In article number 1800117, Lihong Li, Yanlin Song, and co‐workers prepare a 1D assembly array of single particle resolution inspired by the magnetosome structure via an inkjet printing method under magnetic guiding. In the confined printed droplet, particles are attracted “tip‐to‐tip” into 1D assembly, which pins on the substrate with a low receding angle. The 1D array can be used for magnetic field...
Magnetosensing is a ubiquitous ability for many organism species in nature. 1D assembly, especially that arranged in single‐particle‐resolution regulation, is able to sense the direction of magnetic field depending on the enhanced dipolar interaction in the linear orientation. Inspired by the magnetosome structure in magnetotactic bacteria, a 1D assembly array of single particle resolution with controlled...
Inkjet printing (IJP) is an old but still vivifying technique for flexible and cost‐effective printing of various kinds of functional inks. Normally, IJP can only work in gaseous environments. Here, it is shown that traditional piezoelectric IJP can be performed in liquid environments with a totally different droplet dispensing and manipulating mechanism. With the same piezoelectric nozzle, the volume...
Despite their specific methodologies, all current noncontact printing techniques such as inkjet printing (IJP), involve the break‐up of a liquid meniscus during the separation of the ink droplet from the bulk ink reservoir. Often, the break‐up of a liquid meniscus results in the formation of one or more satellite droplet whose volumes are several orders of magnitude smaller than the primary droplet...
The requirement of nontoxic and versatile manufacturing frameworks for biologically relevant applications has imposed significant constraints on the choice of functional materials and the complementary fabrication tools. In this context, silk is actively studied, thanks to its mechanical robustness, biocompatibility, wide availability, aqueous processing conditions, and ease of functionalization....
In article number 1802953, Tiger H. Tao and co‐workers report a silk‐based water lithography technique. This work introduces a wafer‐scale, all‐water‐based, chemical‐free, biopatterning method that allows for rapid prototyping of biologically functional devices and interfaces in an extremely fast fashion, and importantly, in ambient conditions, on both planar and curved surfaces.
