Paper discussion: An Intelligent Microfluidic Processor for Biomedical Detection

Hello everyone, how are you guys?

Today I want to share a very interesting experience that I had developing this presentation on a scientific paper in the area of BioMEMs, which means Biomedical Microelectromechanical Systems.

It was a very challenging task, because one thing is to do some research in some papers to add information to your research, or to develop a project completely by your own, from the first concepts to the final product, another is to study a complex paper to make a presentation about a research that was not developed by you, and this is the great challenge.

When you have to present something developed by you, you have a complete knowledge of what was done, you know all the sources, the whole process, every stage through which you went through the development, until you get a conclusion, it means, you have the complete knowledge of the presented informations.

All of these presentations I have made at the Master’s degree here at Yonsei University have helped me to grow significantly, both improving my way of setting and planning them, and improving my English and my way to present the information.

In case you don´t know, my mother language is Portuguese, and here I highlight two important points in relation to these presentations.

1) Presenting in a language in which you are not a native speaker is already a great challenge, because you often end up putting some language addiction in Portuguese, no matter how fluent you are in english, and sometimes even one word or another comes out in your native language.
2) Talk about a subject that you did not participate in the project. For this, it is necessary to study the article very well until the whole development process and concepts are very clear for you, making it possible to structure a good presentation giving due relevance to the subjects addressed in the paper.

In the midst of so many challenges of getting a master’s degree abroad, we must always focus on both the studies and the presentation. I have no doubt that the best recipe for a good presentation is always BE PREPARED. One of the things that helps me learn the most is to write notes on the whole content, so that it is easier to understand the processes and create connections in the mind that will be extremely valuable and indispensable in the presentation.

Ultrasound Software Project

Hello everyone. This is a short video that shows the result of one of my projects on my master’s degree at Yonsei University – South Korea.

This is a final project of Ultrasound class. We were asked to develop an Ultrasound Simulation Software in MatLab, using a base code given by professor, and the main purpose of this project is to get knowledge and understand about how the Ultrasound Equipment works.

Many processes are involved like transducer, matrices, physics, calculus and so on. Mat Lab was used with GUI to create the graphic interface.

In one of our classes, the professor bring a portable Ultrasound System that works with an App on the iPad and the transducer works via Bluetooth. The average price of this product is around $5.000,00.

This kind of equipment is very useful to be used in remote areas where you can not carry a big equipment like the ones used in the hospital because is too big and too heavy.

Nanoscale Drug Delivery System (DDS) Presentation | Yonsei University | South Korea

Hello everyone. This is a presentation about Nanoscale Drug Delivery System (or Nano DDS) using PEGylation, a technique used on cancer treatment with nanotechnology by surrounding and protecting the drug with polymer Polyethilene Glycol to reduce the immunogenicity inside the body.

Immunogenicity is the ability of a particular substance to provoke an immune response in the body of a human or other animal. The immunogenicity can be divided in Wanted and Unwanted.

The main purpose of the process is to accumulate the drug only in the target, which means, reach the cancerous tissue and accumulate in its leaky blood supply.


1 – Protection and extended circulation times, targeting to specific cells and EPR effect are important features of this DDS.

2 – Reduced Immunogenicity improves the circulation times of the drug.

3 – Multiple injections can stimulate the formation of antibodies against the drug.

Sensory Physiology Presentation | Yonsei University – South Korea

Hello everyone. As you know, the main purpose on this website is to share knowledge, so let’s do it.

This is one more presentation on my master’s degree at Yonsei University, and the subject is about Sensory Physiology, how the body sensors, neurons, axons and other structures work.

Check bellow the presentation slides:

Korea International Medical + Hospital Equipment Show (KIMES) 2018


From march, 15 ~ 18, 2018 it occurred the 34th Korea International Medical + Hospital Equipment Show (KIMES), at COEX in Seoul – South Korea.

KIMES is a really big fair that has a lots of Medical and Hospital Device companies in various fields of this segment.

My first impression was like a shock wave beating me due to tons of exhibitors, products, screens, machines and advanced technology. The big deal in this fair is to get knowledge about what is new in the Biomedical Engineering area, make some network, learn about the new mechanisms and procedures on diseases treatment like cancer, for example.

Many exhibitors let you test the equipments and devices, as you can see in the pictures, many people are using the products and getting their own conclusions about then.

All the professionals  are high skilled and well prepared to kindly teach you how their products work, it is great to get up to date with this new technologies. I tested one massage chair and a device used on cancer treatment using high frequency. The exhibitor just positioned one part on my neck and the other one on my wrist, and all the path between this points got really hot due to the high frequency, that, in his words, “destroy the cancerous tissue”. The massage chair took me 15 minutes of relaxation within the fair, what was really good because I was tired to walk through the 2 enormous floor of KIMES at COEX.

As all you know, I work in the Bio Processing Laboratory at YONSEI University (South Korea) and also do my master’s in Biomedical Engineering here, thus this is a great opportunity to learn more about this amazing area that helps a lot of people around the world and get up to date.

About Exhibition

“KIMES provides you with the opportunity to identify and confirm the great potential and prospect of the future medical industry as well as the latest medical industry trend as a venue where 1,200 domestic and overseas manufacturers show the new technology and new products. It will become the venue for the communication to present that latest medical information and technology to keep up with the fast developing medical market.”


Here is a little video that I produce in the fair just to show a little bit of this great event.

Leture:Magneto-tatic Bacteria can Dance, but can they delivery Therapeutics?

This  lecture occurred at Yonsei University – South Korea at Medical Industry Techno Tower in WONJU.

The researchers filled bacteria with magnetic nanoparticles (crystals) to do electromagnetic interactions with the organisms and control their movement in the environment, everything controlled by magnets.

Control this bacteria is already possible in a controlled environment as he shows on his lecture, but the question is: Can they delivery therapeutics to specific areas inside the body?

So far, the study proposes to make the movement and the next step is get results in drug delivery by the magneto-tatic bacteria.

You can check the very funny video from his laboratory bellow:
