From nano at chalmers.se Mon Nov 11 08:57:25 2024 From: nano at chalmers.se (Nano) Date: Mon, 11 Nov 2024 07:57:25 +0000 Subject: [Info.aoa-nano] Join the SmallTalks about Nanoscience today! Message-ID: Join us today, Monday 11 November at 15.00h for our SmallTalks [about Nanoscience] You are welcome to join us in lecture hall Kollektorn, MC2 with fika or on zoom. Our speaker is Robin Rydbergh, Project Assistant, Chemistry and Biochemistry, Chemistry and Chemical Engineering. The seminar is titled ??Nanoscale Mass Spectrometry Imaging of Pollution Particles on Cell epithelia?. The seminar is divided into two parts, where the first part consists of a pure overview of the field and is held on a generally accessible level (10 min). The second part will be more technical (15-20 minutes). Abstract Air pollution is a major environmental risk for health, with about 99% of the world?s population breathing polluted air, causing 6.8 million early deaths each year (World Health Organization, 2022). In this research project we have looked at how tiny (nano scale) particles from braking trains affect human cells. We created these particles and exposed human cells to them and using an advanced mass spectrometry imaging method, we could see how these particles interact with cell structures. Our new method shows that we could use this approach to study how pollution affects cells, helping future research on how these particles might be toxic. This presentation will highlight the need to understand how pollutants interact with us humans to find ways to better reduce air pollution's health risks.

The seminar is titled ??From the Covid vaccine to lactose free milk: How we can use lipid nanoparticles as biomolecule delivery vehicles?. The seminar is divided into two parts, where the first part consists of a pure overview of the field and is held on a generally accessible level (10 min). The second part will be more technical (15-20 minutes). Abstract One of the first things you are taught in chemistry at school is that water and oil don?t mix. Some molecules, however, have parts that like water (hydrophilic) and parts that like oil (hydrophobic or ?water hating?), such as the lipids which make up cell membranes in your body. These lipids are called amphiphilic lipids and are composed of a hydrophilic head group and a hydrophobic hydrocarbon tail. When you mix amphiphilic lipids with water, they can form a wide variety of structures, from simple spheres to a 2D sheet (bilayer) and intricate 3D channel networks, depending on the lipid shape and its environment (e.g. temperature and pH). This means that we can make complicated structures with properties, which can be tuned for different applications. One common application in both the food and pharmaceutical industries for these lipid structures is the encapsulation of biomolecules, such as proteins and nucleic acids (like DNA and RNA). As these biomolecules can be quite sensitive, encapsulation can help to keep them more stable. Here I will present two examples, where we have studied biomolecule encapsulation with two different systems: 1) different types of RNA and DNA in a Covid vaccine style formulation and 2) proteins used in the food industry to make different dairy products.
