2023
The fabrication of BioMEM devices is often done using a microfabrication technique called photolithography. This widely used method utilizes light to transfer a pattern onto a silicon wafer, and provides the basis for the fabrication of many types of BioMEM devices. This video presents the photolithography technique, shows how the process is performed in the cleanroom, and introduces some applications of the process.

Social Traps

Social traps are negative situations where people get caught in a direction or relationship that later proves to be unpleasant, with no easy way to back out of or avoid. The concept was orignally introduced by John Platt who applied psychology to Garrett Hardin's "Tragedy of the Commons", where in New England herd owners could let their cattle graze in the common ground. This situation seems like a good idea, but an individual could have an advantage. If they owned more cows, the larger...

In this protocol, we demonstrate the fabrication of a microactuator array of vertically displaced posts on which the technology is based, and how this base technology can be modified to conduct high-throughput mechanically dynamic cell culture in both two-dimensional and three-dimensional culture paradigms.
FAQs
Radio-frequency and static voltages work together to produce the confining electric fields. Their combined effect creates a stable three-dimensional potential above the substrate, rather than restricting motion only along the chip surface. This division of electrical control is central to maintaining trapped ions near the device while allowing the electrode array to manipulate their position.
A three-dimensional potential gives trapped ions a stable region of confinement above the substrate, where they can remain controlled without being embedded in the device. Because the potential is generated by integrated electrodes, the same chip can support confinement and controlled changes in ion position. This arrangement makes surface-based manipulation practical for compact engineered systems.
Electrode arrays allow the applied voltages to shape the electric fields along the chip and change the resulting trapping conditions. By controlling these fields, researchers can move ions, divide groups of trapped ions, or bring them back together. These operations provide the physical control needed for organizing ions during experiments and for implementing scalable processor architectures.
Lithographic patterning integrates the electrodes directly onto a substrate, producing compact structures with organized electrode arrays. This architecture supports multiple forms of ion control on a chip, including transport, splitting, and merging. Such capabilities are especially relevant to scalable quantum information processors, where controlled manipulation of trapped ions must be incorporated into increasingly complex device layouts.
The devices are produced by lithographically patterning electrode structures and integrating those electrodes on a substrate. The fabrication approach creates a compact chip-based platform in which applied radio-frequency and static voltages generate the trapping fields. Engineering attention therefore centers on combining patterned electrode arrays with electrical control suitable for manipulating ions above the substrate.
These devices support several research areas that require controlled charged particles. Their applications include scalable quantum information processors, precision spectroscopy, mass spectrometry, and studies of ion-matter interactions. The same underlying ability to confine and manipulate ions can therefore serve computing, measurement, analytical, and fundamental interaction studies without being limited to a single experimental purpose.
Engineering determines how lithographically patterned electrodes are integrated into a compact substrate, while applied voltages establish the fields needed for ion control. That connection enables experiments in which ions can be confined, transported, split, or merged in a deliberately designed device. It also links chip fabrication to spectroscopy, mass analysis, quantum information, and ion-matter research.
