Emerging Biomedical Engineering Technologies

By Ken Roberts 7 June, 2023 3 mins read

The emergence of nanolabs on a chip provides the foundation for diagnostic biomarkers and point-of-care technologies. Organs-on chips mimic the human physiology. Biomedical engineers also have new possibilities with 3D printing. Here are some examples. Each of these have a major impact on the field biomedical engineer. Personalized medicine, bioengineering and nanomedicine are key engineering trends to keep an eye on.

The foundation of diagnostics biomarkers or point-of–care technologies is provided by Nanolabs on a Chip

The new test for oral carcinoma will measure several morphological characteristics like nuclear to cytoplasmic space ratio, roundness in cell body and DNA contents. One portable device is required for the test, which includes disposable chips and reagents used to detect DNA or cytoplasm. It can be used in certain situations to map surgical margins, or to monitor recurrence.

Combining giant magnetoresistive spinvalve sensors with magnetic nanoparticle tags, they create a powerful combination. They allow for rapid detection of a specific biomarker in as little as 20 minutes. This technology is ideal for point of care diagnostics because it allows for rapid analysis. This technology can detect multiple biomarkers simultaneously. This is a critical benefit of point-of-care diagnostics.

Not only are portable diagnostic platforms necessary to solve the issues of point–of-care environments, but they also address other challenges. Most diagnoses in developing countries are based on symptoms. However, in developed countries, molecular testing is increasingly being used to make diagnosis. Portable biomarker platforms are needed to extend diagnostic capability to patients in developing countries. NanoLabs can meet this need.

Organs-on-chips simulate human physiology outside of the body

An organ-on chip (OoC), is a miniature device containing a microfluidic system that has networks of hair-fine microchannels. These microchannels allow for the manipulation and manipulation of tiny volumes of solution. These tiny tissues have been designed to imitate the functions of human organisms. OoCs have many applications, but two areas of focus for future research are organ-on-chip therapies and biomarkers.

Multi-organ-onchip devices can include four to ten organ models. They can also be used for drug absorption studies. It comes with a transwell culture insert and a flowing system for drug molecules exchange. The multi-OoC device connects multiple organ models to cells culture media. The organs of the chip can also be connected via pneumatic channels.

3D printing

3D printing has enabled a variety of biomedical engineering applications to emerge. These include biomodels and prostheses, surgical tools, scaffolds, tissue/tumor chip, and bioprinting. This Special Issue examines the latest developments in 3D printers and their applications to biomedical engineering. Learn more about the latest innovations in 3D printing and how they can benefit patients around the globe.

The use of 3D printing in biomedical applications is transforming the manufacturing process of human organs and tissues. It can print entire parts of the body and tissues directly from patient cells. The University of Sydney pioneered 3D bioprinting for medicine. Many patients with heart problems suffer from a poor performance of their hearts. While heart transplants have been performed by surgery, 3D printed tissues might change the course of this procedure.

Organs-on-chips

Organs on-chips (OoCs), systems that contain engineered, miniature tissues mimicking the physiological functions a human organ, are called Organs-on Chips. OoCs offer a range of uses and have been gaining attention as the next generation experimental platforms. They can be used to study pathophysiology and human diseases, as well as to test therapeutics. During the design phase, many factors will be important. These include materials and fabrication methods.

Organs-on-chips are different from real organs in many ways. The microchannels within the chip permit the distribution and metabolism. The device itself is made out of machined PMMA (etched silicon). The channels are well-defined and allow for the inspection of each compartment. The liver and lung compartments are populated with rat cell lines. The fat compartment is unaffected by cell lines. This is more representative of the drugs that enter these organs. Peristaltic pumps support both the lung and liver compartments by moving the media from one to the other.

FAQ

Is engineering a good career choice?

Engineering What?

Engineering, in short, is the application scientific principles to make useful things. Engineers use their knowledge of mathematics and science to design and produce machines, vehicles.

Engineers are involved in many areas, including research and development, production maintenance, testing, quality assurance, sales, marketing management, consulting law, politics, finance and human resources administration.

An engineer has various responsibilities, including designing and building products, systems, processes, and services; managing projects; performing tests and inspections; analyzing data; creating models; writing specifications; developing standards; training employees, supervising workers, and making decisions.

Engineers can specialize in certain fields, such as mechanical, electrical, chemical, civil, architectural, computer, biomedical, manufacturing, construction, aerospace, automotive, nuclear, petroleum, mining, forestry, geology, oceanography, environmental, and more.

Some engineers are more interested in specific types of engineering than others, including aeronautics and biotechnology, computing, electronics energy, industrial, maritime, medicine, nuclear, robotics space transportation, telecommunications and water.

Is engineering hard to learn?

It depends on your definition of "hard". If you mean it is difficult, then you can say yes. However, if you mean boring, then you should not. Engineering is not difficult, but it does require a lot maths and physics.

You can learn to do something if you really want it. Engineers don't need to be engineers to succeed.

Engineering is fun, as long as it's something you like.

Engineering is not difficult if one knows everything. This is false.

Engineers can be boring because they haven’t tried it all.
