Name:Streptavidin-modified Fe3O4 particles

Product Overview

Streptomycin modified iron oxide particles are modified with streptavidin on the basis of iron oxide particles. The high affinity binding between biotin and streptavidin is the basis for the development of this field. Biotin is a small molecule that can be covalently attached to various biomolecules, while streptavidin can specifically recognize and bind to biotin.


Technical Parameter

Form: Solution

Diameter: 40nm, 100nm (customizable)

Ingredients: SA@Fe3O4 Ultra pure water


Product Features

High biocompatibility: The surface modification of iron oxide particles gives them good compatibility in biological systems.

High sensitivity: Due to the high affinity between streptavidin and biotin, these particles exhibit high sensitivity in detection applications.

High specificity: The streptavidin biotin system provides highly specific binding.


Application Fields

Biosensing: Utilizing the high affinity between streptavidin and biotin, SA@Fe3O4 Particles can serve as biosensors for detecting the interactions of biomolecules.

Magnetic resonance imaging (MRI): Due to the magnetism of iron oxide, SA@Fe3O4 Particles can be used as contrast agents for MRI, improving the contrast and resolution of imaging.

Cell separation and enrichment: By utilizing the magnetism of magnetic nanoparticles, specific types of cells can be easily separated and enriched from complex samples.

Fun toy
Pattern Name: Checkered
This was a very fun toy but didn't last too long with our 1-year-old lab who is an aggressive chewer.

Your fur kid will thank you!
Color: Yellow Green, Size: 6 Inch
My dog absolutely LOVES this toy! I recently adopted a rescue & wasn’t sure what she might like, so I bought this in a 6” size for a 50# shep/lab/hound. The ball comes with a cute little pump with needle which only takes a few seconds to inflate. I put the ball outside for her; she wasn’t sure of it at first but it didn’t take her long to realize how fun it was to throw around & chase. She throws it up in the air by the loops & runs all over the yard with it & it’s so comical to watch! It seems pretty durable & well made - I’m shocked she hasn’t punctured it by now, but if she does I will definitely buy her another….and another. This is easily her favorite toy. I highly recommend it for your fur kid - you won’t be disappointed, & neither will they..

First ball was great!
Color: Black Green, Size: 8 Inch
This ball was great! My dog loves it. I ordered another smaller one. It had no pump and the inside was separated from the outside piece so it couldn’t be pumped up.

Fun and durable
Color: Flag, Size: 6 Inch, Color: Flag, Size: 6 Inch
I have a 5 month old teething Whippet puppy and this toy is a favorite. She loves carrying it around by the straps, playing tug, and trying to chew it. I think it’s pretty tough and durable for someone her size. I could see how a shepherd might destroy it quickly, though. I was surprised to find you have to inflate it, but the pump and needles are included and it hasn’t lost any air over several days of rough play. (I kick it and toss it to her. We tug with the straps. She carries it everywhere.) The material feels like a heavy duty soccer ball, just smaller. It’s the perfect size for her. I’d definitely buy it again.
