Traceless Photopolymerization with Non‐Pulsed Red Light Enables 3D‐Printable Cell‐Laden Hydrogels

Advanced Materials, Volume 37, Issue 30, July 29, 2025.
The paper presents a red‐light‐induced polymerization process, initiated by the FDA‐approved dye methylene blue and the cytocompatible co‐initiator triethanolamine, for fabricating hydrogels. This photopolymerization process is oxygen‐tolerant, cytocompatible, and, most importantly, leaves no color traces, resulting in completely transparent scaffolds.

Elucidating the Supramolecular Interaction of Positively Supercharged Fluorescent Protein with Anionic Phthalocyanines

Advanced Biology, Volume 9, Issue 5, May 2025.
Positively supercharged mGreenLatern protein is self‐assembled electrostatically with negatively charged zinc phthalocyanines to yield bio‐based photoactive materials in aqueous media. The addition of phthalocyanines results in the formation of large complexes fully quenching of the protein fluorescence. The results indicate an energy transfer from the

A Systematic Study of Staphylococcus aureus Biofilm Formation on Thiol‐Ene Polymers: Toward the Development of Microfluidic Bacterial Biofilm Models

Advanced Materials Interfaces, Volume 12, Issue 10, May 19, 2025.
This work presents a systematic characterization of an emerging polymer platform, off‐stoichiometry thiol‐ene, in terms of its ability to support the formation, growth, and metabolic activity of Staphylococcus aureus biofilms. The findings indicate that thiol‐enes promote S.

Pedagogers tankar om naturvetenskap i förskolan

Venue, 2015
Hur arbetar pedagoger på fältet med naturvetenskap efter den reviderade läroplanen för förskolan? Vad gör de för att ta vara på barnens nyfikenhet i naturkunskapsfrågor? Vilka möjligheter och hinder finns? Vi frågade åtta pedagoger på fyra olika förskolor för att söka svaren på dessa frågor.

Photocleavage and Photophysical Properties of Amine Releasing BODIPY Derivatives

Chemistry – A European Journal, Volume 31, Issue 24, April 25, 2025.
This paper introduces the synthesis, structural studies, photophysical properties, and photocleavage studies of three novel green light cleavable boron dipyrromethene (BODIPY) derivatives with varying sizes of aromatic terminal groups. All BODIPY derivatives have similar spectroscopical properties. Photocleavage studies in different conditions revealed

Folding of mRNA‐DNA Origami for Controlled Translation and Viral Vector Packaging

Advanced Materials, Volume 37, Issue 15, April 16, 2025.
The packaging of mRNA into a compact, predefined shape can impact cellular delivery. This study presents a first set of design rules for the efficient folding of mRNA‐DNA origami structures, while preserving its initial translation functionality, which is demonstrated extracellularly as well as in vitro by using virus capsid proteins for packaging and ...

Redox‐Active Bisphosphonate‐Based Viologens as Negolytes for Aqueous Organic Flow Batteries

Chemistry – A European Journal, Volume 31, Issue 16, March 17, 2025.
Bisphosphonate‐substituted viologens (BBPE‐Vi and MBPE‐Vi) exhibit high solubility (1.45 M) and stability (0.009% capacity decay per cycle), making them effective for AOFBs. The bulky, negatively charged bisphosphonate groups reduce degradation through bimolecular side reactions, while their electron‐rich character in the deprotonated state effectively

Naturvetenskap i förskolan nya perspektiv

, 2023
Elefanter dricker 200 liter vatten om dagen. Dinosaurien Plateosaurus var växtätare. Det finns inget liv på månen. Barn möter många påståenden av den här typen i böcker, TV-program och filmer riktade till barn.
