Microfluidic Event in the North of Spain
The 19th of October , BIOARABA – Conference on Research and Innovation(the 17th Conference on Research OSI UNIVERSITY HOSPITAL ARABA / BIOARABA Research Institute, in collaboration with the Campus of Álava of the UPV / EHU) was held in Vitoria / Gasteiz, more precisely in the Palacio Europa, aimed at people who work on investigation and people who are interested in the topic of BIOTECHNOLOGY.
It has been a seminar directed by professionals who work on investigation and the citizens, who take advantage of the investigations that the companies carry out.
That is why, the citizens have had a great importance in this seminar, letting them choose the principal topic of the event, creating a bridge between professional people and stakeholders that do not know much about the topic, but moreover, are interested on it.
The seminar had two important points. On one hand, there were conferences where professionals take part, which were organized in “Workshops” and everybody give their opinion and experience about the topic. We worked on “NEW ANALYTICAL TECHNOLOGIES IN HEALTH”, been expertly managed by Arantxa Goicolea from UPV/EHU.
On the other hand, and as mentioned before, the citizens take part on the annual investigation award ceremony and they are also able to take part in the meeting of “Healthy aging, a health social and technological perspective” where the experts shared their opinion and knowledge about the topic.
One of our team member took part in this workshop talking about “New analytical technologies in health” together with, for example, Carmen Zugaza (Osakidetza),Javier Garaizar (UPV/EHU), Lourdes Basabe(UPV(EHU), Alberto Gómez (UPV), Carolina Núñez Domingo (UPV) or Raúl Pérez González (I+Med) and Jesica Ruiz Pérez (I+Med). Some of the topics discussed where Clinical analysis, immunological diagnosis or microfluidic systems.
Microfluidic Application: Cell Culture
Cell culture studies based on Microfluidics are said to provide a valuable complement to in vivo experiments, because it allows a more controlled manipulation of cellular functions and processes.
Even if obtaining a pure population of primary cells can be a difficult and hard process, it gives many advantages to work with it, such as;
1. Flexibility when designing the device, it gives the opportunity to adapt to the client’s needs.
2. It gives experimental flexibility & control, which means that is possible to control and make different experiments while creating.
3. Moreover, a low number of cells are needed, because microfluidic cell culture devices reduce the cell population to a few hundred cell, or sometimes, even to individual cells. This increases the spatial and temporal resolution for the experiment.
4. Single cell handling and Real-time on chip analysis: This point is related to the previous, one, because microfluidic cell culture includes the ability to more closely mimic a cell’s natural microenvironment, working directly on chip , and moreover, working in real time.
5. Microfluidic cell culture devices also make it possible and reliable to study complex cellular behaviour, such as the relationship between single cell movements and collective cell migration.
6. Related to the real time on chip analysis, this system gives the opportunity and advantages of precise control of experimental conditions.
7. Moreover, microfluidic cell culture is able to incorporate analytical biosensors into the culture platform.
Microfluidics Application: Cell Culture
CELL CULTURE : As known, a single cell is what builds the human life, and the genetic material of all those cells in the human body hold the secret to inherited diseases, such as cystic fibrosis, Alzheimer or other complex diseases.
Taking this into account, Cell cultures and DNA can be established from blood or small fragments of tissue (biopsies).
In its simplest form of cell culture, it involves the dispersal of cells in an artificial environment composed of nutrient solutions, a suitable surface to support the growth of cells, and ideal conditions of temperature, humidity, and gaseous atmosphere. These systems are needed for aa researcher to measure the response of the cell’s alterations in culture, prospective drugs, the presence or absence of other kind of cells and viruses precisely.
Cell culture, what for?
The mass culture of animal cell lines is fundamental to the manufacture of viral vaccines and many biotechnology products. And the use of cell culture has clear advantages, such us:
Microfluidic Application in the Neuro field
An innovative project with Hospital de Valdecilla(IDIVAL), together with microLIQUID and CSIC reaches the centre of the technology talent, the MIT in Boston.
