Re: What are microspheres and coacervates?

Microspheres and coacervates are possible contenders for the basis of the first primitive cells. In this context, a microsphere is made by amino acids joining under heat to form short peptide chains. When the water, in which ...

What are microspheres and coacervates?

... I know that living cells were probably preceded by protobionts, which had an internal chemistry differnt from the external chemistry. Now what are microspheres and coacervates? Are they some form of early membranes? How are they related, how do they differ and what is their role in protobionts? ...

Important unknown nanotech within humans

... colloidal process, We propose a novel technique to fabricate a free-standing three-dimensional colloidal crystal by self-assembling the colloidal microspheres with controllable thickness from the air–liquid interface. Highly ordered three-dimensional colloidal crystals are formed by polymethylmethacrylate ...
