Laser‐Microscribed Glass Enables Surface‐Microfluidics‐Facilitated, Affordable, Rapid Cancer Diagnosis

Advanced Functional Materials, EarlyView.
A transparent, laser‐microscribed glass platform enables cancer diagnosis within 1 h—much faster than histology, which takes days, and free from the chemical or contrast risks of MRI or CT scans. The antibody‐functionalized rough glass surface captures viable cancer cells directly from suspension, allowing instant optical readout and offering a rapid ...

High Entropy Wide‐Bandgap Borates with Broadband Luminescence and Large Nonlinear Optical properties

Advanced Functional Materials, EarlyView.
High‐entropy rare‐earth borates exhibit excellent nonlinear optical and broadband luminescence properties arising from multi‐component doping, chemical disorder, increased configurational entropy, and increased lattice and electronic anharmonicity. This formulation enabled us to obtain a large, environmentally stable single crystal with 3X higher laser‐

Designing Asymmetric Memristive Behavior in Proton Mixed Conductors for Neuromorphic Applications

Advanced Functional Materials, EarlyView.
Protonic devices that couple ionic and electronic transport are demonstrated as bioinspired neuromorphic elements. The devices exhibit rubber‐like asymmetric memristive behavior with slow voltage‐driven conductance increase and rapid relaxation, enabling simplified read–write operation.

Mapping Nanoscale Buckling in Atomically Thin Cr2Ge2Te6

Advanced Functional Materials, EarlyView.
Atomic‐resolution STEM is used to resolve nanoscale buckling in monolayer Cr2Ge2Te₆. A noise‐robust image analysis reconstructs three‐dimensional lattice distortions from single plan‐view images, revealing pronounced defect‐driven nm‐scale out‐of‐plane buckling.

Sustained-release amorphous solid dispersions

Drug Delivery and Translational Research, 2018
The use of amorphous solid dispersions (ASD) to overcome poor drug solubility has gained interest in the pharmaceutical industry over the past decade. ASDs are challenging to formulate because they are thermodynamically unstable, and the dispersed drugs tend to recrystallize.

Dissolution testing of amorphous solid dispersions

International Journal of Pharmaceutics, 2013
The main purpose of this study was to investigate the effect of different polymers, with varying physicochemical properties and molecular weight on the stability and dissolution of co-milled amorphous solid dispersions (ASDs) of piroxicam (PRX). The stability of amorphous PRX (aPRX) in ASDs was significantly improved by the polymers.

Molecular-Level Examination of Amorphous Solid Dispersion Dissolution

Molecular Pharmaceutics, 2021
Amorphous solid dispersions (ASDs) are commonly used to orally deliver small-molecule drugs that are poorly water-soluble. ASDs consist of drug molecules in the amorphous form which are dispersed in a hydrophilic polymer matrix. Producing a high-performance ASD is critical for effective drug delivery and depends on many factors such as solubility of ...

Characterization of amorphous solid dispersions

Journal of Pharmaceutical Investigation, 2017
The study of amorphous solid dispersions (ASDs) is currently one of the most exciting areas in pharmaceutics. Research has shown that ASDs offer unique advantages in improving the bioavailability of poorly water-soluble drugs over conventional delivery systems.

Assessing the performance of amorphous solid dispersions

Journal of Pharmaceutical Sciences, 2012
The characterization and performance of stable amorphous solid dispersion systems were evaluated in 40 research papers reporting active pharmaceutical ingredient (API) dissolution and bioavailability from various systems containing polymers. The results from these studies were broadly placed into three categories: amorphous dispersions that improved ...

Forced Solid-State Oxidation Studies of Nifedipine-PVP Amorphous Solid Dispersion

Molecular Pharmaceutics, 2022
In the present study, the oxidative degradation behavior of nifedipine (NIF) in amorphous solid dispersions (ASDs) prepared with poly(vinyl pyrrolidone) (PVP) with a short (K30) and a long (K90) chain length was investigated. The ASDs were prepared via dry ball-milling and analyzed using Fourier transform infrared (IR) spectroscopy, X-ray scattering ...
