Product Name

Name:PEI stabilized gold nanoclusters

Product Overview

Polyethylene imine stabilized gold nanoclusters (PEI Au NCs) are a type of nanomaterial that combines gold nanoclusters with polyethyleneimine, consisting of several to dozens of gold atoms that form the core of the gold nanoclusters. Polyethylene imine (PEI) is a positively charged hyperbranched polyamine selected as a capping agent that wraps around the surface of the gold nanoclusters. PEI Au NCs have been widely used due to their high luminescence properties and stability over a wide pH range. PEI Au NCs have good biocompatibility, easy surface modification or functionalization, making them more attractive in many biomedical applications.

Technical Parameter

Concentration:0.1 mg/mL

Solvent:Water

Diameter:1-5 nm(HRTEM:/span>

Diameter:Brown solution

Product Features

1) Optical properties: PEI Au NCs have fluorescence properties that depend on their own size, which makes them widely applicable in fields such as biological imaging and fluorescent probes.

2) Stability: Due to the encapsulation effect of PEI, PEI Au NCs exhibit high stability in physiological environments and are not prone to aggregation or degradation.

3) Positivity: Polyethyleneimine is a positively charged hyperbranched polyamine that exists on the surface of gold nanoclusters, making PEI Au NCs easy to bind with negatively charged materials.

Application Fields

1) Biological imaging: PEI AuNCs, as fluorescent nanomaterials, can be used for cell imaging, tissue imaging, and tumor imaging.

2) Drug delivery: PEI AuNCs can also serve as drug delivery systems due to their easily modifiable nature.

3) Chemical testing: PEI AuNCs have sensitive detection capabilities for certain chemical substances, making them suitable for fields such as environmental monitoring, food safety, and biomarker detection.

3 in 1 Deal: Moisturizer, Sunscreen, and No White Cast!!

Short Review: It’s affordable and dark-skin friendly! A rich moisturizing lotion texture, lightly fragranced, with no white cast. If you have oily skin, you don't even need to moisturize beforehand, just skip straight to this sunscreen after cleansing. (Probably wouldn't be the same for people with dry skin). It’s at first tacky but it dries down to a smooth finish. Though this does have a shine to it that leaves your skin with a healthy dewy glow, if you have super oily skin like me, do follow up with a powder. If not after a couple of hours you’ll go from glowy to a grease soaked donut. The Story: I was shocked that the bottle was tiny/the size of my hand (funny when I’ve been through this shock at least a hundred times when trying sunscreens from Korean and Japanese brands) but rest assured, it does do its job (at least for me) and is affordable. I’ve struggled with finding a decent sunscreen for a good year now. I’ve tried Neutrogena Clear Face (baaad breakout), Biore Aqua Rich (breakout), Nieva UV Super Water Gel (breakout), Frudiva (okay no breakouts but heavily scented, thick lotion, and left me super shiny), Hada Labo (beautiful lightweight texture but made me break out)—basically the struggle was real. Until I landed on Australian Gold tinted sunscreen. That stuff is magic, keeps me matte, and makes my skin look better but the darkest shade has a gray undertone so I have to follow it up with bronzer. This sunscreen is perfect for when I don’t want to deal with the hassle of wearing my tinted sunscreen, am going out to run a quick errand, or when I’m staying indoors the entire day. The pump is super useful, especially if you do the two finger method application method. It comes out a yellowish color but once you rub it in, it easily disappears into the skin. At first, it feels tacky, almost as if you’ve applied a serum, but within 1-3 minutes it dries down to a smooth finish. It does leave a shine but nothing that a sebum or setting powder can’t handle for 4-5 hours. The big pointer is that so far no breakouts but I’ve been using this only for two days so I’ll update this if I see any changes in my skin. I’m super glad I found this affordable option! I was looking at Elta MD (heard it piles, especially with makeup so I held back) and La Roche Posay Anthelios Ultra Light but luckily I decided to peak at the more affordable spectrum of sunscreen. As of now, this sunscreen is a keeper. Let’s see how it stands after a week!
