Product Name
Name:a>Carboxylated dextran coated Fe3O4 nanoparticles
Product Overview
Technical Parameter
Particle: 5-20nm(TEM)
concentration：~1 mg/mL
Product Features
Superparamagnetism: Fe3O4 nanoparticles are superparamagnetic and can be rapidly magnetized and demagnetized under an external magnetic field. They are suitable for magnetic resonance imaging and magnetic hyperthermia. Carboxyl Functionalization: Surface carboxylation provides reactive chemical groups that facilitate covalent binding to drugs, biomolecules, or targeting ligands. Biocompatibility: Modification of carboxylated dextran improves the compatibility of nanoparticles with biological systems and reduces potential toxicity to normal cells. Stability: Modification of carboxylated dextran enhances the stability of nanoparticles in vivo and reduces the risk of aggregation and precipitation.
Application Fields
Magnetic Resonance Imaging (MRI): These nanoparticles can be used as MRI contrast agents to enhance imaging signals. Modification of carboxylated dextran improves its biocompatibility and stability in vivo, thereby improving imaging quality. Magnetic Hyperthermia (MHT): Fe3O4 nanoparticles can produce a thermal effect under the action of an external alternating magnetic field and can be used in magnetic hyperthermia therapy, especially in cancer treatment, to selectively kill cancer cells. Medication Delivery: Carboxylated dextran-modified ferric oxide nanoparticles can be used as drug carriers for drug delivery through their magnetism and the hydrophilicity of the carboxyl group. These nanoparticles can be combined with proteins or other biomolecules through covalent bonds to achieve targeted drug delivery. Biomolecular conjugation: The surface carboxyl functional groups of these nanoparticles can be coupled with biomolecules such as proteins, antibodies, and enzymes for biosensing and diagnosis.Nanoprobe construction: Carboxylated dextran-modified iron ferric oxide nanoparticles can be used to construct nanoprobes for biological detection and analysis.

Our dog loves them
Style: Latex Surpise Color, Size: 6"
Not for every type of dog, but our dog LOVES these things. Try one and see how it goes. They are cheap, so no great loss if your dog doesn't like it, But if it does, you'll have a great time with them. Best $3 I could spend

Tie a Knot in it if it rips
Style: Plush Surprise Color, Size: 6", Style: Plush Surprise Color, Size: 6"
My puppy split the middle belly seam in about 5 minutes of spirited play with the white foam and squeak assembly scattered about, but he loves these loofa toys - goes nuts for them. Went through a couple of the little $3 ones so I tried this big one which he ripped apart. But I tied a knot in the middle of it over the ripped part and guess what, it's better than before. He loves the whipping the big knot around. The part where it ripped was where they filled it I think but the rest of the stitching is really quite solid. Takes a beating, to a point. The little ones lasted a reasonable time before they were totally played.

A Humorous Twist on Tough Dog Toys!
Size: Large, Color: Lobster 3 Pack
I recently purchased the Nylabone Power Chew Dog Toy Pack for Aggressive Chewers from Amazon, and I must say, these toys have been a hilarious hit with my furry friend. As a dog parent of a strong and determined chewer, finding toys that can withstand their chewing prowess is a top priority, and these toys deliver both durability and a touch of humor.
The pack consists of three large/giant-sized toys in the shape of a lobster, cheese, and broccoli. The unique and amusing design puts a smile on my face every time I see my dog interacting with them. The unexpected twist brings a playful element to our daily playtime sessions, making it a fun and engaging experience for both of us.
When it comes to durability, these toys excel. My dog can be quite aggressive with their chewing, and I've struggled to find toys that can withstand their powerful jaws. However, the Nylabone Power Chew toys have proven to be impressively tough and durable. Despite rigorous chew sessions, these toys have remained intact, with no signs of wear or damage. They provide a reliable outlet for my dog's chewing instincts without the risk of shredding or ingesting any harmful materials.
The textured surfaces of these toys add an extra layer of interest for my dog. The ridges and raised bumps provide sensory stimulation, promoting healthy oral hygiene and helping to clean teeth and gums as they chew. I appreciate the added dental benefits these toys offer, as it helps maintain my dog's dental health while they engage in play.
I also appreciate the size options available in this pack. Large and giant-sized dogs often require bigger toys to accommodate their larger mouths and chewing strength. The included toys are appropriately sized for larger breeds, ensuring a comfortable grip and maximum enjoyment during play sessions.
As a bonus, these toys are made from high-quality, non-toxic materials, so I have peace of mind knowing that my dog can safely interact with them. Safety is a top priority for me, and Nylabone consistently delivers in that regard.
In conclusion, if you have an aggressive chewer and are in search of durable, funny, and engaging dog toys, the Nylabone Power Chew Dog Toy Pack is a fantastic choice. These toys provide hours of entertaining play, withstand even the most determined chewers, and offer dental benefits. Embrace the humorous twist and enjoy watching your furry friend engage in safe and engaging play with these fantastic toys.
Invest in the Nylabone Power Chew Dog Toy Pack today and let the lobsters, cheese, and broccoli bring laughter and durability to your dog's playtime!

Shark dog approved
Size: Large, Color: Broccoli, Size: Large, Color: Broccoli
My new baby shark.... I mean puppy really enjoys chewing. I can't just give her a ton of pig ears or bully sticks all day, which she would definitely love, so I'm constantly looking for well made chew toys. I'd put this right up with Kong. Very durable and nice. I also love the different textures, she seems to also love it. She can gnaw at the top and chew on the stem. She wanted it as soon as I opened it - it does smell like bacon but I haven't taken a chomp at it to be able to write a complete review!
My dog is about 23 lbs but I can see a 80 lb dog chew this, it's not small.
