⚡ Introduction: Reading Proteins – A New Challenge in the Life Sciences and Engineering Technology
Proteins are considered the fundamental pillar of life, and they play a pivotal role in the functions of cells and tissues. However, understanding their structure and reading their sequence directly has remained a major challenge over the past decades, compared with DNA reading technology.
Recently, advanced technologies such as those being developed by UNOMR have emerged with the aim of revealing this “blind spot” in protein measurement, through sensitive devices that rely on precise engineering and nanoscale technologies, enabling the detailed reading of protein structure.
📌 Quick summary: In this article, we move on to discuss the engineering and technical difference between reading proteins and reading DNA, and we also explain the complex challenges, the working principle of the new reading devices, and their future impact on medicine and industry.
🔧 The Difference Between Reading DNA and Reading Proteins
DNA reading technology, or DNA sequencing, has expanded and been used in practice for more than two decades, and it relies on only four components: the nitrogenous bases (adenine, thymine, guanine, and cytosine). This relative simplicity helps in developing precise machines to read the sequence of these bases with relative ease.
In contrast, proteins are made up of long chains of amino acids that exceed 20 basic types, and there are also thousands of additional chemical modifications that occur on these amino acids, such as the addition of chemical groups, sugars, or phosphates, which greatly increases the complexity of their structure and function.
📊 Engineering and Measurement Complexity
- Number of biological letters: DNA has 4 letters, while proteins have more than 20 basic amino acids, and modifications increase the number to hundreds or thousands.
- Three-dimensional structure: Proteins are not just chains; they transform into complex three-dimensional forms with a specific function.
- Functional compatibility: The chemical modifications on a protein precisely determine its function, which makes the volume of data produced by protein measurement much larger.
🔹 Important point: All these factors have made protein measurement and the understanding of its structure a major engineering and analytical challenge, compared with DNA reading techniques.
🛡️ How Does the New Protein Reading Technology Work?
UNOMR technology relies on a device that uses nanoscale silicon chips that resemble electrical chips, filled with saline solutions, and measures ionic currents passing through very small pores (nanopores).
The protein to be measured is forced to pass through these pores, where the nature of the protein and its structure cause minute changes in the current, which are read by electronic circuits.
⚡ The Engineering Principle of Operation
- Ionic current measurement: A weak electric current passes through a saline solution inside the chips.
- Dynamic nanopores: The pore opening size can be controlled to suit diverse proteins.
- Digital reading: Current differences indicate the type and order of amino acids and chemical modifications.
📌 Technical summary: The combination of precision engineering, embedded systems, and specialized chemistry is what makes protein reading possible in a new way that is completely different from traditional biological laboratories.
📐 Future Engineering and Technical Applications in Industry and Medicine
As this technology advances, broad application possibilities emerge, especially in:
- The pharmaceutical industry: Testing and controlling biological drug molecules, such as antibodies, with precise ratios and specific modification requirements.
- Precise medical diagnosis: The possibility of developing devices for direct measurement of specific proteins in body fluids, which speeds up diagnosis and determines the appropriate treatments.
- Food and nutrition: Analyzing proteins in foods with precision to improve quality and detect contamination or fraud.
- Scientific research: Enabling scientists to understand proteins and their functions in new ways, and supporting the development of drugs and advanced treatment technologies.
⚠️ Safety warning: The new devices require highly controlled laboratory environments and operating precision to ensure measurement safety and accuracy, which poses challenges in practical application.
🔁 Linking Electrical Engineering and Biology in This Technology
Working on protein reading is not only a challenge in biology and molecules, but also involves complex technical and engineering applications:
- Electronic circuit design: To measure and interpret very small electrical signals accurately.
- Microfabrication design: Developing precise nanopores from solid materials, not only biological materials, which opens the door to modifying electrical and mechanical properties.
- Environmental control: Using precise measurement and control techniques for temperature, humidity, and chemical materials.
- Data analysis software: Relies on advanced algorithms to analyze the intensity of electrical signals and link them to protein structure.
🔹 Engineering point: Understanding these relationships and the integration between engineering skills and biochemistry is the key to the success of such technical projects.
📊 Devices and Measurements: From the Laboratory to Practical Applications
Reading depends on sensitive measurement devices whose principles resemble Multimeter devices for measuring electric currents and voltages, but they are dedicated to measuring ionic currents within very narrow and precise ranges, requiring isolated and advanced technologies.
It is also important to have control systems to regulate the environmental conditions inside the chip and ensure signal stability and prevent interference from electrical noise.
⚡ Technical note: It may be necessary to integrate micro-sensors with electrical protection systems to prevent the effects of external factors such as electromagnetic interference.
🛠️ Engineering Challenges in Developing Protein Reading Devices
- Size and precision: Manufacturing nanopores at the appropriate size with high precision to accommodate all types of proteins.
- Fine electrical signals: Identifying small changes in current associated with changes in the protein’s arrangement, size, or modifications.
- Calibration and reliability: Producing devices that can be rigorously calibrated to obtain repeatable measurements.
- Ease of use: Developing systems that add simple operating interfaces, allowing technicians and trainees to handle the devices efficiently without the need for expert intervention.
📌 Practical summary: These engineering choices represent the essence of progress in modern measurement devices, and they require multiple learning opportunities across disciplines for electrical engineering students and trainee technicians.
🎓 Educational Conclusion and Guidance for Students and Technicians
