Electrospinning of polymer material has gained a lot of interest in the past decades. Various methods of electrospinning have been applied for different applications, from needle electrospinning to needleless electrospinning. A relatively new variation of electrospinning, namely near-field electrospinning, has been used to generate well-defined patterns.

This study investigates the presence of Legionella in the hot water systems from 49 primary schools across two municipalities in the Danish capital region. Water samples were collected from taps in each school, and both first-flush and stabile temperature samples were analysed for Legionella contents.

- - Serine hydrolases, while useful for recycling PET plastics, have limitations due to their 3D structure, which restricts their effective application conditions.
- - Researchers designed a 25 amino acid thermostable peptide called HSH-25 that mimics the catalytic features of serine hydrolases and showed potential for depolymerizing PET.
- - The study confirmed that HSH-25 exhibits enzyme-like activity in a specific pH range and was effective in degrading PET substrates, with results visualized through atomic force microscopy.
Enzymatic degradation of plastics is currently limited to the use of engineered natural enzymes. As of yet, all engineering approaches applied to plastic degrading enzymes retain the natural $\alpha /\beta $-fold. While mutations can be used to increase thermostability, an inherent maximum likely exists for the $\alpha /\beta $-fold.

- State-of-the-art clinical detection methods use complex immunoassays that need special equipment and trained staff, making them less practical for Point-of-Care (PoC) settings where simplicity, portability, and affordability are crucial.
- Small, durable electrochemical biosensors can effectively analyze biomarkers in biological fluids for PoC use, with key improvements needed in sensing surfaces, immobilization methods, and reporter systems.
- A study found that an adapted electrochemical immunosensor effectively detected Neutrophil Gelatinase-Associated Lipocalin (NGAL) in urine, achieving a limit of detection at 1 ng/mL and demonstrating reliability for use with screen-printed or thin-film gold electrodes.
