Concepts in Biotechnology: From Ancient Brews to Modern Miracles
Exploring the fascinating history, groundbreaking science, and promising business frontiers of biotechnology
What is Biotechnology?
When you hear "biotechnology," you might picture scientists in lab coats manipulating DNA or developing cutting-edge medicines. While accurate, this view captures only a fraction of what biotechnology encompasses. At its core, biotechnology is the application of biological systems and organisms to develop products and technologies that improve human life and the health of our planet. From the beer and bread of ancient civilizations to the mRNA vaccines that combat modern pandemics, biotechnology has been an integral part of human progress for millennia 1 .
Market Growth
Today, biotechnology represents one of the fastest-growing and most transformative sectors of the global economy, with the market estimated at USD 1.744 trillion in 2025 and projected to exceed USD 5 trillion by 2034 2 .
Revolutionary Impact
This explosive growth reflects how biotechnology is revolutionizing everything from medicine to agriculture, energy production to environmental protection.
A Journey Through Time: The History of Biotechnology
The application of biotechnology dates back thousands of years, though the term itself wasn't coined until the 20th century. Our ancestors may not have understood the molecular processes behind fermentation, but they effectively harnessed biological systems to create useful products.

The term "biotechnology" itself was first used in 1919 by Hungarian agricultural engineer Károly Ereky 1 . The 20th century witnessed an acceleration of biotechnological discoveries, from Alexander Fleming's accidental discovery of penicillin in 1928 to the monumental achievement of the Human Genome Project in 2003 1 . Each breakthrough built upon previous knowledge, creating a cumulative effect that has dramatically accelerated progress in recent decades.
The Modern Biotech Landscape: Key Concepts and Frontiers
Today's biotechnology sector is characterized by rapid innovation across multiple domains. Several key concepts and trends are shaping the future of this dynamic field.
Artificial intelligence is revolutionizing biotechnology, delivering remarkable improvements in efficiency and success rates. According to a 2024 Deloitte survey, 60% of biotech executives plan to increase investments in generative AI, predicting up to 11% revenue growth and 12% cost savings for medtech industries 2 .
Companies using AI in clinical trials report 20-30% improvements in success rates along with 50% shorter trial durations 2 . The collaboration between Microsoft and Novartis in Switzerland demonstrates this trend, where AI and cloud analytics have accelerated project cycles by 40% 2 .
Bioconvergence—the integration of biology, engineering, computing, and AI—is reaching mainstream adoption 2 . This approach has led to innovations such as:
- Organ-on-a-chip technology: Microfluidic devices that simulate human organ functions, enabling more accurate drug testing while reducing animal use 2
- Digital twins: Virtual replicas of physical biological systems that allow researchers to run simulations and predict outcomes 2
- Advanced diagnostics: Biosensors and monitoring systems that combine biological components with digital technology
The global market for bioconvergence applications reached USD 32.86 billion in 2022 and is expected to grow to USD 60.7 billion by 2030 2 .
With increasing emphasis on environmental protection, biotechnology is evolving to offer more sustainable production methods. Green biotechnology focuses on developing biodegradable materials, recyclable systems, and circular economy principles 6 . Innovations in this space include:
- Bio-based plastics derived from renewable biomass sources
- Enzymatic recycling processes that break down plastics more efficiently
- CO₂ utilization technologies that capture and convert carbon emissions into useful products
- Bio-based materials that reduce dependence on petroleum-based resources 2

Inside a Groundbreaking Experiment: CRISPR in Space
In May 2019, a team of student researchers made history when their experiment became the first to use CRISPR-Cas9 gene editing technology aboard the International Space Station (ISS) 3 . This groundbreaking study provides a perfect case study of how modern biotechnology experiments are designed and conducted.
Experimental Objective
The student researchers—David Li, Aarthi Vijayakumar, Rebecca Li, and Michelle Sung—designed their experiment to investigate how DNA repair mechanisms function in space, specifically addressing damage caused by cosmic radiation 3 . Understanding this process is critical for protecting astronauts during long-term space missions and future interplanetary colonization.
Methodology: Step-by-Step
The experimental procedure on the ISS involved several sophisticated biotechnological techniques:
- DNA Damage Simulation: ISS crew members used CRISPR-Cas9 to create precise breaks in the yeast genome, simulating damage similar to that caused by space radiation 3 .
- DNA Amplification: After the DNA damage and repair processes occurred, crew members used a miniPCR machine to make copies of the DNA segments of interest through polymerase chain reaction (PCR) technology 3 .
- DNA Sequencing: The final step involved using minION sequencing technology to read the repaired DNA sequences and identify any changes or errors introduced during the repair process 3 .
This end-to-end experiment—from DNA manipulation to analysis—was notable for being conducted entirely in space, setting the stage for more complex biological research in microgravity environments.
Results and Significance
The experiment provided crucial insights into how DNA repairs itself in space, with particular relevance to damage from cosmic radiation 3 . The results advance our understanding of fundamental biological processes in space environments and could lead to:
- Improved radiation protection for astronauts during long-term spaceflight
- Enhanced safety measures for future space exploration and potential colonization
- Better understanding of DNA repair mechanisms that could have implications for cancer research and aging on Earth
This student-led project exemplifies how biotechnology continues to push the boundaries of what's possible, extending our scientific reach beyond Earth's confines.
