Using Cinnamon In the Production of Nanoparticles

An anonymous reader writes "Scientists at the University of Missouri used cinnamon to replace almost all toxic chemicals needed for making gold nanoparticles used in electronics and healthcare products. Nanoparticle production requires the use of extremely dangerous and toxic chemicals. While the nanotechnology industry is expected to produce large quantities of useful nanoparticles in the near future, the entire production process could be detrimental to the environment."

      The two come from the same genus and are extremely similar. This is why cassia can be sold as low-grade "cinnamon" - it is nearly identical to the Sri Lanka variety.

      For manufacturing purposes I doubt there is any significant difference.

      Here's a map with the top world producers of Cinnamon in 2005. China has 10 yellow bubbles (=10% of the world's top producer) meaning in 2005 it produced 60,000 tones of cinnamon.

      For comparison, the entire world's gold production of 2006 was 2,310 tons.

      Me thinks that the world risks running out of gold faster than China of cinnamon... but hey, I might be mistaken.

      However, on another track, TFA says:

      They mixed gold salts with a common spice – cinnamon – and stirred the mixture in water to synthesize gold nanoparticles.

      Now, unless one finds a method to obtain gold salts by using plain cooking salt (Ok... I'll make a concession and allow capsicum powder as well), this step may require indeed the use of toxic chemicals.

  10. The "toxicity" part is bullshit... by MagusSlurpy · · Score: 5, Informative

    The actual article talks about how gold nanoparticles are often made with super-strong reducing agents like sodium borohydride and how this is awesomely bad for the environment.

    What the article doesn't mention is who made the very first gold nanoparticles, or how they were made.

    It was Michael Faraday (yes, that Faraday), who made them using a reducing agent called. . . phosphorus. Horribly toxic, world-destroying . . . Oh, wait, it's safe. Never mind.

    There are 80 thousand ways to make AuNPs, the reason the strong reducing agents are usually used is because it's simply a quicker reaction, or because you want them there to activate something else you are sticking to the surface of the nanoparticle.

    Now, the part about the cinnamon extracts stabilizing the AuNPs in physiological conditions, that might be more impressive - I'm not familiar with work in that area. But the toxicity part is nothing more than a cry for attention.

      Nice; but nowadays the toxic hydrazine and sodium borohydride are used. Then how do you come to say 'the "toxicity" part is bullshit' in your topic?

      That said, phosphorus itself is not completely harm-free itself ...

      They are only sometimes used. There are lots of current (last five years) papers where they aren't used, NaBH4 and N2H4 are just extreme examples being used - phosphorus is still used, as is sodium ascorbate (also known as vitamin C). Hell, the lab down the hall from mine makes AuNPs via laser ablation and deposition - no reducing agent needed at all, just a vacuum.

      Phosphorus is only dangerous if you eat it on the multi-gram scale or if you heat it, and frankly, anyone who does that gets what they deserve. If you're worried about waste, elemental phosphorus will oxidize pretty quickly with contact with air (and gold nanoparticles) and become biocompatible phosphates.

      Yes, white phosphorus is pyrophoric, but it's the less stable of the two allotropes, and it's pretty hard to make, so you don't need to worry about it being a sideproduct.
