Nanostructures in Nature

چکیده
All natural structures are created from their molecular precursors and are thus hierarchical. Every natural structure is built up from sub-structures that are of the nano-sized range. We are thus surrounded by nano-materials. Our own body is a perfect example of a nano-structured material. Every single part of the body is built up from nanostructures which have completely different structural arrangements that decide their functionality. The DNA structure that exists within the nucleus of a cell is one such nanostructure whose sole objective is to store and replicate information. Even the energy in the system cell is stored in the form of easy-to-manipulate bonds within nanostructures formed by Adenosine Tri – Phosphate (ATP) and Adenosine Di-Phosphate molecules (ADP). A Nano-structured membrane that forms the cytoskeleton of a cell performs yet another type of function: regulation of ion and molecular transport across the cell boundary.

Enzymatic Self-Assembly of Nanostructures for Theranostics
Self-assembly of small molecules or macromolecules through non-covalent or covalent bonds to build up supramolecular nanostructures is a prevalent and important process in nature. While most chemists use small molecules to assemble nanostructures with physical or chemical perturbations, nature adopts enzymes to catalyze the reaction to assemble biological, functional nanostructures with high ef...

متن کاملThe remarkable difference between surface and step atoms in the magnetic anisotropy of two-dimensional nanostructures.
The original magnetic properties of nanometre-sized particles are due to the distinct contributions of volume, surface and step atoms. To disentangle these contributions is an ongoing challenge of materials science. Here we introduce a method enabling the identification of the remarkably different contributions of surface and perimeter atoms to the magnetic anisotropy energy of two-dimensional ...
متن کاملIn vivo cloning of artificial DNA nanostructures.
Mimicking nature is both a key goal and a difficult challenge for the scientific enterprise. DNA, well known as the genetic-information carrier in nature, can be replicated efficiently in living cells. Today, despite the dramatic evolution of DNA nanotechnology, a versatile method that replicates artificial DNA nanostructures with complex secondary structures remains an appealing target. Previo...
