Biological Engineering 2025 Breakthroughs and Perspectives

Biological engineering, also known as bioengineering, encompasses biological systems engineering and is a field that employs physical and mathematical principles to address challenges in the life sciences. It utilizes both analytical and synthetic engineering techniques.

The distinction between biological engineering and biomedical engineering can often be ambiguous, as many academic institutions interchangeably use the terms bioengineering and biomedical engineering.

In this framework, while conventional engineering focuses on the analysis, design, and production of inanimate tools, structures, and processes through physical and mathematical sciences, bioengineering applies these same scientific principles to explore various facets of living organisms.

Advantages and Applications of Biological Engineering

This powerful field is primarily focused on addressing and resolving issues concerning human and animal health, as well as biological systems that are essential for food and pharmaceutical production. Biological engineering is an engineering discipline that employs the technological application of biological systems, living organisms, or their derivatives to innovate or alter products or processes for designated purposes. It integrates knowledge from natural sciences such as chemistry, physics, and mathematics, along with specialized fields that emerge from their convergence, including biochemistry, bioengineering, and biotechnology.

In many nations, this discipline is recognized as a career in biotechnology; however, countries like Colombia, Uruguay, Chile, and more recently Mexico, offer it as a distinct professional path. While its applications are predominantly linked to human health, the scope of the field is broader. For instance, biomimicry—or biomimetics—focuses on deciphering how living organisms, through an extensive evolution process characterized by trial and error, have navigated challenges in the past, aiming to replicate these solutions in artificial systems. Additionally, systems biology employs reverse engineering principles to enhance our understanding of the structure, function, and intricate operations of complex biological systems.

Biological engineering stands as a scientific discipline rooted in biological sciences, akin to how chemical engineering, electrical engineering, and mechanical engineering are grounded in chemistry, electricity, magnetism, and classical mechanics, respectively. This field can be differentiated from traditional biology or classical engineering by its approach: biological studies often utilize streamlined methodologies, examining systems at their most fundamental levels, which leads to the development of tools such as functional genomics.

Engineering methodologies leverage traditional design frameworks in a constructivist manner to innovate new devices and technologies. Biological engineering integrates these techniques, employing shorthand to identify, comprehend, and systematize the fundamental components of biological matter, which are then amalgamated to create novel solutions.

This scientific knowledge is pivotal in addressing real-world challenges. While bioengineered systems are instrumental in managing information, constructing materials, facilitating chemical processes, generating energy, producing food, enhancing human health, and rehabilitating the environment, they are still less advanced compared to electrical or mechanical systems.

However, Professor Doug Laufenberg from MIT asserts that biological engineering encompasses a vast spectrum, applying engineering principles across various systems of differing complexities, ranging from the molecular scale to large ecosystems.

Biological engineering and biomedical engineering are not entirely overlapping; much like there are non-biological applications in medicine, biological products are also utilized for non-medical purposes. ABET, the organization that accredits engineering programs in the United States, differentiates between biomedical and biological engineering, although the distinctions are minimal.

Biomedical engineers are required to complete life science courses that cover human physiology and gain hands-on experience in measuring biological parameters. In contrast, biological engineers must undertake science courses and acquire experience in measuring parameters for both living and non-living systems, typically including standard engineering courses such as thermodynamics, fluid mechanics, statics, and material properties.

The term bioengineering was introduced by the renowned English scientist and broadcaster Heinz Wolff in 1954. It encompasses the application of plant life in civil construction and can be utilized for environmental enhancements, including soil protection, slope stabilization, watercourse management, coastal defense, windbreaks, vegetation barriers, acoustic shields, visual screens, and ecological restoration.

The first academic program dedicated to biological engineering was established at the University of Mississippi in 1967, marking the inception of biological engineering education in the United States. Since then, prestigious institutions like MIT and the University of Utah have launched their own programs.

Biological engineers, or bioengineers, harness the principles of biology along with engineering tools to develop practical, impactful, and economically sustainable products.

This field integrates knowledge from various pure and applied sciences, including mass and heat transfer, chemical kinetics, biocatalysts, biomechanics, bioinformatics, process separation and purification, bioreactor design, surface science, fluid mechanics, thermodynamics, and polymer science.

Their work spans the design of medical devices, diagnostic tools, biocompatible materials, renewable bioenergy solutions, ecological engineering, and more, ultimately enhancing societal quality of life.

In essence, biological engineers strive to emulate biological systems to innovate products or to manipulate and manage biological systems, enabling them to replace, augment, or sustain chemical and mechanical processes.

Their expertise extends to other engineering and technology domains, such as the genetic modification of plants and microorganisms, bioprocess engineering, and biocatalysis. Given that various engineering disciplines intersect with living organisms—such as prosthetics in mechanical engineering—the term biological engineering can encompass a broader range, including agricultural engineering and biotechnology.

Many traditional agricultural engineering departments worldwide have rebranded themselves as biological or agricultural engineering and biosystems engineering departments. In certain academic contexts, biological engineering is synonymous with bioengineering, while biomedical engineering is also referred to as bioengineering, highlighting the rapid evolution of this dynamic field, particularly in fluid categorization.

Biological engineering and bioprocess engineering

Biological engineering and bioprocess engineering encompass a powerful specialization in biotechnology and chemical engineering.

This field focuses on designing and developing equipment and processes to produce a wide array of products, including food, feed, pharmaceuticals, nutraceuticals, chemicals, polymers, and paper, all derived from biological materials.

Bioprocess engineering integrates mathematics, biology, and industrial design, covering diverse aspects like fermenter design and operational analysis. Additionally, it involves examining various biotechnological processes utilized in large-scale production industries, aiming to enhance both the yield and quality of the final products while leveraging biological diversity.

Genetic engineering

Genetic engineering, also known as synthetic biology and horizontal gene transfer, refers to the deliberate alteration of an organism’s genome through advanced DNA technology. This process involves inserting foreign DNA or synthetic genes into the target organism. While the incorporation of new DNA bypasses traditional genetic techniques, conventional breeding methods are typically employed for the propagation of these recombinant organisms.

Biomedical engineering

Biomedical technology encompasses various domains such as biomedical diagnostics, therapy, biomechanics, and biomaterials, integrating engineering design principles with medicine and biology.

This discipline aims to close the divide between engineering and healthcare, merging innovative design and problem-solving with medical and life sciences to enhance health outcomes in diagnosis, monitoring, and treatment.

Recently, biomedical engineering has solidified its status as a distinct field, evolving from an interdisciplinary specialization into an established domain of its own. This transition is typical as emerging fields distance themselves from their foundational disciplines. Much of the work within biomedical engineering focuses on research and development, spanning a diverse array of subfields.

Prominent biomedical engineering applications include the development of biocompatible prostheses, various diagnostic and therapeutic medical devices ranging from clinical equipment to micro-implants, and common imaging equipment such as magnetic resonance imaging and electroencephalography, tissue growth regenerative, drugs, and therapeutic biological products.