A project lead by the Head of Clinical Neurophysiology and the attending physician of Intensive Care Medicine of HUMV and IDIVAL, has been one of the 15 international teams selected by MIT #Idea2Global program, developed by the prestigious Massachusetts Institute of Technology (MIT) in Boston (USA). The project has been developed in close collaboration with Instituto Cajal and Microliquid.
The selected teams have won 6 months of training and mentoring of their innovation projects with professors at MIT and other world-class institutions. The program will provide intensive training in innovation methods, development of collaborative projects and specific mentoring team. Moreover, it will provide the experience to help the projects to change from being a new idea to work in the real life.
WHICH IS THE PROJECT?
The idea of the project of great level of technology comes out from Valdecilla, and through the “Foundation for Innovation and Foresight in Health in Spain” (Fipse), which is a non-profit private entity on health research with the Ministry of health and pharmaceutical companies coverage, has gone to the Technology institute in Massachusetts (MIT) in Boston.
The aim of it is to prevent the supervening brain damage while a patient is in coma. And the way to achieve it is the creation of an innovative electrode capable of detecting phenomena which cause the death of neurons that exacerbate the initial injury.

Microfluidic Event in Spain
Microliquid has attended the “8th International meeting in Biotechnology “ from the 28th to the 30th of September, held in BEC (Bilbao). It is important to say that more than 850 companies went to the meeting and almost the 34% of the attending companies where international, coming from 28 different countries. Moreover, during these 3 days, there have been more than 3.300 meeting or partnerings, with more than 2.000 people of different companies taking part.
Biospain is a biennial event organized by ASEBIO, the Spanish association of Biotechnology Companies, in collaboration with other organizations, in this case, the Basque Business Development Agency. Due to the increasing international rivalry, this meeting is important for companies working in the Biotechnology field, in order to expand what they do and learn from other companies. BioSpain 2016 has had also a greater presence of USA companies and organizations, being USA the guest country in this eighth edition. People form the states of Maryland, Massachusetts, North Carolina, Pennsylvania, Texas, Virginia and Puerto Rico have attended the meeting. Moreover, this year the participation of national companies has raised, more specifically Galicia, Basque Country, Cataluña, Valencia or Baleares. Some of the topics discussed at BioSpain 2016 are oncology, Alzheimer, food, vaccine or new diagnostic methods.

Microfluidics Application: Biomarker for Detection through Microfluidic Chips
Biomarkers are the physiological,biochemical or morphological changes that occur as a result of exposure,generally, to a toxic substance. The Biomarkers are only the measures/responses at molecular and cellular level because it is the perfect situation to study the cause-effect relationships and mechanisms of action of these substances.
It is important to understand their mechanisms of action to develop medical or detection devices. Other features that allow its use is the reproducibility, sensitivity, specificity and especially they present a very fast response time for detection, among other things.
Due to these features it is an instrument widely used both in the environmental field and in the health industry.
It is essential that the biomarker response time is short , so that it can be used as “early warning system” and if also shows a diagnostic value, it can then be used predictively.
We can distinguish two types of biomarkers, biomarkers that indicate exposure and those that indicate damage from exposure.
Microfluidics Manufacturing: DRIE Process (Deep reactive ion etching)
The DRIE – Deep reactive ion etching: In this attack , a highly anisotropic(focus on one direction) etching, we can define the desired structures on silicon with the heights defined before. It is a used to create also through holes and estructures in wafers / substrates, with typically high aspect ratio.
The definition obtained with this attack over the Silicon is very good. We use the Bosch process to do it.
First we passivate with metals the wafer parts you want to keep and then do the attach with the ion plasma which removes the silicon from the non passivated parts.
To do the DRIE process , we use a special machine you can see in the photo below.
Microfluidics Manufacturing: Anodic Bonding
The Bonder enables Anodic Bonding (Sealing) between a Silicon wafer and a Crystal Wafer. This seal is used primarily for connecting silicon / glass and metal / glass through electric fields.
The requirements for anodic bonding are cleaned surfaces availability on both wafers and the atomic contact between the binding substrates through an electrostatic field should be strong enough
