Product Name

Name:Amino modified green fluorescent polystyrene microspheres


Product Overview

Carboxyl modified green fluorescent polystyrene microspheres are prepared by adding green fluorescent dyes with a fluorescence wavelength of 498-516nm and modifying them with carboxyl groups during the preparation of polystyrene microspheres. Customizable size range of 20nm-5 μ m. These microspheres have a uniform particle size distribution, which enables them to exhibit consistent performance in various applications. Fluorescent dyes are embedded inside the microspheres, effectively preventing fluorescence quenching and reducing the influence of environmental factors on fluorescence intensity.


Technical Parameter

Appearance: yellowish lotion colloid

Fluorescence wavelength: 498-516nm

Concentration: 10 mg/mL

Ingredients: Polystyrene, Ultra Pure Water, FITC Derivatives


Product Features

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

Fluorescence characteristics: Contains highly fluorescent dyes that are embedded inside the microspheres, effectively preventing fluorescence quenching.

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.

Optical performance: The fluorescence emission of fluorescent microspheres is stable and not affected by changes in external environmental media.


Application Fields

 

Biomedical research: Fluorescent polystyrene microspheres can be used for cell labeling, imaging, and as carriers 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.

High throughput drug screening: As a signal carrier, it helps to quickly screen a large number of compounds and search for potential drug candidates.

Medical diagnosis: In areas such as immune analysis and detection, the surface of microspheres retains their original functional groups, which will not affect immune analysis and detection.

Tracer research: In fields such as phagocytosis research and pore size determination, fluorescent microspheres can be used as tracers to monitor cellular endocytosis processes.

Comfortable and Easy to Wear Daily
Size: 2 Little Kid, Color: Navy/Blue
My daughter has been wearing these navy/blue shoes since the weather has been less rainy and more sunny. They are great for outdoor play, especially on days when it's warm outside. The knit mesh upper keeps her feet from overheating, and the cushioned insole feels supportive without being stiff. At size 2, the fit is accurate and the width runs a bit roomy, which gave her some growing room without feeling loose. The slip-on design with elastic laces and pull tabs is a real plus. She can get them on and off without any help, which she loves. The shoes are light enough that she barely notices them during long active days. My one small complaint is that the sole feels more like firm foam than rubber, so they can be a little slippery on smooth indoor floors. For the price, these deliver solid everyday value. They look good, hold up well to regular use, and my daughter reaches for them first most mornings. Pros: - Breathable mesh keeps feet cool - Easy slip-on design with elastic laces and pull tabs - Lightweight and comfortable for all-day wear - Accurate sizing with a roomy width - Durable for the price Cons: - Sole can be slippery on hard smooth surfaces - Limited outsole grip compared to rubber-soled shoes

Great kids' shoe — easy on, comfy all day
Size: 3 Little Kid, Color: Pink/Lavender
My kid has been wearing these for a few weeks now and I'm genuinely impressed with how well they've held up. The knit mesh upper keeps feet cool and comfortable during long days at school and outdoor play, and the cushioned EVA midsole does a great job absorbing impact. What really won me over is the slip-on design with elasticated laces and dual pull tabs — my child can put them on and take them off completely independently, which is a huge win. The fit is snug but not tight, and they run a bit roomy in width, which is great for kids with wider feet or those who need a little growing room. At $32, the quality feels solid for the price. Lightweight, breathable, and easy to wear — these check all the boxes for an everyday kids' shoe.

Cute, Comfortable, Light-Weight Shoes, Perfect for School
Size: 11 Little Kid, Color: Pink/Lavender, Size: 11 Little Kid, Color: Pink/Lavender
These have turned out to be great everyday shoes for my 5 year old. She normally wears a size 10, but since that size wasn’t available, I ordered the 11 expecting her to grow into them. I was pleasantly surprised that they already fit her pretty well. There’s still a little extra room in the toe area, but the shoes fit securely around her ankles so they don’t feel loose or slip off while walking or playing. She says they’re very comfortable and loves how easy they are to slip on by herself. The lightweight design is nice for everyday wear, and they’ve held up well so far despite being worn almost daily. They've become her favorite shoes to wear! Also the pink/lavender color is really pretty in person. Overall, I’m very happy with them and would order again.

Great shoe well made
Size: 13 Little Kid, Color: Pink/Lavender, Size: 13 Little Kid, Color: Pink/Lavender
Really good shoes at a fair price. My daughter loves the pink and purple gradient colors. Really beautiful. Shoes have proven themselves very durable. She's been wearing these a few times a week for the last couple months and they still look new aside from some dirt stains. Fit perfectly. Very comfortable. This is always her first pick in the morning when she's getting dressed. Good breathability you can wear these in hot summer weather without sweaty feet. Versatile shoe looks good enough to wear out and about or exercise in.
