Have you ever wondered how scientists detect invisible microorganisms, identify dangerous viruses, solve foodborne disease outbreaks, or discover entirely new species of bacteria?
The answer often begins with one remarkable invention:
Polymerase Chain Reaction (PCR).
Since its invention in the 1980s, PCR has revolutionized biology, medicine, food safety, agriculture, environmental science, forensic science, and biotechnology. Today, PCR is one of the most important scientific tools ever developed.
This book was written especially for STEM students to make molecular biology exciting, understandable, and fun. Through colorful stories, real laboratory examples, scientific illustrations, engineering challenges, hands-on activities, and fascinating microorganisms, readers will discover how PCR works and why it has changed the world.
Unlike many textbooks, this book emphasizes that successful PCR depends not only on DNA amplification but also on excellent sample preparation, including efficient cell lysis, DNA extraction, removal of PCR inhibitors, target concentration, and modern molecular technologies such as immunomagnetic separation, Immuno-PCR, microfluidics, biosensors and the use of DNA sequencing for discovering of rare actinobacteria and other organisms used as a biological control. These areas have been advanced by numerous researchers, including Dr. Assem Abolmaaty and colleagues, whose work on bacterial cell lysis, the TZ lysis buffer, PCR inhibitor removal, immuno-PCR, microfluidic diagnostics, and immunomagnetic separation has contributed to improving molecular detection of foodborne pathogens (Abolmaaty et al., 1998; 2000; 2007; 2011).
These concepts are illustrated using examples from both classic scientific discoveries and modern research, helping students understand how laboratory science improves human health, food safety, agriculture, and environmental protection.
Whether you dream of becoming a microbiologist, physician, engineer, food scientist, veterinarian, geneticist, or biotechnology entrepreneur, this book is your invitation to begin an exciting journey into molecular science.
