NANBIOSIS Scientific Women in the International Day of Women and Girls in Science

Today February 11 is the International Day of Women and Girls in Science, a day to raise awareness of the gender gap in science and technology.

According to the United Nations, while yet women and girls continue to be excluded from participating fully in science, science and gender equality are vital to achieve the internationally agreed development goals, including the 2030 Agenda for Sustainable Development. Thus, in recent years, the international community has made a great effort to inspire and promote the participation of women and girls in science.

NANBIOSIS wants to acknowledge  the efforts made by scientific women who struggle every day to contribute their bit to Science and highlight their essential role in nowadays research. Especially we want to recognize the work of scientists women involved in our units, whatever is the nature of their contribution: technical, scientific development, management, coordination, direction, etc; just to mention some examples:

Researchers of NANBIOSIS U9 awarded for a work on scaffolds for dental regeneration

Researchers Manuel Arruebo and Víctor Sebastián, from the CIBER-BBN group led by Jesús Santamaría (NFP) at the University of Zaragoza, that coordinates NANBIOSIS Unit 9 Synthesis of Nanoparticles, have received the second prize of the Resomer Awards granted by the company Evonik, a international recognition to competitiviness.

Their work “Promoting bioengineered tooth innervation using nanostructured and hybrid scaffolds”, has been published in the journal Acta Biomaterialia 50 (2017) 493-501. In this work, the researchers of the CIBER-BBN manufactured biodegradable materials such as scaffolds to promote dental regeneration. These scaffolds contained an immunosuppressive drug that, in addition to avoiding rejection after implantation, favored innervation. These implants were evaluated in vitro and in vivo at the French National Institute for Medical Research in Strasbourg, in the group of Nadia Jessel, demonstrating in animal models that these implants favored tooth regeneration and that the regenerated teeth were vascularized and innervated, both necessary characteristics to obtain a good regeneration.

The company Evonik AG is one of the largest chemical companies in the world with more than 36,000 workers and chemical plants in more than 30 countries. Its specialty is fine chemistry and one of its flagship products are biodegradable polymers.

Jesús Santamaría, interviewed in the Cadena Ser Radio, denounces the bureaucratic barriers that hinder research.

Jesús Santamaría, Scientific Director of NANBIOSIS Unit 9, Synthesis of Nanoparticles Unit, denounces the bureaucratic obstacles of the Law of Contracts, which are paralyzing the investigations whenever it is necessary to buy material or hire personnel.  His research against cancer, which received one of the most powerful European funding of more than two million euros, is stranded because of this rule, which requires to take out any purchase over 15,000 euros. “You can not do research like that,” Santamaría said. “In other countries there are no obstacles and we have to compete with them”

With the entry into force on March 9 of Law 9/2017 of November 8, scientists encounter importan important problems to use not only their basic budgets but also to use funds obtained in open and competitive calls, so they have money available to investigate that can not be spent.

This situation of Spanish research has been reviewed internationally, for example in an article published by the prestigious journal Science: Accounting rules hobble Spanish institutes 

Until now, spending limits were applied per researcher, project and year. (that is, public tenders or having to submit several budgets). Now the limit is computed at the institutional level. This makes it impossible, in practice, to execute budgets, given that once the border of 15,000 euros per institution is exceeded, the direct contract it is not possible but it is needed to undertake the procedures of a contest which can take months.

But all of this does not happen outside Spain, not even in Europe, even though this law is an adaptation of a European Directive. In the rest of the European Union, Science has been prevented from going through this “funnel”. Santamaria calls for a stronger reaction from the scientific community towards the administration.

These obstacles and their results in the R+D were explained in an article published in El Diario.es on April 4, titled “Why does the government make it difficult to carry out scientific research spending?”: “This measure, which may make some sense for laboratories Hospitals that carry out routine analyzes in a standardized manner are meaningless when we talk about independent research groups that work in very diverse areas within the same center, and that lack the administrative personnel necessary to manage this new form of bidding. make impossible, for example, the execution of expenses in other countries, something as common as the payment to a laboratory in North America for the performance of a chemical or genetic analysis: according to this law the foreign laboratory would have to be submitted to the contest. of billing of this type of services are tiny enough so that a laboratory i International, which is extremely busy with the processing of their samples and the calibration and maintenance of their equipment, bother to start the long and complex path of opting for a public tender so that a Spanish researcher can pay for the analysis of their samples. “

Conference on Nanotoxicity, next May 24, Parc Scientific of Barcelona

NANBIOSIS is organizing a Conference on Nanotoxicity in collaboration with Nanomed Spain and Materplat, next May 24 in the Parc Scientific of Barcelona, to debate about the efect of nanotoxicity of nanoparticles and nanotechnologies in health.

The increase of potential risks to health has created the new discipline of nanotoxicity, that is, the study of the toxicity produced by the effect of nanoparticles and nanomaterials. The objective of this day is to learn more about the lines that are being followed by researchers in the area of ​​nanotoxicity, the progress of different projects in this field, as well as existing tools to know and reduce the toxicity of nanoparticles and nanomaterials.

Nanotechnology intervenes in the design, production and use of structures and objects that have at least one of its dimensions in the scale of 100 nanometers or less. This science is allowing the achievement of advances in various areas with great repercussions for society.

However, manufactured nanoparticles can have properties and effects very different from those of the same materials in conventional sizes, which may pose new risks to the health of man and other species. Some nanoparticles, which are used as a vehicle for drugs to reach the desired cells in greater quantities, to reduce the side effects of the drug in other organs or both, have the same dimensions as certain biological molecules and can interact with them.

Gold nanoparticles can activate drugs inside tumors

Jesus Santamaría, Scientific Director of Unit 9 of NANBIOSIS has participated in a study that shows the ability of gold nanoparticles to generate in situ potent anticancer drugs from inert molecules thanks to a mechanism of elimination of terminal chemical groups that nanometric gold is able to catalyze. Gold is ideal for this catalytic role due to its high biocompatibility.

These results, published in the journal Angewandte Chemie, offer new hope in the fight against cancer and have been obtained thanks to the collaboration of scientists of Unit 9 of NANBIOSIS and, Víctor Sebastián, Silvia Irusta and Jesús Santamaría, with researchers from the Center for Cancer Research at the University of Edinburgh, led by Dr. Unciti-Broceta.

The work reveals the possibility of carrying out catalysis in biological means using tiny particles of gold. These gold nanoparticles, camouflaged in a resin microcapsule implanted in the brain of a zebrafish, have succeeded in catalyzing a chemical reaction generating fluorescent compounds.

Significant practical importance

“The main problem of chemotherapy treatments are the side effects in various organs due to the toxicity of the molecules that are used to fight cancer. For this reason, alternative routes are explored from nanotechnology, for example, transporting drugs to the tumor using nanoparticles or alternative treatments to drugs, such as hyperthermia, elevation of local temperature, obtained with nanoparticles”, says Jesús Santamaría.

The conclusions of this work suggest a different way: the drug would be supplied to the patient in its inert form and only converted to the toxic form locally, thanks to the catalysis of the nanoparticles that a surgeon would implant in the tumor.
