Product Features

Monodispersibility: The uniform particle size distribution of microspheres helps ensure consistency and reproducibility of experimental results.

Adjustable particle size: By controlling the synthesis conditions, microspheres with different particle sizes can be prepared to meet different application requirements.

Surface functionalization: The surface of microspheres can be chemically modified by introducing specific functional groups, such as carboxyl and amino groups, to achieve specific biochemical functions.

High stability: Microspheres have good chemical and physical stability and are suitable for use in various environments.


Application Fields

Biomedical research: used for cell labeling, imaging, and as a carrier for drug delivery systems in fields such as cell biology, molecular biology, and biochemistry.

Standard measurement: As an instrument calibration particle, used to calibrate analytical instruments and ensure measurement accuracy.

Biochip: In the field of biochar technology, it is used to construct high-density arrays of biomolecules.

Preparation of latex paint, color changing ink, and photonic crystal devices: monodisperse polystyrene microspheres can be used to prepare photonic crystal films with bright colors and color characteristics that change with observation angle

Squeaker not working!
Color: Yellow
I'll give it 3 stars because I love the design and it's sturdy and great for dogs to hold/launch. That said, the squeaker doesn't really work... I tried everything but it just doesn't make any sound. My dog wasn't really interested but when it did make a slight sound he approached it. Once it stopped he lost interest. But he's very difficult to please😆 so if you have a normal dog, he'll probably like it! I hope the manufacturer fixes the squeaker issue because apparently many people are having the same issue, which is a shame because the product is clearly well made! I'm on the fence about returning it just because the quality it's amazing(squeaker issue aside)!

Sturdy rubber ball. Noise maker could be improved
Color: Red
I would have given it five stars because of how much, my dog loved it in the beginning. And shut us up holds true as a sturdy rubber ball. My only complaint is at with one of my dogs being a heavy chewer, she was able to bust the noise making part. The ball never broke open or anything. It just no longer makes noise. You can hear the piece rattling on the inside. The ball itself is still solid tho

POOR QUALITY WHILE OVER PRICED
Color: Brown
Like so many others said, the sound box in this ball is faulty. lasted ONLY for 30seconds. My dog loves the giggle ball I purchased prior so I knew she would like this as well. Well, she did, for that whole 30 seconds. Both of us were so disappointed we could not further our play. Plus this ball was so much smaller than expected for the cost. I would not have minded the cost had this ball been on the ball! Don't purchase this item. Buy the giggle ball instead if you haven't already. UPDATE... Ran across this message at a later date and I would like to thank the sellers at Mewlmart for their response and showing the best business practices as stated in their response below. ----------------------- We sincerely apologize for any inconvenience regarding your order and would like to offer you a full refund for your purchase. If you would like a full refund: please reply 'Full refund'. We hope that you give us another chance. Thank you very much. Best regards, Mewlmart ----------------------- Only thing is I wish I had seen their message earlier, as I believe the window of opportunity for a refund may no longer be applicable. But who knows, they may reach out and still honor it when they review this review. Will update if that happens as it is worth mentioning the extra mile they may take. I am sure I would just then turn around and buy another product from them, giving them another try:)
