Bioactive Plastics With Programmable Degradation And Microplastic Elimination

Although the plastic waste crisis has reached a breaking point, current recycling approaches are unable to remediate microplastic pollution. Biodegradable and renewable plastics have shown promise but impact neither microplastic elimination nor complete plastic recycling due to diffusion-limited enzymatic surface erosion and random chain scission. Here it is shown that nanoscopic dispersion of trace enzyme (e.g. lipase) in plastics (e.g. polycaprolactone [PCL]) leads to fully functional plastics with eco-friendly microplastic elimination and programmable degradation. Nanoscopic enzyme encapsulation leads to:continuous degradation to achieve 95% microplastic eliminationa single chain-based degradation mechanism with repolymerizable small molecule by-products via selective chain end scission rather than random chain scissionspatially- and temporally-programmable degradation of melt-processed host matrix due to the dependence of single chain degradation on local lamellae thickness regardless of bulk percent crystallinity formulation of conductive ink for 3-D printing with full recovery of the precious metal filler With recent developments in synthetic biology and genome information, nanoscopically embedding catalytically active enzymes in plastics may lead to an immediate, environmentally friendly and technologically viable solution toward microplastic elimination and material recycling.

Automated Drosophila Maintenance System

Drosophila spp., also known as fruit flies, are widely used in genetic research. Drosophila lines (e.g. flies with a particular mutation) can only be stored as live animals – they cannot be frozen and remain viable. So to maintain the stocks, the live flies are manually transferred from an old vial to a new vial on a regular basis (every 1-2 weeks). Some Drosophila labs maintain hundreds or even thousands of individual lines and so maintenance of these lines can be very time consuming. A UC Santa Cruz Drosophila researcher has developed a simpler and more efficient method of transferring the flies that requires significantly less hands-on work.

Method For Controlling Pests, Spoilage, And/Or Pathogenic Organisms With Radiofrequency Power

Researchers at the University of California, Davis have developed a method to non-invasively inhibit the presence of pests, bacteria, pathogenic or spoilage organisms in agricultural and non-agricultural commodities through the use of continuous radiofrequency (cRF) power.

Non-Living Edible Surrogates For Process Validation Food Processing Plants

Researchers at the University of California, Davis have developed a surface sanitation validation system that utilizes a non-living edible surrogate to potentially help determine food processing efficacy.

Antimicrobial Particle with Affinity for Diverse Bacteria and Bacterial Films

Researchers at the University of California, Davis have developed an antimicrobial particle with the ability to bind bacteria and biofilm.

Fish Tank Effluent Sampling System

Researchers at the University of California, Davis have developed a valve system to collect effluent waste from fish in a closed recirculating aquaponic system (RAS).

Researchers at the University of California, Davis have developed a nondestructive method for identifying raw nuts with concealed damage.

Robotic Plant Care Assistant

Researchers at the University of California, Davis have developed a robotic system can apply signaling to the crops and detect any important needs for the plant.

Gluten Digesting Bacterial Strains

Over the last few years Celiac disease and gluten intolerance has been on the rise. Currently, the only treatment is a gluten free diet, which is very difficult to follow. Cross contamination of gluten free products is common and many food items that seemingly contain no wheat contain gluten-derived products. Here we describe several bacterial strains isolated from humans for their gluten degrading activities. These bacteria may be used to eliminate trace amounts of wheat contaminants from gluten free products or as probiotic therapy.

Scanning for Spoilage of Food Contents in Metallic and Non-Metallic Containers

Researchers have developed a novel method to analyze the contents of closed metal containers to determine contamination in food products.

Novel and Effective Method of Developing Recombinant Proteins

Researchers at the University of California, Davis have developed a novel method to produce and recover high limits of recombinant protein from leaf tissue.

Shrink-Induced, Self-Driven Microfluidic Devices

The addition of novel surface modifications and use of shrink-wrap film to create devices will yield self-driven, shrink-induced microfluidic detection for samples such as bodily fluids. Novel fabrications and surfaces will have a profound impact on the creation of point of care diagnostics.

Superhydrophobic Induced High Numerical Plastic Lenses

The application of novel manufacturing techniques, chemical modifications and alternative materials produces the next generation of lenses. These lenses are inexpensive, contain improved numerical aperture and can be easily manufactured. Overall, these improvements create new applications for miniaturized optical and optical electronic devices.

Method for Increasing Fruiting Body Size and Controlling Seed Release in Commercially Important Plants

Prior to this invention, if increased fruiting body size was desired, multiple generations of plants had to be carefully bred to produce larger fruits with success far from certain. Research at UC San Diego regarding the regulation of flowering genes has uncovered a control point in fruiting body expression. When under the control of a constitutive or regulated promoter for this gene, a transgenic plant with greatly enlarged fruit results. Many kinds of significant commercial crops may now be induced to produce far larger than normal fruiting bodies, apparently, with no loss in fruit quality.

Method for Quantitative Digital Color Imaging of Objects

In many disciplines, quantitative measurements of color are required to evaluate nondestructively the state of an object (e.g., quality of produce). This characterization is typically performed using contact point measurement devices. A limitation of these devices is that multiple measurements are required to characterize an entire object; if multiple objects must be characterized, then this process may be time consuming. Furthermore, these devices interrogate both superficial and deeper structures in the object, and do not possess the ability to discriminate between these structures.
