Effective insertion of nanowires into cells is critical for monitoring subcellular activities, bio‐electrical devices, and photosynthetic bio‐energy harvesting. On page 1446, W. Ryu, J. Moon and co‐workers demonstrate the possibility of direct insertion of nanowires into living algal cells using inkjet printing technology. While most cell printing technologies aim to print cells on a flat substrate,...
Effective insertion of vertically aligned nanowires (NWs) into cells is critical for bioelectrical and biochemical devices, biological delivery systems, and photosynthetic bioenergy harvesting. However, accurate insertion of NWs into living cells using scalable processes has not yet been achieved. Here, NWs are inserted into living Chlamydomonas reinhardtii cells (Chlamy cells) via inkjet printing...
Perovskite single‐crystalline microplate arrays are directly achieved in large scale by inkjet printing, which present high performance lasing property with quality factors up to 863 and RGB (red‐green‐blue) emission. This facile, nonlithographic method makes its promising applications on multi‐integrated coherent light sources and other high‐performance integrated optoelectronic applications.
Perovskite single‐crystalline microplate arrays are fabricated on a large scale via inkjet printing technology by Mingzhu Li, Yanlin Song, and co‐workers in article number 1603217. By modulating the inkjet droplet volume and the ink composition, a tunable single/multiple mode laser with high quality factors up to 863 and three primary‐color microplates are achieved. This work makes a great step toward...
Improved thin‐film microbatteries are needed to provide appropriate energy‐storage options to power the multitude of devices that will bring the proposed “Internet of Things” network to fruition (e.g., active radio‐frequency identification tags and microcontrollers for wearable and implantable devices). Although impressive efforts have been made to improve the energy density of 3D microbatteries,...
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.
Diamond is a highly desirable material for state‐of‐the‐art micro‐electromechanical (MEMS) devices, radio‐frequency filters and mass sensors, due to its extreme properties and robustness. However, the fabrication/integration of diamond structures into Si‐based components remain costly and complex. In this work, a lithography‐free, low‐cost method is introduced to fabricate diamond‐based micro‐resonators:...
Quantum dots light‐emitting diodes (QLEDs) have attracted much interest owing to their compatibility with low‐cost inkjet printing technology and potential for use in large‐area full‐color pixelated display. However, it is challenging to fabricate high efficiency inkjet‐printed QLEDs because of the coffee ring effects and inferior resistance to solvents from the underlying polymer film during the...

The inkjet‐printed CBP‐V film is smooth and flat. After thermal curing, an extremely dense and crosslinked solvent resistant film is formed. The function of this film for...

The achieved optical detection of E. coli O157:H7 in real complex samples represents the lowest limit of detection reported to date.
The increasing incidence of infectious outbreaks from contaminated food and water supply continues imposing a global burden for food safety, creating a market demand for on‐site, disposable, easy‐to‐use, and cost‐efficient devices. Despite of the rapid growth of biosensors field and the generation of breakthrough technologies, more than 80% of the platforms developed at lab‐scale never will get to...
Flexible planar micro‐supercapacitors (MSCs) with unique loose and porous nanofiber‐like electrode structures are fabricated by combining electrochemical deposition with inkjet printing.

Nanoparticle‐based voluminous 3D networks with low densities are a unique class of materials and are commonly known as aerogels. Due to the high surface‐to‐volume ratio, aerogels and xerogels might be suitable materials for applications in different fields, e.g. photocatalysis, catalysis, or sensing. One major difficulty in the handling of nanoparticle‐based aerogels and xerogels is the defined patterning...
Cellular membranes are composed of a variety of lipids in different amounts and proportions, and alterations of them are usually closely related to various diseases. To reveal the intercellular heterogeneity of the lipid variation, an integrated microfluidic system is designed, which consists of droplet‐based inkjet printing, dielectrophoretic electrodes, and de‐emulsification interface to achieve...
