Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Scientists have developed an algorithm to build 3D nanoparticles called
A
DNA origami
B
DNA process
C
DNA tecnique
D
DNA procedure
Explanation: 

Detailed explanation-1: -Three-dimensional nanomaterials (3D) are materials that are not confined to the nanoscale in any dimension. This class can contain bulk powders, dispersions of nanoparticles, bundles of nanowires, and nanotubes as well as multi-nanolayers.

Detailed explanation-2: -Materials that are nanoscale in all three dimensions are considered to be 3D nanomaterials. These include quantum dots or nanocrystals, fullerenes, particles, precipitates, and colloids.

Detailed explanation-3: -Solvent evaporation technique is very commonly used for the preparation of polymeric nanoparticles.

Detailed explanation-4: -Generally, the most common 3D nanostructures refer to 1) 3D spatial ensembles of 1D (such as nanowires, nanotubes, nanorods) and/or 2D (such as nanosheets, nanoflakes) nanostructures; 2) 3D nanoporous structures; and 3) 3D hierarchical nanostructured materials.
