Abstract The field of bioelectronics with the aim to contact cells, cell clusters, biological tissues and organoids has become a vast enterprise. Currently, it is mainly relying on classical micro‐ nanofabrication methods build devices systems. Very recently highly pushed by development novel printable organic, inorganic biomaterials as well advanced digital printing technologies such laser inkjet employed in this endeavor. Recent advantages alternative additive manufacturing 3D enable...
Abstract While patterning 2D metallic nanostructures are well established through different techniques, 3D printing still constitutes a major bottleneck on the way to device miniaturization. In this work fluid phase phospholipid ink is used as building block for structuring with dip‐pen nanolithography. Following bioinspired approach that relies ink‐spreading inhibition, two processes presented build and structures. Serum albumin, widely protein an innate capability bind lipids, key in both...
Abstract The characterization of phospholipid membrane permeability for small molecules is crucial many applications in drug discovery and biomedical research general. Here, chemosensor‐laden vesicles offer an attractive platform assays. In this work, the stability immobilized chemosensor‐filled explored on anti‐fouling polymer brush surfaces potential use monitoring molecule permeability. study focuses development a method immobilizing sensor‐loaded into arbitrary patterns characterizing...
Vesicle Immobilization Vesicles filled with chemosensors are immobilized into regular arrays on a polymer brush antifouling surface. Analytes entering the vesicle can turn off chemosensor fluorescence. In article 2400200, Michael Hirtz and co-workers investigate stability of these systems their potential for membrane permeability assays.
Abstract Two‐photon lithography has revolutionized multi‐photon 3D laser printing, enabling precise fabrication of micro‐ and nanoscale structures. Despite many advancements, challenges still persist, particularly in biofunctionalization microstructures. This study introduces a novel approach combining two‐photon with scanning probe for post‐functionalization microstructures overcoming limitations achieving spatially controlled biomolecule distribution. The method utilizes diverse range...
Lipid Ink Spreading Inhibition In article number 2205590, Eider Berganza, Michael Hirtz, and co-workers utilize dip-pen nanolithography to print lipid patches layer-by-layer forming 3D structures on a surface coated with serum albumin stabilizing the structures. The molecules transfer from probe substrate through water meniscus. To further improve their stability, lipid-structures get covered few nanometers of gold physical vapor deposition.
