Here, we present a protocol to produce high-resolution conductive patterns using electrohydrodynamic (EHD) jet printing. The protocol includes two modes of EHD jet printing: the continuous near-field electrospinning (NFES) and the dot-based drop-on-demand (DOD) EHD printing.

Source: Laboratories of Jonas T. Kaplan and Sarah I. Gimbel—University of Southern California Imagine the sound of a bell ringing. What is happening in the brain when we conjure up a sound like this in the "mind's ear?" There is growing evidence that the brain uses the same mechanisms for imagination that it uses for perception.1 For example, when imagining visual images, the visual cortex becomes activated, and when imagining sounds, the auditory cortex is engaged. However, to what extent are...

We report that the diffraction limit of conventional optical lithography can be overcome by exploiting the transitions of organic photochromic derivatives induced by their photoisomerization at low light intensities.1-3 This paper outlines our fabrication technique and two locking mechanisms, namely: dissolution of one photoisomer and electrochemical oxidation.

Here we describe a simple method for patterning oxide-free silicon and germanium with reactive organic monolayers and demonstrate functionalization of the patterned substrates with small molecules and proteins. The approach completely protects surfaces from chemical oxidation, provides precise control over feature morphology, and provides ready access to chemically discriminated patterns.
FAQs
The central design variables are feature size, spacing, and composition. Changing them alters how patterned elements are distributed and therefore how a constructed interface or tissue-like architecture is organized. In bioengineering, controlling these variables helps connect physical arrangement with function, allowing researchers to examine how precisely positioned materials, cells, or biochemical signals contribute to biological structure.
Different patterning routes control placement in different ways. Spatially controlled deposition adds material where needed, transfer moves a prepared pattern, and removal creates features by taking material away. Patterned templates, focused energy, or automated fabrication systems can guide these operations. Selecting among these mechanisms determines how researchers establish the intended microscale or nanoscale geometry.
Spatial cues provide organized locations for materials, cells, or biochemical signals, giving biological systems a controlled arrangement to respond to. In bioengineering, these arrangements help researchers investigate how position and neighboring features influence cell behavior and tissue formation. They also support the creation of tissue-like architectures and interfaces that mimic aspects of the native biological environment.
A practical workflow begins by choosing whether the construct will be formed through deposition, transfer, or removal, then using a template, focused energy, or automated fabrication system to guide placement. Researchers can regulate feature size, spacing, and composition during this process, producing organized arrangements of materials, cells, or biochemical signals for a defined bioengineering purpose.
The technique supports several bioengineering applications, including biosensor development, tissue engineering, drug screening, and studies of biological interfaces. In each setting, controlled spatial organization can help create functional architectures or test how cells respond to defined environmental features. Its value comes from linking microscale or nanoscale arrangement with measurable biological structure and function.
Patterned constructs can provide organized platforms for examining how spatially positioned materials, cells, or biochemical signals affect biological behavior. They can also support the formation of tissue-like architectures and interfaces that reproduce selected aspects of native environments. These outcomes help connect fabrication parameters with cell behavior, tissue formation, sensing functions, or drug-screening studies.
