New mechanism to transfer chirality between molecules in the nanoscale field

EurekAlert! – 27 April 2021

“Our study provides a new fundamental insight of the mechanisms underlying the chirality transfer, demonstrating that this intrinsic property of living matter is based on the interaction of physical and chemical restrictions acting synergistically across multiple length-scales,” concludes Prof. Josep Puigmartí-Luis.


Research reveals a new mechanism to transfer chirality between molecules in the nanoscale field

Phys.org – 26 April 2022

“For this to work, we need to understand and characterize the transport phenomena occurring within the reactor, namely, the fluid dynamics and the mass transport, which determine the formation of reagent concentration fronts and the positioning of the reaction zone in regions of specific chirality,” notes Prof. Josep Puigmartí-Luis.


New mechanism to transfer chirality between molecules in the nanoscale field

News U. de Barcelona – April 2022

If we compare the right to the left hand, we can see these are specular images —that is, like symmetrical shapes reflected in a mirror— and they cannot superimpose on each other. This property is chirality, a feature of the matter that plays with the symmetry of biological structures at different scales, from the DNA molecule to the tissues of the heart muscle.


Simulated microgravity system created to experiment with materials

EurekAlert! – 21 September 2021

Crystallization studies conducted in space laboratories, which are costly and unaffordable for most research laboratories, showed the valuable effects of microgravity during the crystal growth process and the morphogenesis of materials. Now, a research study led by a scientific team of the University of Barcelona, has created an easy and efficient method to achieve experimentation conditions of microgravity on Earth that simulate those in space.


Variable-stiffness catheter could increase the safety of robotic eye surgery

Physics World – 12 Agust 2021

A surgical catheter that can change its rigidity as needed during operations has been developed by researchers from Switzerland and Spain. The tool – the core of which is built from a tailored phase-change alloy – could improve the safety of minimally-invasive ophthalmic surgeries.

A simulated microgravity system has been created to experiment with materials

Noticiasdelaciencia – 30 July 2021

Para conseguir estas condiciones de microgravedad simulada, se ha recurrido al uso de dispositivos microfluídicos personalizados para fabricar estructuras moleculares de cristales porosos en dos dimensiones. Según explica el Prof. Josep Puigmartí Luis, investigador ICREA en el Departamento de Química Física y miembro del Instituto de Química Teórica y Computacional (IQTCUB) de la UB, «se ha podido confirmar que los experimentos bajo estas condiciones de microgravedad simulada tienen efectos sin precedentes en la orientación, la compacidad y la generación de materiales 2D cristalinos y porosos».

Phys.org – 29 July 2021

“The spatio-temporal control in the growth of this material obtained with the simulated microgravity conditions is unprecedented in the scientific literature. The microfluidic device has allowed us to develop centimeter-long thin layers and study the previously undescribed electronic properties of the material”

Simulated Microgravity for Chemistry and Materials Synthesis

Exterior.cat – 19 juliol 2021

El professor d’investigació d’ICREA, Josep Puigmartí (Artés, 1978) acaba de publicar un article a la revista Advanced Materials sobre la creació de materials 2D emprant condicions que simulen la microgravetat que s’experimenta a l’estació espacial internacional, un procés diferent del que s’utilitzava fins ara.

Fugint de les mescles que creen turbulències i corrents de convecció i apostant per un mesclat controlat al laboratori, l’equip que encapçala el bagenc a la Universitat de Barcelona (UB) posa en valor els avantatges que es podrien obtenir en cas de dirigir les investigacions en el camp de la química i de la síntesi de materials emprant aquestes condicions.

Micro-Nanorobots to clear blood clots

Nanowerk – 25 May 2021

Professor Salvador Pané and Professor Josep Puigmartí-Luis, researchers in the ANGIE project, hope targeted drug delivery will allow doctors to treat a greater number of stroke patients more effectively. Ischaemic strokes, which occur when blood clots cut off the flow of blood in the brain, are a leading cause of death in the European Union, with more than 1.1 million people suffering strokes each year.

Nanorobots could target cancers and clear blood clots

Horizon Magazine – 25 May 2021

“If treatments could be directed to the location in a vein or artery where a clot is occurring, they could be cleared far more effectively.

In ANGIE the researchers are creating tiny nanorobots that can do just this and deliver the drug directly onto the clot.

‘They really are robots – you’re able to control them, accelerate, stop, move them in all three directions,’ said Prof. Puigmartí-Luis, a chemist at the University of Barcelona in Spain. In principle, they can roll, corkscrew, and tumble.”

What’s sweeter than a robot made from candy?

Advanced Science News – 19 Nov 2020

“A current trend in small-scale robotics consists of developing biodegradable platforms that do not require retrieval after their tasks have been accomplished” said Puigmartí-Luis. “[Our] CANDYBOTS degrade very quick in water, which makes them attractive for applications where dissolution of the device should take place very rapidly.”

Magnetically propelled MOFBOTs perform microrobotic drug delivery

Nanowerk – May 20, 2019

“While initial efforts have been made to produce mobile MOF-based small-scale machines, the locomotion features of most of these systems lack the level of sophistication of current state-of-the-art micro- and nanoswimmers,” Dr. Josep Puigmartí-Luis from ETH Zurich, tells Nanowerk. “For example, the controlled directionality of chemically propelled MOF crystals has yet to be addressed.”
