The 3D tunable orientation of an AgNW by photoalignment and an electric field could provide a new way to assemble large colloidal nanomaterials and fabricate functional E-O devices.Įlectric−optic devices liquid crystal order parameter photoalignment self-assembly silver nanowires. The colloidal dispersions of AgNWs in the LC cell influenced the ion transfer, elastic constant, dielectric anisotropy, and near LC alignment, changing the E-O properties of the LC devices. The AgNW orientation is tuned with an electric field, through the rotation of an LC director n, which allows three-dimensional (3D) tunable orientation combined with photoalignment. The AgNWs are precisely self-assembled via photomasks with twisted nematic and planar alignment models in microdomain regions. Here, we demonstrate a large-scale, simple, multi-microdomain, and noncontact photoalignment technology to align colloidal silver nanowires (AgNWs, length ∼4.5 μm, diameter ∼70.6 nm) in a liquid crystal (LC) with a high two-dimensional order parameter (about 0.9). We rate them False.The dispersion and tunable alignment of colloidal nanomaterials is desirable for practical applications in electric-optic (E-O) devices however, it remains challenging for large one-dimensional nanomaterials with a large aspect ratio. Silver HOLISTICS Colloidal Silver Liquid Bundle Includes Colloidal Silver Spray (4 OZ) & Refill Solution (16 OZ) with Free Dropper - Immune Support Supplement for Children, Adults, & Pets 4. Snopes declared that statement false.Ĭlaims that colloidal silver can’t turn you blue are also wrong. Karason got the nickname "Papa Smurf" because of his skin’s blue tint, and earlier this year Snopes looked at claims that publicity surrounding his skin turning blue from colloidal silver was disinformation to scare people away from using it. Although argyria doesn’t typically cause major health problems, the clinic said, "it can be a cosmetic concern because it does not go away when you stop taking silver products." It can build up in the body’s tissues over months or years. The Mayo Clinic has said that it’s unclear how much colloidal silver people can take before it harms them. The condition is caused by silver building up in the body’s tissue and, according to the center, people have developed it from using both homemade and commercial colloidal silver products. The most common: argyria, which is usually permanent. What’s not true, according to health experts, is that it’s impossible for colloidal silver to turn you blue.Īs we’ve previously reported, colloidal silver can imperil health and cause serious side effects, according to the National Center for Complementary and Integrative Health. It’s true that Karason bought a device to make his own colloidal silver at home, Wired reported in 2017. (Read more about our partnership with Meta, which owns Facebook and Instagram.) The Instagram post was flagged as part of Facebook’s efforts to combat false news and misinformation on its News Feed. This clown made a home brew concoction that wasn’t silver." How much Daily Immune Booster Liquid is too much Even at the full dosage of drinking 555 litres, if a person notices any sign of argyria (a slight blue tint to. "It’s impossible for pure colloidal silver to turn you blue," the post says. He developed argyria, a discoloration of the skin caused by excess silver ions in the body.īut a recent Instagram post sharing the picture of Karason suggests a scam is afoot. Karason, who died in 2013, said that his skin started turning blue after treating it with silver and, for more than a decade, drinking colloidal silver, a concoction of tiny silver particles in liquid that’s sometimes promoted as a dietary supplement. All of his skin is blue, and in 2008, when this photo was taken, he was appearing on NBC’s "Today" show to talk about what happened to him after taking colloidal silver. In a photo from 2008, Paul Karason peers at the camera over glasses perched on his blue nose.
