Study Shows Silver Nanoparticles Attach to HIV-1 virus

Study Shows Silver Nanoparticles Attach to HIV-1 virus October 14, 2005 feature In the first-ever study of metal nanoparticles' interaction with HIV-1, silver nanoparticles of sizes 1-10nm attached to HIV-1 and prevented the virus from bonding to host cells. The study, published in the Journal of Nanotechnology, was a joint project between the University of Texas, Austin and Mexico Univeristy, Nuevo Leon. "Our article opens an important avenue for research," said Miguel Jose Yacaman, from University of Texas, Department of Engineering and one of the study's authors. In this study, scientists mixed silver nanoparticles with three different capping agents: foamy carbon, poly (PVP), and bovine serum albumin (BSA)."Not using a capping agent could result in the synthesis of big crystals instead of nanocrystals," explained Yacaman. Transmission electron microscopy (TEM) showed the silver nanoparticles in the foamy carbon matrix were joined together, but an ultrasonic bath in deionized water released a significant number of nanoparticles. These nanoparticles were of size 16.19 (+-8.69)nm and had the greatest variety of shapes, such as icosahedral, decahedral, and elongated. "Because of the synthesis procedure, the foamy carbon-coated naoparticles are more likely to have broad shape distribution," said Yacaman. Scientists used the electron beam to release the remainder of the nanoparticles from the joined bundle. For the PVP-coated silver nanoparticles, scientists used glycerine as a dissolving agent. These particles were of size 6.53 (+-2.41). In the third preparation, scientists used serum albumin, the most common protein in blood plasma. The sulfur, oxygen, and nitrogen chemicals in BSA stabilized the nanoparticles, which were in the range of 3.12 (+-2.00) nm. Scientists studied the absorption spectra of the different preparations to pinpoint their shapes. "Spherical nanoparticles absorbed in the blue region of the spectrum, for example," Yacaman said. Also, the UV-Visible spectra graphs helped the group determine nanoparticle sizes. "The surface plasmon resonance peak wavelength increased with size," explained Yacaman. Scientists tested, in vitro, each of three silver nanoparticle-preparations in HIV-1 cells. Yacaman and his colleagues incubated the samples at 37 C. After three hours and 24 hours, respectively, 0% of the cells were living. The results showed that a silver nanoparticle concentration greater than 25 ug/mL worked more effectively at inhibiting HIV-1 cells. Plus, the foamy carbon was a slightly-better capping agent because of its free surface area. Size also played a role since none of the attached nanoparticles were greater than 10nm. Scientists think the nanoparticles bonded through the gp120 glycoprotein knobs on HIV-1, using the sulfur residues on the knobs. The spacing between the knobs of ~22nm matched the center-to-center nanoparticle spacing. Although this study shows silver nanoparticles may treat HIV-1, scientists need to research this relationship further. "We lack information regarding the long-term effects of metal nanoparticles," cautioned Yacaman. Scientists are forming a preventive cream for HIV-1, which they will test on humans. Scientists are also studying other uses for silver nanoparticles. "We're testing against other viruses and the 'super bug (Methicillin resistant staphylococcus aureus).' Our preliminary results indicate that silver nanoparticles can effectively attack other micro-organisms," Yacaman said. By Syeda Z. Hamdani; Copyright 2005 PhysOrg.com

Thanks, Serpo.
I like scientific nano-articles. This is a dandy. :) And I heard somewhere today (CNBC?) that there was a new HIV prevention vaccine released today. THAT vaccine part made me grown. I applaud the silver research angle on this terrible disease which has taken so many lives over the last 3 decades.

But does AIDS exist?

How do you make nano particles? Making (colloidal which is not really colloidal) silver breaks silver electronically but I am sure not to the point of 'nano'

[palani]

Ionic silver is not colloidal but is easy to make. To make colloidal I would suggest something like a TIG welder with silver plate and silver electrode ... capture the smoke ... it'll probably be as close to nano as you can get.

But does AIDS exist?


It exists enough to make a lot of money off of it.

Thank you! Exactly what I was looking for.

Careful with anything "nano" that goes inside your body.

True story.

There are some nano-carbons out there. I've ran into one from Russia. Long story short, it was an element that apparently could do anything , not short of filtering everything from water. This form of nano carbon IS used by firefighters for water adsorption, and it does adsorb lots of contaminants, way more than regular carbon. Naturally, it was tried for drinking water filtration. Russians use simple method to test for water safety after filtration, they put crawfish into a tank with water. Guess what, crawfish died in nano-carbon filtered water, nobody knows why. Scientific explanation is something in the nature of nano particles being able to go right through body cells.

Eeeeek

Interesting stuff. What's the story with this.

Smallest Silver Nanoparticles

Highest Particle Surface Area
Maximum Effectiveness


That is interesting, the smallest particles with the largest surface area.

Sounds as if you might be able to at least teleport with that stuff, if not time travel.

[Horn]

Typically I'm a Silver guy, except when drinking, or snorting.

Go for the Gold.

There is a patent for the cure for AIDS. It belongs to Marvin Antelman, who patented it on October 14, 1997. It's Tetrasilver Tetroxide. You can read the patent for yourself here:

http://patft.uspto.gov/netacgi/nph-Parser?Sect1=PTO1&Sect2=HITOFF&d=PALL&p=1&u=%2Fnetahtml%2FPTO%2Fsrchnum.htm&r=1&f=G&l=50&s1=5676977.PN.&OS=PN/5676977&RS=PN/5676977

I'm not sure this is widely known. I've posted this here once before, but nobody picked up on it.

I think I understand why the patented AIDS cure is not widely known.

As Osoab has duly noted regarding whether AIDS exists:


It exists enough to make a lot of money off of it.

Having a cure for it would negate this 'principle'.

This falls into the same general dynamic that kept some of Tesla's inventions from ever being implemented commercially, such as the 'wireless transmission of electricity', of which J.P. Morgan asked 'How would you meter it?' To which there was no 'good' answer, so Morgan stopped funding this Tesla project.

This insight came to me while watching the MSM nightly news yesterday in which there was a story about all the drugs now being used to 'treat' AIDS. Not a word about a cure for AIDS. As long as the treatment is profitable, we will never see a cure for this man-made disease. I don't have a link for it, but I read somewhere that AIDS was made in a laboratory, and spread in vaccines distributed in Africa to depopulate that continent. Here is a video of Boyd Graves, a researcher of AIDS, talking about the cure:
