Product Overview

 

Polydopamine nanoparticles (PDA NPs) are nanoscale materials formed by the self polymerization of dopamine monomers under specific conditions. Its structural characteristics lie in its polyphenolic structure, with a surface rich in functional groups such as amino and phenolic hydroxyl groups, which provide abundant chemical modification sites for it.


Technical Parameter

Diameter:140-250nmãâ‚?00-450nm(TEM:/span>

Appearance:Black powder

 

Product Features

Good biocompatibility: Due to its unique adhesion and biodegradability, PDA nanoparticles can enter a large number of types of cells and exhibit good biocompatibility in biomedical applications.

Excellent photothermal conversion efficiency: PDA nanoparticles have strong absorption in the near-infrared region, which can quickly convert light energy into heat energy for photothermal therapy.

Powerful antioxidant capacity: Some PDA nanoparticles themselves have the function of eliminating reactive oxygen species (ROS) and reducing oxidative stress levels, playing a unique advantage in the treatment of periodontitis.

Efficient drug delivery: Due to its good adhesion and biocompatibility, PDA nanoparticles are widely used as drug carriers, which can effectively encapsulate and deliver drugs.

Antibacterial performance: Combined with antimicrobial peptides (AMP), PDA nanoparticles can be designed as stimulus responsive antibacterial platforms for antibacterial therapy.


Application Fields

 

 

Neuroprotection and Remote Neuronal Stimulation: As an organic and biodegradable multitasking tool, PDA nanoparticles have significant applications in neuroprotection and remote neuronal stimulation.

Periodontal disease treatment: The antioxidant properties of PDA nanoparticles in periodontal disease make them an effective treatment option.

Tumor treatment: PDA nanoparticles can be used as delivery carriers for chemotherapy drugs and immune agonists, enhancing anti-tumor immune responses. In addition, they can also be used for photothermal therapy to rapidly kill cancer cells.

Antibacterial therapy: A multifunctional and stimulus responsive antibacterial platform was constructed by combining PDA nanoparticles with antimicrobial peptides for antibacterial therapy.

Rheumatoid arthritis treatment: PDA nanoparticles can effectively treat rheumatoid arthritis by inhibiting the STING pathway.

Review for: Cooling Gel Wrist Rest Pad -Full Size 18"- Memory Foam Palm Rest with Non-Slip Footpad - Ergonomic Design Wrist Support - Desk Keyboard Accessory Gaming Gear (Large-Full Size). I've had this for a week and I'm impressed! There is no skimping on quality, which is rare nowadays. It is made extremely well, solid yet soft. I love the feel of the outer cover. It's comfortable and stays in place. And let me add... I'm putting it to the test. I have a rolling over-bed/couch desk. It has a raised 1/4" lip around the top. I put this wrist-rest on top of that lip. So far there's not any wear across the bottom of this wrist-rest. And that's with me using it for my wrists... and my elbows. It far surpasses the last rest I bought. From my experience, many sellers slap the phrase "memory foam" on their products when they are not. That's NOT the case here. This rest immediately bounces back to its original shape. It's true memory foam! It's so comfortable that I forget it's there yet I enjoy the comfort immensely. Also, it has no smell. ***From my experience so far... I highly recommend this product!

Comfortable and functional, but beware of cardboard/mdf insert
Size: Compact
I’ve been using this wrist rest for a bit now, and for the most part, it does exactly what it’s supposed to do. It provides a comfortable amount of support for my wrists during long typing sessions, and the cooling gel aspect is definitely a nice touch that adds to the overall comfort. That said, there are a couple of drawbacks to keep in mind. The surface seems to attract dirt and grime pretty quickly, so you’ll need to wipe it down often to keep it looking clean. More importantly, the build quality of the base is disappointing. I believe its a cardboard inserted into the bottom, which snapped very easily when I was just barely bending it while cleaning it. It’s a shame because the rest of the product is great, but I really wish they had used a more rigid, durable material for the bottom instead of whatever this cardboard/mdf is. This is why I’m giving it 4 stars.

I love it!
Size: TKL- Tenkeyless, Size: TKL- Tenkeyless
This wrist pad is the right size, approx. 14” wide. It provides support and doesn’t hurt my wrist. I needed a wrist rest that was comfortable and this one is awesome. It’s has some firmness, but it’s not hard, and has some give to it, see video. I also like the fabric, it feels good against your skin and doesn’t collect lint. The plastic gel pads always seem too hard for me, not providing comfort. Glad to find this wrist pad on Amazon! It fits well next to a laptop or large iPad (especially if you have the keyboard to go with the iPad). The wrist pad allows me to work in comfort. With my laptop, I use this wrist pad along with a soft mousepad, on the right side of my laptop.

Great!
Size: Compact
Super soft and very comfortable! It perfectly fits my 75% keyboard. It was almost impossible to find one at this size and I'm glad I did. There's no "overhang" at all and its flush with my keyboard. It stays put and isn't slippery at all and it's just the right height too.
