Classical View on Nonclassical Crystal Growth in a Biological Setting.

Area of Science:

• Biomineralization
• Materials Science
• Crystallography

Background:

• Nonclassical crystal growth, specifically crystallization by amorphous particle attachment, is common in biogenic minerals.
• Organisms leverage this process to control mineral formation, influencing morphogenesis and crystallographic texture for specific functions.

Purpose of the Study:

• To examine the driving forces and kinetics of amorphous particle attachment in biological crystallization.
• To establish distinct crystal growth mechanisms by comparing this mode to classical crystallization.
• To highlight the role of materials physics and chemistry in biomineral "Growth and Form".

Main Methods:

• Literature review and theoretical analysis of crystallization by amorphous particle attachment.
• Analogical comparison with classical molecule-by-molecule crystallization mechanisms.
• Examination of biomineralization processes in living tissues.

Main Results:

• Crystallization by amorphous particle attachment offers organisms precise control over mineral formation.
• Distinct mechanisms differentiate nonclassical (particle-based) from classical (molecule-based) crystallization.
• Material properties significantly influence the "Growth and Form" of biogenic minerals.

Conclusions:

• Understanding amorphous particle attachment is key to bioinspired and biomimetic synthesis of functional materials.
• The physics and chemistry of materials are fundamental to controlling biomineralization.
• This nonclassical pathway allows for sophisticated control over mineral structure and function.
