILABLE VOLUME

1 mL, 5 mL, 10 mL, 30 mL

BIOPURE SILVER NANOSPHERES – BPEI (IMINE FUNCTIONALIZED)

DESCRIPTION

Branched Polyethylenimine (BPEI) is a 25 kDa polymer which contains a large number of free amines on the particle surface that are available for charge interactions with other target biomolecules or substrates.

BioPure materials are high quality, unagglomerated, and monodisperse nanoparticles. Extensively purified and provided sterile with low endotoxin. Ideal for in-vivo and in-vitro studies and medical applications. 

CONCENTRATION & SOLVENT

Provided at 1 mg/mL in water.

AVAILABLE DIAMETER

40 nm, 50 nm, 60 nm, 80 nm, 100 nm, 200 nm

AVAILABLE VOLUME

1 mL, 5 mL, 10 mL, 30 mL

BIOPURE SILVER NANOSPHERES – Carboxyl (Lipoic Acid)

DESCRIPTION

Carboxyl (lipoic acid) is covalently bound to the metal surface with a dithiol which forms a strong, stable bond to the metal surface. The acid provides a highly negatively charged surface.

BioPure materials are high quality, unagglomerated, and monodisperse nanoparticles. Extensively purified and provided sterile with low endotoxin. Ideal for in-vivo and in-vitro studies and medical applications. 

CONCENTRATION & SOLVENT

Provided at 1 mg/mL in water.

AVAILABLE DIAMETER

 40 nm, 50 nm, 60 nm, 80 nm, 100 nm, 200 nm

AVAILABLE VOLUME

1 mL, 5 mL, 10 mL, 30 mL

BIOPURE SILVER NANOSPHERES – PEG

DESCRIPTION

Polyethylene Glycol (PEG) is a 5 kDa ligand that is covalently bound to the particle’s surface. The PEG surface provides the highest stability in aqueous buffers and protic solvents.

BioPure materials are high quality, unagglomerated, and monodisperse nanoparticles. Extensively purified and provided sterile with low endotoxin. Ideal for in-vivo and in-vitro studies and medical applications. 

CONCENTRATION & SOLVENT

Provided at 1 mg/mL in water.

AVAILABLE DIAMETER

 40 nm, 50 nm, 60 nm, 70 nm, 80 nm, 100 nm

AVAILABLE VOLUME

1 mL, 5 mL, 10 mL, 30 mL

BIOPURE SILVER NANOSPHERES – PVP

DESCRIPTION

Polyvinylpyrrolidone (PVP) is a large polymer that offers excellent steric stability. Great choice for withstanding a broad range of salt, pH, and solvent conditions.

BioPure materials are high quality, unagglomerated, and monodisperse nanoparticles. Extensively purified and provided sterile with low endotoxin. Ideal for in-vivo and in-vitro studies and medical applications. 

CONCENTRATION & SOLVENT

Provided at 1 mg/mL in water.
