The here is to perform atomically precise 
[[piezochemical mechanosynthesis]] in solution before going to a full on [[PPV]] vacuum, 
because this is likely an easier task. Walking before running.

== Relation to R&D in bio-mineralization ==

Current mainstream bio-mineralization research may not be very 
aligned with a focused aim at advancement of [[APM]] towards [[gemstone metamaterial technology]].

This is out of two reasons:
* A lack of a focus on atomic precision.
* A focus on soon reachable better material properties rather than fundamentals for only later reachable advanced material properties. More concretely: – a focus on materialtype-heterogeneous metamaterials without atomic precision rather than – a focus on materialtype-homogeneous metamaterials with atomic precision.

One major focus of bio-mineralization R&D is the 
recreation of composite materials with good mechanical properties like e.g. nacre 
without a focus on atomically precise material synthesis one moiety at a time.

=== Lack of a focus on atomic precision ===

In bio-mineralization proteins may release salt-ions in close vicinity of 
the deposition target. Thereby creating a local supersaturation and a falling out of the salt ions 
onto the bio-mineral traget-structure. But all that without full atomic precision. 
{{todo|To investigate in how far this is really the case, and in how far it is even known how much or less of atomic precision is involved in natural bio-mineralization.}}

=== A focus on different types of metamaterials ===

In nacre good mechanical properties are created through the interleaving of solid unstructured bio-minerals with protein-layers. 
But in [[gemstone metamaterial technology]] good mechanical properties shall be engineered by nano-structuring (bio)minerals with atomic precision. 

One can think of it as:
* [[gem-gum-tec]] targeting textiles made out nanoscale gemstone chainmaille.
* Mainstream biomineralization R&D aiming at laminated composite materials as e.g. nacre: slabs of horn-like proteins interspersed with slabs of single crystalline calc-spar

These are quite different goals.

=== Relevant overlap ===

{{todo|Investigate in how far parts of existing bio-mineralization R&D have overlap with work aiming at [[gem-gum-tec]].}}

== Misc ==

Due to the solvent there is a lot of viscous drag still preventing high throughput in this stage of development.

Conditions can be quite near to the assembled structure dissolving again. This:
* May help in assembly
* may put atomically precise synthesis in competition with other non atomically precise in solution nano-manufacturing techniques
* May quickly destroy the the atomic precision again due to too high dissolution and re-deposition at temperatures the solvent is not frozen
