Product Name

 AIE Carboxyl modified  red fluorescent polystyrene microspheres

 Product Overview

AIE molecules usually do not fluoresce or fluoresce weakly in solution, but emit strong fluorescence in the aggregated state. By encapsulating AIE molecules in polystyrene microspheres or polymers, their fluorescence efficiency can be increased and the effect of the external environment on the AIE molecules can be reduced. This restricts the movement of the AIE molecules and reduces the non-radiative leaps, thus increasing the fluorescence intensity. The encapsulation of microspheres can protect AIE molecules from external factors and improve their stability. At the same time, various functional groups can be introduced on the surface of the wrapped material, such as carboxyl groups for coupling antibodies.

Product Features

 

1. Strong fluorescence emission: it can show strong fluorescence in the aggregated state, which overcomes the problem of fluorescence burst when traditional fluorescent materials are aggregated. 

2. Good light stability: It is not easy to photobleach, and can maintain stable fluorescence performance under prolonged illumination, which is suitable for long-term monitoring and imaging. 

3. Low background interference: in the organism, due to its unique luminescence mechanism, it can effectively reduce the background fluorescence interference of the biological tissues themselves and improve the clarity and accuracy of imaging. 

4. Easy functional modification: various functional groups can be introduced through chemical modification to achieve specific functions such as target recognition and drug loading to meet different biomedical applications. 

5. Good biocompatibility: After appropriate surface modification, it can reduce the biotoxicity and improve the safety and applicability in the organism.

Application Fields

 

1. Bio-imaging: AIE materials can be used for cell imaging, tissue imaging and in vivo imaging. For example, AIE nanoparticles can specifically target cancer cells or organelles for early diagnosis of tumours and treatment monitoring. 

2. Biological detection: AIE materials can be used as fluorescent probes for the detection of biological molecules, such as proteins, nucleic acids and pathogens. Through specific binding with target molecules, the fluorescence signal of AIE materials will change, thus achieving the detection and quantitative analysis of target molecules. 

3. Drug delivery: AIE materials can be used to construct drug delivery systems to achieve targeted delivery and controlled release of drugs. For example, AIE nanoparticles can be loaded with drug molecules, and through surface modification to achieve targeted recognition and internalisation of tumour cells, improving the therapeutic effect of drugs. 

4. Photodynamic therapy: AIE materials can generate reactive oxygen species, such as monoclinic oxygen, under light to kill cancer cells or pathogens, and AIE materials can be used as photosensitizers for photodynamic therapy to achieve non-invasive treatment of tumours. 

5. Gene therapy: AIE materials can be used for gene delivery and gene expression regulation. For example, AIE nanoparticles can be loaded with gene molecules, and through surface modification to achieve targeted recognition and internalisation of cells, improving the efficiency of gene therapy.

Light, Moisturizing, and Smells Great, Totally Worth It
Style: Sunscreen Lotion 70 SPF, Size: 6.7 Fl Oz (Pack of 1)
I’ve been loving this Neutrogena Beach Defense sunscreen. It goes on so smoothly and feels more like a light body lotion than a typical sunscreen, which I really appreciate. It’s super easy to apply and doesn’t leave that sticky or greasy feeling that a lot of other sunscreens do. My skin actually feels hydrated after I use it, which is a nice bonus especially when I’m out in the sun all day. The scent is fresh and beachy, not overpowering or too “sunscreen-y,” and it fades nicely after a while. It also absorbs quickly and doesn’t leave a white cast, which makes it great for reapplying throughout the day. I’ve used it at the pool, the beach, and just for everyday sun protection, and it’s held up really well every time. It’s a little pricier than some drugstore sunscreens, but honestly, the quality makes it worth it. It feels good on my skin, protects well, and doesn’t make me feel gross after hours in the sun. I’ll definitely be picking up another bottle when this one runs out.

Protected Our Skin and Smells Good
Size: 6 Ounce (Pack of 1)
I love this stuff! My husband and I bought it as a last minute grab for our honeymoon and it was well worth it! I'm very sensitive to the sun AND to sunscreens, so I needed something with simple ingredients that would also protect my skin without breaking me out. This not only kept away the burning rash I get from the sun, but protected my husband and I from any sunburn at all. It worked not only in dry conditions, but it stayed on for hours after we swam in the ocean. We also liked the fact that it smelled herbal, almost like pizza/Italian seasoning. That didn't bother us because we both hate the smell of most sunscreens. If you have sensitive skin or are looking for a more natural product, I highly recommend this!

Great reef-safe, easy-to-apply sunscreen (comparison of three ThinkSport products)
Size: 6 Ounce (Pack of 1)
I will start by saying that I am used to traditional non-mineral sunscreens and tend to only buy physical/mineral-based sunscreens when I'm going to be in a tropical ocean and need something reef-safe, though more and more kids sunscreens are shifting to mineral-based. After quite a bit of research I settled on ThinkSport for my family's recent trip to Hawaii, and I'm very pleased with it. I brought and used three types of Thinksport sunscreen: Thinksport Kids lotion (yellow/orange and teal squeeze bottle), Thinksport adult lotion (Black, white, and orange squeeze bottle), and Thinksport adult spray (black, white and orange spray bottle). All protected us from sunburn and rubbed in to be invisible as long as skin was dry and free of visible hair (visible whiteness persisted around my husbands facial stubble and chest hair). The only difference between the kids lotion versus the adult lotion is scent--the kids version has a fruitier, more tropical but not-too-strong scent (possibly coconut and something else? it was hard to identify) that I found unobjectionable (though one if my kids wasn't a fan), and the adult lotion had a lighter, less sweet, more citrus-y scent (my son though maybe lime and mint, but I'm not sure that's accurate) that I LOVE. The adult spray had no discernible scent, so I suspect the kids spray might be fairly unscented as well. The easiest to apply by far was the spray--it sprays on white, but feels very light, rubs in easily, and becomes invisible quickly. I was a little worried about whether it could possibly be effective given how light and thin it felt, but it was! The lotions weren't thick for a lotion (but much thicker than the spray) and went on easily, but took more rubbing in to disappear than the spray (this is consistent with my experience with lotion vs spray in traditional sunscreens as well). Invisibility was harder to get after a second or third application or when skin was damp, but all-in-all I found all three Thinksport products to be superior to other mineral-based sunscreens I have tried in the past. In the future I'll probably buy the adult thinksport spray for my kids and husband (who all much prefer a spray-on sunscreen) and the adult thinksport lotion for myself (because I love the scent and don't mind rubbing it in).

Dependable sun protection for active days outdoors
Size: 6 Ounce (Pack of 1)
I like how this sunscreen provides reliable broad-spectrum protection and holds up well during outdoor activities. The zinc oxide formula gives me peace of mind, and I appreciate that it's water resistant and reef-safe. It applies smoothly for a mineral sunscreen and stays on effectively during sports, swimming, and long days in the sun. Overall, it's a trustworthy option for anyone looking for strong sun protection.

Clean product
Size: 3 Ounce (Pack of 1)
I only gave it 4 stars because of the smell. Of course it’s sunscreen so it’s going to have a chemical smell but this smell is just too strong for me. Other then that, it’s a great sunscreen. Does take some more rubbing in and be carful to rub it in really good or you’ll have white streaks all over your face. Leaves a bit of a white cast. You don’t need much.
