Product Name

Name: Gold Nanobipyramids

Product Overview

Gold nanobipyramids are nanostructures of precious metal gold with unique geometric shapes and surface plasmon resonance properties. They usually consist of double hexagonal pyramids with a common base, exhibit anisotropy, and can exhibit significant longitudinal surface plasmon resonance properties in the visible to infrared spectrum. These properties of gold nanobipyramids make them potentially useful in fields such as optical sensing, surface-enhanced Raman scattering (SERS), and photothermal conversion therapy.

Technical Parameter

Appearance:Tea-colored dispersion

Length:0-85 nm

Diameter:0-35nm

Product Features

Surface plasmon resonance (SPR): Due to its size and shape, gold nanobipyramids exhibit strong surface plasmon resonance effects, especially with significant resonance absorption peaks in the longitudinal direction (along the long axis of the bipyramids).

Polarization dependence: The SPR effect of gold nanobipyramids shows obvious polarization dependence, that is, their optical properties change according to the polarization direction of the incident light.

High local field enhancement: The tip and edge regions of gold nanobipyramids can produce high local electromagnetic field enhancement, which is very important for applications such as surface-enhanced Raman scattering (SERS) and photocatalysis.

Biocompatibility: Gold nanobipyramids generally have good biocompatibility, making them suitable for biomedical applications such as drug delivery, biosensing, and photothermal therapy.

Application Fields

Surface Enhanced Raman Scattering (SERS):Gold nanobipyramids have important applications in the preparation of SERS detection substrates due to their surface plasmon resonance properties.

Biosensing and photothermal therapy:The surface plasmon resonance characteristics of gold nanobipyramids are significantly better than those of gold nanorods of corresponding sizes, so they have broad potential applications in biosensing, photothermal therapy, and in vivo SERS detection.

Not for super chewers!
Color: Four colors, Size: 5cm (with rope), Color: Four colors, Size: 5cm (with rope)
These rope ball toys arrived today. My poodle puppy loves rope ball toys and playing tug of war. These didn’t last 10 minutes. For context, she is 1 y.o., 30 lbs., is not teething & has her adult teeth. She did this on her own- we were not playing tug of war at the time the toy fell apart. At least there are 3 more in the package & when the rope is done, we’ll still have the balls to play with.

Good and comfortable toe socks
Size: 10-12, Color: Black 5 Pairs
First time wearing toe socks. I bought them to help prevent athlete's foot between the toes, which I'm prone to getting. Being a guy, I did have some reservations because I thought they'd look silly or whatever but I went ahead and bought these since they're going inside shoes anyway. I'm so glad I did! My only complaint is that the length of the toes are a bit short. In shoes I wear a men's 11 and I ordered 10-12 in these socks. The overall length is perfect but the toes are a bit too short and won't go all the way back to my webbing in the 1st and 2nd interspaces. The other toes and interspaces are fine. It's a minor complaint and not enough to remove a star. Overall I'm very satisfied with the product. I've suffered from Morton's Neuroma in both feet and various interspaces all of my life. I think I've finally found the solution. I've been walking 4.4 miles a day for over a month now. Something I've never been able to do. I wear these ZAKASA toe socks, along with the Dr. Wolf orthotics which have good arch support and a metatarsal arch just behind the metatarsal heads. I also wear the Bronax shoes which have a wide forefoot to let the toes spread out. The combination of the shoes, socks, and orthotics has worked wonders on my feet! No athlete's foot either! I highly recommend these ZAKASA toe socks. I've bought two 5 packs already. No regrets!

Great quality and price per pair
Size: 10-12, Color: White 5 Pairs
Had these about 6 weeks now and am very pleased with how they've held up so far. I've gone through 2 other brands before this and will be sticking with them as long as they continue to hold up. Seams are still good, toe hasn't worn through at the toenail, no visible fading/wear on the pads of the feet. They are still annoying to straighten out after washing like all other toed socks, but the fit has held up and elastic is still snug and comfortable after daily wear (I did buy 2 packages, so they do get rotation before being worn)

Good for wearing with Vibram Fivefinger shoes
Size: 8-10, Color: Black 5 Pairs
They are good, comfy socks that fit well on a size 43 eu (9.5-10 US) foot in medium. Be aware that these are the same socks that you get when you order Caidenieu toe socks and dozens of other listings as well. So just buy the cheapest ones you can get. They come in the same bag with the same cards and everything. I wear them with my vibram fivefinger shoes very comfortably.
