Abstract:
In at least one illustrative embodiment, a field-effect transistor biosensor for detection of a pathogen includes a substrate and a channel formed from a two-dimensional monolayer or few-layer metal chalcogenide that is functionalized with a biorecognition element. The biorecognition element may be an antibody, such as an antibody for the SARS-COV-2 spike protein. A method for manufacturing the biosensor includes depositing an amorphous two-dimensional material on the substrate with pulsed laser ablation, crystallizing the amorphous two-dimensional material to generate a two-dimensional monolayer coupled to the substrate, and activating a surface of the two-dimensional material with the biorecognition element after crystallizing the amorphous two-dimensional material. The composition of the two-dimensional material may be tuned. The substrate may be photolithographically patterned. Other embodiments are described and claimed.

Abstract:
Compounds, such as cathinone derivatives, and pharmaceutical formulations that include the compounds. The compounds may have a first selectivity for a first receptor subtype that is at least 10 times greater than a second selectivity for a second receptor subtype from the same class of receptors. Methods of treating patients, which may include administering to a patient a pharmaceutical formulation that includes a compound, such as a cathinone derivative.
Abstract:
A method for producing at least one microneedle containing a vaccine for transdermal delivery of the vaccine to a patient includes preparing microparticles or nanoparticles of encapsulated vaccine by preparing a solution comprising a vaccine antigen and a biocompatible polymer matrix; and spray drying the solution to form the microparticles or nanoparticles. The method includes the further steps of preparing a film composition including at least one pre-polymer solution; preparing a suspension comprising the microparticles or nanoparticles and the film composition; loading the suspension into a 3D printer; printing, via the 3D printer, at least one microneedle made from the suspension; and, converting the pre-polymer solution into a cross-linked biopolymer by exposing the at least one microneedle to UV light. Also disclosed are microneedles containing a vaccine for transdermal delivery.
Abstract:
Stents are disclosed. The stents provide novel stent designs that can, in some cases, span bifurcations in a duct, such as the extrahepatic bile duct (EHBD) (e.g., where the right hepatic duct meets the left hepatic duct), without impeding bile flow from either duct branch. Methods of making and using stents are also disclosed.

Abstract:
A method for forming microspheres containing bioactive material, comprising dissolving a polymer matrix, such as albumin or beta-cyclodextrin, in an aqueous medium in a first vessel; contacting the dissolved polymer matrix with a crosslinking agent, such as glutaraldehyde, to crosslink the polymer matrix and the crosslinking agent; neutralizing with sodium bisulfate any excess crosslinking agent remaining after crosslinking is substantially complete; solubilizing in a second vessel a bioactive material in an aqueous solution; mixing the solubilized bioactive material together with the neutralized crosslinked polymer matrix in solution to form a mixture; and, spray drying the mixture to produce nanospheres, whereby substantial bioactivity of the biomaterial is retained upon cellular uptake.
Abstract:
A method of transdermal delivery of a vaccine, comprising preparing microparticles of encapsulated vaccine by spray drying a mixture of the vaccine and at least one polymer, and injecting the microparticles transdermally using a microneedle delivery apparatus.
