DNA-Based Air Purification Systems Targeted Molecular Control of Indoor and Industrial Air

As buildings become more airtight, cities more polluted, and indoor environments more complex, the limitations of conventional air filtration are becoming increasingly apparent. Not all pollutants are equal. Not all molecules should be treated the same. The future of air quality lies not in removing everything, but in removing the right things.

This book explores a radically different vision: air purification at the molecular level using synthetic DNA. By leveraging the programmable nature of DNA strands, air purification systems can be designed to recognize, trap, neutralize, or even destroy specific airborne pollutants with unprecedented precision. This is not incremental improvement—it is a paradigm shift.

The concepts presented in this book are intentionally futuristic. Some technologies discussed are emerging, others are speculative, and a few may still reside on the edge of today’s imagination. Yet all are grounded in real scientific principles already transforming medicine, materials science, and nanotechnology.

The goal of this book is not to predict the future perfectly, but to provoke new ways of thinking about air, buildings, and environmental control. If air can be programmed, then buildings themselves become living systems—responsive, intelligent, and protective of human health.
