Soft-tissue injuries and organ transplantation are common in modern combat scenarios. Organs and tissues harvested for transplantation need to be preserved during transport, which can be very difficult. Micro and nanobubbles (MNBs) offer a new technology that could supply oxygenation to such tissues prior to transplantation, thus affording better recovery and survival of patients. Described here is a novel device capable of producing MNB solutions that can be used to preserve viability and function of such organs/tissue. Additionally, these solutions may be used with negative pressure wound therapy to heal soft-tissue wounds.

Nanostructured materials are a category of materials comprised of nanometer-scale crystals which exhibit order of magnitude higher strength when compared to their traditional counterparts with larger crystal sizes. The application of nanostructured materials has been limited due to seemingly inherent low ductility and high-temperature instability.

Semiconductor materials are fundamental materials in all modern electronic devices. Continuous demand for faster and more energy-efficient electronics is pushing miniaturization and scaling to unprecedented levels. Controlled and uniform doping of semiconductor materials with atomic accuracy is critical to materials and device performance. In particular, junction depth and dopant concentration need to be tightly controlled to minimize contact resistance, as well as variability effects due to random dopant fluctuations in the channel. Conventional doping methods such as ion implantation is imprecise and can have large variability effect. Moreover, energetic introduction of dopant species will often cause crystal damage, leading to incompatibility with nanostructured-materials and further performance degradation. To address these problems, researchers at the University of California, Berkeley, have experimented with an alternative approach to a wafer-scale surface doping technique first developed at the UC Berkeley in 2007. The team has demonstrated a controlled approach for monolayer doping (MLD) in which gas phase dopant-containing molecules form low-variability, self-assembled monolayers (SAM) on target semiconductor surfaces.

Heart failure following a myocardial infarction (MI) continues to be one of the leading causes of death. Immediately after MI, there is an initial inflammatory response with cardiomyocyte death and degradation of the extracellular matrix. This results in negative left ventricular (LV) remodeling leading to wall thinning, LV dilation, and depressed cardiac function. Several experimental approaches have been examined to inhibit this negative remodeling process. One promising direction is the use of injectable biomaterials, which can be used as stand-alone scaffolds to encourage endogenous repair or for delivering therapeutics such as cells, growth factors, or small molecules. Early intervention of MI has the potential to slow or inhibit the progression of negative LV remodeling. To date, most therapeutic delivery strategies have involved intramyocardial biomaterial injections, although translation to acute MI patients is unlikely given the increased risk of ventricular rupture immediately post-MI. One promising, minimally invasive strategy is the systemic injection of nanoparticles. However, many of the investigated systems lack long-term retention within the MI. 

Researchers at the University of California, Davis have discovered a novel protocol to enable 3D printing with nanometer precision in all three dimensions using polyelectrolyte (PE) inks and atomic force microscopy.

Polydimethyl siloxane (PDMS) has many characteristics that make it the most popular candidate for producing organ-on-a-chip devices or mirco-physiological systems (MPS) devices. After crosslinking, PDMS has shown to be biologically compatible and amenable to many standard cell culture techniques due to it’s transparency, oxygen permeability, and low auto-fluorescence. However, due to PDMS’s hydrophobicity, molecules that are also hydrophobic partition into the PDMS to produce unpredictable concentrations in cell and media channels making it impossible to predict the actual dosing concentrations for drug investigations. This unpredictability is an obstacle for using organ-on-a-chip devices as screens for drug candidates in discovery stages.   Researchers at UC Berkeley have developed a simple coating procedure that allows the formation of substrate independent (universal) coatings. The researchers identified a novel compound able to form stable coatings that outperformed existing dip-coating precursor molecules in their ability to prevent absorbance of small molecules into a variety of organic and inorganic polymers, such as PDMS.
