Researchers organically engineer solar cells using enzymes in papaya fruit

Titanium dioxide (titania) thin films are commonly used in various types of solar cells. The fabrication methods that are currently used to create such titania films require high temperatures, as well as expensive, high-end technologies. Researchers at Delft University of Technology (TU Delft) have now developed a fully organic method to engineer porous titania thin films at relatively low temperatures.

2020 Soft Matter Lectureship awarded to Valeria Garbin

The Royal Society of Chemistry has announced Dr Valeria Garbin as the recipient of the 2020 Soft Matter Lectureship. This annual award was established in 2009 to honour an early-stage career scientist who has made a significant contribution to the soft matter field.

Zigzag DNA

DNA in a cell can normally be compared to spaghetti on one’s plate: a large tangle of strands. To be able to divide DNA neatly between the two daughter cells during cell division, the cell organises this tangle into tightly packed chromosomes. A protein complex called condensin has been known to play a key role in this process, but biologists had no idea exactly how this worked. Until February 2018, when scientists from the Kavli Institute at Delft University of Technology, together with colleagues from EMBL Heidelberg, showed in real time how a condensin protein extrudes a loop in the DNA. Now, follow-up research by the same research groups shows that simple bundling up such loops is by no means the only way condensin packs up DNA. The researchers discovered an entirely new loop structure, which they call the 'Z loop'. They publish this new phenomenon in Nature on 4 March, where they show, for the first time, how condensins mutually interact to fold DNA into a zigzag structure.

Molecular machine tears toxic protein clumps apart

How do cells disentangle proteins that are clumped together? Researchers from AMOLF in Amsterdam and Heidelberg University now show that the molecular chaperone ClpB can forcibly pull on exposed loops of protein chains, and hence extract them from protein clumps. They published their results in Nature today.

New software to better understand conversations between cells

One of the most fascinating and important properties of living cells is their capacity for self-organization. By talking to each other cells can, among other things, determine where they are in relation to each other and whether they need to turn certain genes on or off. Thus, large groups of cells are able to work together and organise into all kinds of tissues. Researchers at Delft University of Technology have now developed software that can predict and visualise conversations between cells on the basis of the molecules involved.

Towards single-cell biopsy with 3D printing

Murali Ghatkesar, assistant professor in the Department of Precision and Microsystems Engineering, has developed a new method through 3D printing that makes it easier, quicker and more efficient to perform single-cell biopsies. It is the first time that 3D printing is being used for the production of micro- and nanofluidic equipment. The results of his research were published in the scientific journal Lab on a Chip this month.
