Ionic transport through nanofluidic systems is a problem of fundamental interest in physics and has broad relevance desalination, fuel cells, batteries, filtration, drug delivery. When the dimension fluidic system approaches size molecules solution, fluid properties are not homogeneous departure behavior observed with respect to continuum-based theories. Here we present systematic study charged neutral small an ideal platform precise channels from sub-microscale ultra-nanoscale (<5 nm)....
Induced hyperthermia has been demonstrated as an effective oncological treatment due to the reduced heat tolerance of most malignant tissues; however, techniques for generation within a target volume are insufficiently selective, inducing heating and unintended damage surrounding healthy tissues. Plasmonic photothermal therapy (PPTT) utilizes light in near-infrared (NIR) region induce highly localized gold nanoparticles, acting exogenous chromophores, while minimizing nearby However,...
SignificanceAccurate values of skin optical properties are essential for developing reliable computational models and optimizing imaging systems. However, published show a large variability due to variety factors, including differences in sample collection, preparation, experimental methodology, analysis.AimWe aim explore the influence storage conditions on excised from 400 1100 nm.ApproachWe utilize double integrating sphere system inverse adding-doubling approach determine absorption, μa,...
General adoption of advanced treatment protocols such as chronotherapy will hinge on progress in drug delivery technologies that provide precise temporal control therapeutic release.
Abstract Background and Objectives Photothermal therapies have limited efficacy application due to the poor penetration depth of light inside tissue. In earlier work, we described development novel fiberoptic microneedles provide a means mechanically penetrate dermal tissue deliver directly into localized target area. This paper presents an alternate microneedle design with capability delivering more diffuse, but therapeutically useful photothermal energy. Laser lipolysis is envisioned as...
Large laser facilities have recently enabled material characterization at the pressures of Earth and Super-Earth cores. However, temperature compressed materials has been largely unknown, or solely relied on models simulations, due to lack diagnostics under these challenging conditions. Here, we report temperature, density, pressure, local structure copper determined from extended x-ray absorption fine velocimetry up 1 Terapascal. These results nearly double highest pressure which reported...
Shallow light penetration in tissue has been a technical barrier to the development of light-based methods for vivo diagnosis and treatment epithelial carcinomas. This problem can potentially be solved by utilizing minimally invasive probes deliver directly target areas. To develop this solution, fiber optic microneedles capable delivering either imaging or therapy were manufactured tapering step-index silica-based optical fibers employing melt-drawing process. Some have sharper tips...
Novel approaches to achieve local, intratumoral drug delivery have the dual benefit of reducing systemic toxicity while enhancing efficacy for malignant cells. We developed a new implantable system combining next-generation BioNEMS nanofluidic membrane with parallel nanochannels that offers controlled release biomolecules. Based on concentration-driven diffusive transport, nanochannel membranes provide “drug agnostic” mechanism. Integrating this nanotechnology within small capsule permits...

Abstract There is no all-encompassing or universally accepted definition of the difficult airway, and it has traditionally been approached as a problem chiefly rooted in anesthesiology. However, with airway obstruction reported second leading cause mortality on battlefield first-pass success (FPS) rates for out-of-hospital endotracheal intubation (ETI) low 46.4%, need to better understand context prehospital setting clear. In this review, we seek redefine concept “difficult airway” so that...
Microneedles have been an expanding medical technology in recent years due to their ability penetrate tissue and deliver therapy with minimal invasiveness patient discomfort. Variations design allowed for enhanced fluid delivery, biopsy collection, the measurement of electric potentials. Our novel microneedle attempts combine many these functions into a single length silica tubing capable both light delivery terminating sharp tip less than 100 μm diameter. This paper focuses on flow aspects...
Implantable devices may provide a superior means for hormone delivery through maintaining serum levels within target therapeutic windows. Zero-order administration has been shown to reach an equilibrium with metabolic clearance, resulting in constant concentration and bioavailability of released hormones. By exploiting surface-to-molecule interaction nanochannel membranes, it is possible achieve long-term, diffusive release agents from implantable reservoirs. In this study, we sought...
