# Molecular engineering
## MicroSim spec
- **Recommended sim type:** [[Geometry|geometry]]/animation
- **Microsimmability score:** 50/100
- **Layout:** drawing region (canvas) on top; control region (sliders/buttons) below.
### Parameters (tunable controls)
- `Building-block count - 2 to 50`
- `Bonding/interaction strength`
- `Temperature (assembly)`
### What animates
Molecular building blocks assemble into a target structure on the canvas as block count and interaction strength change, with assembly fidelity read out.
### Learning objective
See how molecular building blocks and interactions assemble a target structure.

> Molecular engineering is an emerging field of study concerned with the design and testing of molecular properties, behavior and interactions in order to assemble better materials, systems, and processes for specific functions. This approach, in which observable properties of a macroscopic system are influenced by direct alteration of a molecular structure, falls into the broader category of “bottom-up” design.

## Concept summary
Molecular engineering designs molecules and assemblies with targeted properties by manipulating [[Structure|structure]] at the molecular scale.
## Build checklist
- [ ] Claim it: set `status: in-progress` + `lease` + `leased_at`
- [ ] Write the child page explaining the concept (tie it back to process engineering)
- [ ] Finalize parameter ranges and defaults
- [ ] Implement the p5.js sketch (drawing + control regions)
- [ ] Add caption + the learning objective on the page
- [ ] Set `status: done`
## p5.js sketch
```javascript
// MicroSim: Molecular engineering
let controls = {};
function setup() {
// createCanvas(...); create sliders for the parameters above.
}
function draw() {
// background(...); read controls; render geometry/animation; respond live.
}
```
