A LEAD-GLAZED ATRAMENTARIUM DISCOVERED AT APULUM
Recently, in the Southern necropolis of Apulum, an inkwell with lead-glaze was discovered, which had been deposited as funerary inventory in a cremation tomb. Only one other ceramic inkwell from the pottery centre from Micăsasa was known in Dacia.

Site-Selective Biofunctionalization of 3D Microstructures Via Direct Ink Writing. [PDF]
A combination of two‐photon lithography with scanning probe lithography is proposed as a new approach for biofunctionalization of 3D microstructures, with spatially controlled biomolecule distribution. The method utilizes a diverse range of biomolecule inks, including phospholipids, and two different proteins, introducing sub‐1 µm resolution and ...

Rapid Capture of Cancer Extracellular Vesicles by Lipid Patch Microarrays. [PDF]
Extracellular vesicles have great prospects as diagnostic and therapeutic tools. However, their isolation still poses challenges. A novel supported lipid‐membrane‐based platform is introduced for rapid capture, with high specificity and sensitivity, only a small needed analyte volume, and without additional purification steps.

Glucose Oxidase Patterned Meta‐Chemical Surface for Sensing Glucose Using Dip‐Pen Nanolithography
Meta‐chemical surface (MCS) electrode‐based biosensors were developed by using dip‐pen nanolithography (DPN). The DPN enables control over the sizes of and distances between the patterned clusters, which control glucose detection sensitivity and efficiency.

Closed‐loop control is demonstrated for aerosol jet printing by integrating light scattering measurements of the aerosol stream with custom printer software. This system allows quantitative approaches to ink development and fundamental process studies, and supports more consistent and direct control of the deposition rate to support more reliable ...

A Nucleophilic Activity‐Based Probe Enables Profiling of PLP‐Dependent Enzymes
The first activity‐based probe for PLP‐dependent enzymes is reported. The trifunctional probe contains an N‐hydroxyalanine warhead, a linear diazirine, and an alkyne to enable enrichment. The essential protein LysA was identified as the primary target of the probe.

3D Nanolithography by Means of Lipid Ink Spreading Inhibition
Starting from a fluid phase phospholipid ink, 3D patterning is achieved using dip‐pen nanolithography. Pre‐coated Serum Albumin on the surfaces yield unprecedented phospholipid ink spreading inhibition, which enables thickness coordinate control capacity through the writing parameters, namely writing speed and relative humidity. The final metallization

Prussian Blue: Chemistry, Commerce, and Colour in Eighteenth‐Century Paris
This essay reconsiders the story of a pigment. Prussian blue, discovered at the beginning of the eighteenth century, is often described as a revolutionary colour that instantly transformed painters’ palettes and practices. Grounded in a ‘thick description’ of the pigment's history in Paris, this article challenges the legendary account of Prussian blue

Hybrid Mucin‐Vaterite Microspheres for Delivery of Proteolytic Enzyme Chymotrypsin
This study proposes hybrid microspheres made of mucin and mesoporous crystals of vaterite as the carriers for local delivery of proteases. Proteolytic activity is preserved in both pure carbonate and hybrid microspheres, being pH dependent. The modification of carbonate microspheres with mucin i) enhances retention of chymotrypsin on hybrid ...
