Revolutionizing Biology with Designed Nanopores

Nanopores play a crucial role in sequencing nucleic acids like DNA and RNA , as well as peptides . These tiny transmembrane - barrel pores have the potential to revolutionize sensing and sequencing applications by miniaturizing them into portable USB - sized devices and point - of - care technologies . However , current methods of engineering nanopores are limited to naturally occurring proteins , which may not be the most ideal starting points for sensor development due to their complex requirements.

Designing Nanopores from Scratch

A recent collaboration between the VIB - VUB Center for Structural Biology in Belgium and the University of Washington School of Medicine in Seattle has introduced a groundbreaking approach to designing transmembrane - barrel pores from scratch . By utilizing computational design , researchers have been able to create stable nanopore channels with customizable shapes , sizes , and conductance . This innovative method allows for the development of nanopores with distinct conductances correlated with their pore diameters , making them suitable for various research and industrial applications.

The team 's work , published in Science under the title " Sculpting conducting nanopore size and shape through de novo protein design , " marks a significant advancement in the field of analytical biology . The ability to design nanopores with a high success rate and reproducible conductance has opened up new possibilities for single - molecule analytics , demonstrating the potential to sense a wide range of metabolites , proteins , and small molecules using portable devices equipped with custom nanopores.

Unleashing the Potential of Protein Design

One of the key figures behind this groundbreaking research , Dr. David Baker from the University of Washington School of Medicine , emphasized the power of protein design in creating tailored functions from first principles . By moving away from repurposing biomolecules from nature , researchers can now craft nanopores with specific properties and functionalities , paving the way for a new era of biological sensing and sequencing technologies.

Dr. Anastassia Vorobieva , a group leader at the VIB - VUB Center for Structural Biology , highlighted the success of the team 's efforts in designing stable nanopores with reproducible conductance . This achievement , once deemed impossible by many due to the complexity of protein folding , opens up endless possibilities for creating novel nanopores with desired characteristics.

In conclusion , the innovative approach to designing nanopores from scratch represents a significant leap forward in the field of biology . With the potential to create an unlimited number of new nanopores tailored to specific applications , this research sets the stage for a future where portable devices equipped with custom nanopores can revolutionize the way we analyze and detect biological molecules.
