Re: [DIYbio] A Philosopher's Stone

hei my dear alchemists...

i have been posting this already a few times....

http://scholar.google.com/scholar?q=biosynthesis+of+nanoparticles

there is loooaods of that stuff out there, using fungi, bacteria and even plants. no need for gm bacteria for doing so -> genspace. 

and even worms can shit out nanoparticles:

http://www.nature.com/nnano/journal/v8/n1/full/nnano.2012.232.html

and the news in http://www.rawstory.com/ , although it's cool, it's not that much of a new invention.

and finally, talking about the philosopher's stone... u need gold to make gold. and of course the prize of gold - chloride solution is much more expensive than pure gold. people would have figured it out. and if you have a gold-ionic solution... you can also just put a battery to it and get the metallic gold.

we did some experiments at NanoSmano to use fusiarum solani to make silver nanoparticles (silver is cheaper to try out things....) and using fungi is cool, easy to culture and breed. detecting silver nanoparticles is also straight forward.... the solution / suspension turns blue, due to the quantum effect of small silver particles. got a nice absorbtion band which is possble to be detected with some led's and phototransistors.
