Abstract

Rapid, sensitive, and specific point-of-care testing for pathogens is crucial for disease control. Lateral flow assays (LFAs) have been employed for nucleic acid detection, but they have limited sensitivity and specificity. A fusion of catalytically inactive Cas9 endonuclease and a relaxase for example, VirD2 are used for sensitive, specific nucleic acid detection by LFA. VirD2-dCas9 specifically binds the target nucleic acid sequence via dCas9 and covalently binds to a FAM-tagged oligonucleotide via VirD2. The biotin label and FAM tag are detected using a LFA. This system, termed Vigilant (VirD2-dCas9 guided and LFA-coupled nucleic acid test) is coupled to reverse transcription-recombinase polymerase amplification to detect pathogenic nucleic acid of interest in a sample, it exhibits an impressive limit of detection and shows no cross-reactivity, thus reducing incidents of false positives. Vigilant offers an easy-to-use, rapid, cost-effective, and robust detection platform for SARS-CoV2.

Abstract

Described are nanogels suitable for scaffolds for encapsulating human dermal fibroblasts for non-healing chronic wounds. Peptide nanogels Ac-IVZK-NH2 and Ac-IVFK-NH2 are selected and produce silver nanoparticles in situ within the nanogels to assess their efficacy on micropigs with full-thickness excision wounds. The in situ generation of the silver nanoparticles is done solely through UV irradiation and no reducing agent is used. Application of the peptide nanogels on full thickness micropig wounds demonstrate that the scaffolds are biocompatible and do not trigger wound inflammation. This suggests that scaffolds are safe for topical application. A comparison of the effect of both nanogels even without the addition of the silver nanoparticles, reveals that the scaffold itself has a high potential as an antibacterial agent, which may suppress both the inflammatory reaction and the activity of proteases. The effect on wound closure of the peptide nanogels is comparable to standard care hydrogels.

Abstract

Nature-inspired smart materials offer numerous advantages over environment- friendliness and efficiency. Emulating the excellent adhesive properties of mussels foot proteins, where the Lysine is in close proximity with the 3, 4-dihydroxy-L-phenylalanine (DOPA), disclosed embodiments report the synthesis of a novel photo-curable peptide-based adhesive consisting exclusively of these two amino acids. The disclosed adhesive is a highly concentrated aqueous solution of a monomer, a crosslinker and a photoinitiator. No toxicity of the disclosed adhesive was observed when the cytocompatibility on human dermal fibroblast cells was assessed. Lap-shear adhesion measurements on plastic and glass surfaces and comparison with different types of commercial adhesives showed that the adhesive strength of the disclosed glue is comparable when applied in the air and superior when used underwater. Given the convenience of the facile synthesis, biocompatibility, ease of application underwater and high adhesive strength, disclosed embodiments expect that the disclosed adhesive may find application, but not limited, to the biomedical field.

Abstract

A facile strategy is used to synthesize the gold nanoparticles via a green and simple approach showing self-alignment on the assembled nanofibers of ultrashort oligopeptides as a composite material. A photochemical reduction method is used, without requiring any external chemical reagents for the reduction of gold ions and producing gold nanoparticles of size ca. 5 nm under mild UV light exposure. The specific arrangement of gold nanoparticles on peptide nanofibers may indicate electrostatic interactions of two components and interactions with the amino group of the peptide building block. The gold-peptide nanoparticle composites show the ability as a catalyst to degradation of environmental pollutant p-nitrophenol to p-aminophenol, and the reaction rate constant for catalysis is 0.057 min−1 at a 50-fold dilute sample of 2 mg/mL and 0.72 mM gold concentration in the composites. This colloidal strategy helps researchers to fabricate the metalized bioorganic composites for biomedical and bio-catalysis applications.

Abstract

Newly developed peptide nanogels provide native cues to human dermal fibroblasts as well as mouse myoblast cells and promote proliferation and extensive network formation in vitro is presented. The results represent an improvement in the fabrication of dermal grafts as well as 3D skin models. In addition, the application of these ultrashort peptide nanogels on full-thickness wounds in a minipig model demonstrated biocompatibility with the minipig skin tissue, as the peptide nanogels did not trigger wound inflammation. Thus, they can be considered as a safe biomaterial for topical applications. It is shown that both peptides are printable. The ability to print peptides and the return of high cell viability within the printed construct will open up the possibility of 3D bioprinting of different cell types in future.

Abstract

A modified approach for coral restoration by merging 3D printing and molding techniques is presented. This is achieved by 3D scanning live coral specimens, retrieved from sea dives, to obtain a CAD model of the complete coral 3D construction with complex geometries. Select areas of the model are flattened to create a 2D base for micro-fragment adhesion. From the CAD models, disclosed embodiments propose two methods of fabrication. Method A consists of 3D printing the CAD models with commercial thermoplastic materials to create a negative mold, subsequently loaded with synthesized Calcium Carbonate Photoinitiated (CCP) ink to form an eco-friendly coral skeleton. Method B uses syringe-based extrusion 3D printing to directly print a coral skeleton with CCP ink. Both methods are evaluated as a combined proof-of-concept process, 3D CoraPrint, for coral gardening and restoration and providing details required for mimicking coral and bone 3D structures for implantation in bone grafting applications.

Abstract

A terminal is configured to communicate with another terminal using an optical link. The terminal includes an optical transmitter configured to emit an optical beam, an optical receiver configured to receive an optical signal, and a computing device configured to control the optical transmitter and to receive the optical signal from the optical receiver. The computing device is configured to establish the optical link with the another terminal by, (1) dividing an area of uncertainty, where the another terminal is located, into one spherical region (1) and an annulus ring (2)−(1), wherein each of (1) and (2) are spherical regions with radii 2>1, (2) scanning first the spherical region (1) with the optical beam, and (3) scanning second the spherical region (1) and the annulus ring (2)−(1) with the optical beam.

Abstract

A method is disclosed for modeling fluid flow through a fracture. The method includes obtaining a normal stress, and a shear stress and determining a first three-dimensional (3D) aperture model. Further, the method includes estimating a normal fracture closure displacement under the normal stress and a fracture dilation under the shear stress and simulating a fluid flow through a second 3D aperture model of the fracture. The second 3D aperture model of the fracture is based on the first 3D aperture, the normal fracture closure displacement, and the fracture dilation. Additionally, the method includes calculating a permeability of the second 3D aperture model of the fracture based on the simulated fluid flow.

Abstract

A microneedle balloon catheter includes a balloon fluidically coupled to a first fluidic channel and microneedles fluidically coupled to a second fluidic channel. The microneedles are on an exterior surface of the balloon. The catheter also includes a guiding sheath. In a first position of the microneedle balloon catheter the balloon, the microneedles, and a portion of the first and second fluidic channels are housed within the guiding sheath. In a second position of the microneedle balloon catheter the balloon and the microneedles are arranged outside of the guiding sheath. The first and second fluidic channels are fluidically isolated from each other.
