This study presents core‐shell Au‐Ag NPs and a novel molecularly imprinted polymer (MIP)‐based material targeting L1CAM. Thionine is used as a monomer to create the MIP on a carbon screen‐printed electrode. Functionalized Au‐AgNCs with Raman reporter 4‐mercaptobenzoic acid and anti‐L1CAM enable selective detection via surface‐enhanced Raman scattering ...

Hybrid DNA Origami – Graphene Platform for Electrically‐Gated Nanoscale Motion
A hybrid DNA origami‐graphene architecture is employed in a nearfield sensing device for optical distance assessment in biosensors and biorecognition purposes. Using Fluorescence Lifetime Imaging Microscopy (FLIM), a nearfield quenching model is verified and test the device response under several electrostatic gating conditions, which leads to changes ...

AgNPs cause significant damage upon entering the lysosomes of human fibroblasts, resulting in lysosomal transport disorders and the occurrence of perinuclear clustering (LPC) of lysosomes by promoting apoptosis that is accompanied by a reduction in the expression levels of ESCRT III and Kinesin 1 proteins.

Flexographic Printed Flexible Thermochromic Stickers for Smart Sensing Applications
Thermochromic complexes of 1‐butyl‐3‐methylimidazolium chloride and 4‐chloronickelate are synthesized and incorporated in hydroxypropyl cellulose‐based water inks. Films with 40 wt.% thermochromic complexes and three layers are flexographic printed on polypropylene tags in a process compatible with roll‐to‐roll manufacturing. After encapsulation with a

Polyamide 12 powder nanoadditivated with laser‐synthesized silver nanoparticles is deposited and sintered on polymer parts via EPA‐PBF‐LB/P. The thin surface coating (140 µm) inhibits E. coli and S. aureus bacteria growth and significantly increases the UV light absorption, whereas the mechanical and thermal properties remain unchanged due to minimal ...

In chiral and polar metal‐halide single crystals or thin films, the orientation of the main optical axis normal to incident light allows an easy characterization of the chiroptical properties (circular dichroism and circularly polarized luminescence) without artifacts or macroscopic interferences, despite the highly anisotropic nature in this family of
