Virtual Biochemistry Lab Assistant

About the Project

The most challenging part of performing practicals in biochemistry is solution preparation — calculating molarity, volumes, moles, and dilutions repeatedly. These calculations are time-consuming and prone to errors, especially for students or early-stage researchers.

To simplify this, I created the Virtual Biochemistry Lab Assistant, a tool that performs essential lab calculations instantly, providing accurate preparation steps for solutions, dilutions, and reagents. This allows researchers to focus more on the experiment itself, rather than manual calculations.

Inspiration

During my practicals, I noticed that manual calculations were slowing down experiments. I wanted a tool that could:

Automate solution calculations
Reduce errors
Save time
Help students and researchers focus on experiments

This project combines computational assistance with real lab workflows, bridging theory and practical needs.

What I Learned

Streamlit for interactive web apps
Python for scientific calculations (moles, molarity, dilution factors)
Session management to simulate step-wise lab workflows
Visualization of lab results and preparation steps
How to design a tool for real user workflows in science

How I Built It

Built with Python 3.13
Streamlit for the interactive UI
NumPy & Pandas for calculations and data handling
Used real lab formulas for:
- Molarity: \( M = \frac{n}{V} \)
- Dilution: \( C_1 V_1 = C_2 V_2 \)
- Mass from moles: \( m = n \times MW \)
UI designed for a step-by-step workflow:
1. Sample preparation
2. Solution calculation
3. Dilution / reagent prep
4. Optional extensions (enzyme kinetics, gel electrophoresis, protein assays)
