Summary
Coli Bond uses synthetic biology and DNA storage for secure data transmission. This system offers controllable information transfer and irreversible data destruction, enhancing security for DNA-encoded information.
Area of Science:
- Synthetic Biology
- Biotechnology
- Information Storage
Background:
- Traditional data storage faces challenges like security risks and high costs.
- DNA storage offers high density and stability but lacks secure transmission methods.
Purpose of the Study:
- To develop a secure and controllable platform for DNA-encoded information storage and transmission.
- To integrate DNA storage with synthetic biology for dynamic data control.
Main Methods:
- Engineered an auxotrophic Escherichia coli strain with a caffeine degradation pathway.
- Implemented a caffeine concentration and temperature-regulated information transfer system.
- Incorporated a temperature-sensitive self-destruction mechanism for data security.
Main Results:
- Demonstrated system stability and reliability in real-world conditions, including commercial beverages.
- Confirmed high transmission efficiency during initial contact.
- Observed a rapid decline in strain viability after multiple transfers, enhancing security.
Conclusions:
- Coli Bond provides a secure and adaptable platform for DNA-encoded information.
- The integration of DNA storage and synthetic biology advances information storage and transmission technologies.

The genome of most prokaryotic organisms consists of double-stranded DNA organized into one circular chromosome in a region of cytoplasm called the nucleoid. The chromosome is tightly wound, or supercoiled, for efficient storage. Prokaryotes also contain other circular pieces of DNA called plasmids. These plasmids are smaller than the chromosome and often carry genes that confer adaptive functions, such as antibiotic resistance.

The human immune system is a complex network of cells, tissues, and organs that work together to defend the body against bacterial infections. It consists of various immune cells, each playing a specific role in the defense mechanism.
Phagocytes
Phagocytes are the frontline soldiers of the immune system. They include neutrophils and macrophages. Neutrophils are the most abundant type of white blood cell and are quickly mobilized to the site of infection. Macrophages are larger cells that patrol...

Prokaryotes are small unicellular organisms that include the domains — Archaea and Bacteria. Bacteria include many common microorganisms, such as Salmonella and E. coli, while the Archaea include extremophiles that live in harsh environments, such as volcanic springs.
Like eukaryotic cells, all prokaryotic cells are surrounded by a plasma membrane, have genetic material in the form of single, circular DNA, a cytoplasm that fills the interior of the cell, and ribosomes that synthesize...

Bacteria and archaea are susceptible to viral infections just like eukaryotes; therefore, they have developed a unique adaptive immune system to protect themselves. Clustered regularly interspaced short palindromic repeats and CRISPR-associated proteins (CRISPR-Cas) are present in more than 45% of known bacteria and 90% of known archaea.
The CRISPR-Cas system stores a copy of foreign DNA in the host genome and uses it to identify the foreign DNA upon reinfection. CRISPR-Cas has three different...

The skin and mucous membranes serve as the primary line of defense against pathogens by providing both physical and chemical protection. These barriers are essential in preventing the entry and establishment of microbes, thereby maintaining the integrity of the host.
The outer layer of the skin, the epidermis, is a robust barrier comprising layers of closely packed keratinized cells. This dense arrangement prevents microbes from penetrating the body. The periodic shedding of epidermal cells...
