Cell-e-brities series
Hello everybody, I welcome you all to our Cell-e-brities series, where we get to know the amazing personalities in Biology, their different roles, and their contributions to this planet. I am delighted to host ‘Proteins’ on my chat show in this series. Indeed, it is impossible to know everything about them in one episode, so today, ‘Proteins’ will talk about their recent roles as ‘Protein Nanofibrils.’
👩🔬Van: Welcome, Proteins. We know you are versatile and dynamic, but how did you prepare yourself for the role of alleviating water scarcity?
Proteins: Well, thank you. Recently, we have been designed as Nanofibrils (we are popular as amyloid nanofibrils) with several interactive binding sites that enhance our adsorption capacity towards water contaminants. These nanofibrils are incredibly stable and have a large surface area, which makes them great for binding and trapping contaminants from water.
👩🔬Van: That’s fascinating! When we hear “amyloid fibrils,” most of us think of diseases, but it’s interesting that their same structural features, the tightly packed β-sheet architecture can actually be used for something good. So tell us, how do you make use of those properties in real purification systems?
Proteins: Oh yes! As nanofibrils, we’re essentially supramolecular polymers made up of tightly packed β-sheet structures arranged in what scientists call a cross-β pattern. Our sequence of alternating hydrophilic and hydrophobic amino acids gives us that characteristic twisted shape. We’re quite small, about 5 to 10 nanometers in diameter, yet we can stretch up to several micrometers in length. Our stability comes from a dense network of hydrogen bonds and van der Waals forces that hold us together, giving us remarkable mechanical strength and resistance to enzymatic degradation. We also carry unique traits like chirality, polarity, and surface charge, which make us highly interactive and versatile in applications such as water purification and nanotechnology.
👩🔬Van: It’s been wonderful learning about your structure and sustainability role. Before we close, is there any message you’d like to share with people, something you want us to understand about your role or potential?
Proteins: We’re glad that as nanofibrils, our design aligns with the three pillars of sustainability , planet, people, and profit. Our role goes beyond science; it’s about creating solutions that are eco-friendly, economically viable, and beneficial to society. We hope more people start seeing sustainability not as a choice, but as a shared responsibility.
Protein nanofibrils are emerging scaffolds and dynamic building blocks for designing smart functional materials for tissue engineering, biomedicine, materials science, nanotechnology, renewable energy, and environmental applications. If you are curious to know more you can check this out.
Thank you, everybody. Stay safe, stay happy.
