Fabricating materials from naturally occurring proteins that are inherently biocompatible enables the resulting material to be easily integrated with many downstream applications, ranging from batteries to transistors. In addition, protein-based materials are also advantageous because they can be physically tuned and specifically functionalized. Inventors have developed protein-based material from structural proteins such as reflectins found in cephalopods, a molluscan class that includes cuttlefish, squid, and octopus. In a space dominated by artificial, man-made proton-conducting materials, this material is derived from naturally occurring proteins.

Superhydrophobic surfaces that repel liquid have found a multitude of applications due to their self-cleaning and antibacterial effects, but are often highly surface selective and difficult to produce. Researchers at UCI have developed a new method to reliably mass produce universal superhydrophobic surfaces in a simpler and more cost effective manner.

Medical devices are susceptible to contamination by harmful microbes, such as bacteria and fungi, which form biofilms on device surfaces. These biofilms are often resistant to antibiotics and other current treatments, resulting in over 2 million people per year suffering from diseases related to these contaminating microbes. Death rates for many of these diseases are high, often exceeding 50%. Researchers at UCI have developed a novel anti-bacterial and anti-fungal biocomposite that incorporates a nanopillared surface structure that can be applied as a coating to medical devices.

Individual layers are single- or few-atoms thick and exhibit unique mechanical, electrical, and optical properties, and are thus expected to see widespread adoption in devices across a range of fields such as optical, electronic, sensing, and biomedical devices.  Graphene and transition metal dichalcogenides offer desirable properties as few-layer or monolayer film. Accessing the monolayer form in a repeatable fashion, as part of a predictable and high-yield manufacturing process is critical to realizing the many potential applications of two-dimensional materials at scale. In order to fabricate devices made from few- or monolayer materials, layer(s) of material of specified size and shape, arranged in a pre-determined pattern, must be deposited on a desired substrate and conventional transfer methods include pressure-sensitive adhesives and other viscoelastic polymers and require applied pressure to adhere to their target which can cause out-of-plane deformations and problems with isolating and transferring the patterned few- or monolayer material. Deep etching has similar drawbacks.   UC Berkeley researchers have discovered methods and compositions that enable the transfer medium to adhere strictly to patterned regions, allowing the transfer to remove only patterned material and leave behind unpatterned bulk. This method involves the creation of an intermediate layer between the source material and the transfer medium. Because this layer must strictly cover patterned material, it serves as an etch mask for isolating few-layer material in the desired pattern. Any material which is microns-thick, patternable at the desired lateral pattern scale (likely micron-scale), and subsequently removable would make a suitable intermediate layer.
