A compact syringe-assisted vacuum-driven micropumping with a constant flow rate

Wang A., Koh D., Schneider P., Oh K.W., University at Buffalo, US

Abstract In this paper, a simple syringe-assisted pumping method was introduced. Compared with previous study [1], the proposed design does not require pre-designed vacuum chambers, the multiple pumps can be integrated into one device and [...]

Physical and Chemical Transformations of Silver Nanomaterial-containing Textiles After Use

Gorka D.E., Gorham J.M., National Institute of Standards and Technology, US

Nanomaterials have been increasingly used in consumer products and silver nanomaterials (AgNMs) especially have been used for their antibacterial properties. Increased use of AgNMs in consumer goods will result in increased disposal and entrance into [...]

Exposure Assessment Framework for Materials Selection in Consumer Products

Liong M., Exponent, Inc., US

The use of exposure and risk assessment methodologies is crucial in materials selection for consumer products, particularly those involving long-term dermal contact. While biocompatibility test procedures designed for medical devices, such as those described in [...]

Numerical investigation of Electric field, Ion Transport and pH damage during Electrochemical Treatment of Tumors: Effects of physicochemical reactions and chlorine bleaching

Mokthare A., Reddy S.K., Furlani E.P., University at Buffalo, US

Electrochemical therapy (EChT) is a promising alternative to conventional tumor treatment due to its relatively high efficiency, flexibility, reduced side effects and versatility. Tumor electrolysis, a form of EChT, utilizes low-level direct electric current (DEC). [...]

Overcoming Challenges in Manufacturing Scale-Up of Plasmonic Gold Nanorods: Bringing Photothermal Therapy to the Clinic.

Pagliaro L., Siva Therapeutics Inc, US

Siva Therapeutics is developing a simple, safe, and effective adjunct cancer treatment termed Targeted Hyperthermia™, which generates therapeutic heat emanating from within solid tumors using systemically injected precision gold nanorods and an infrared light engine [...]

The modular synthetic approach that was developed to design a spectral library of core-shell nanoparticle contrast agents, which will have broad applications in biomedical imaging due to the potential for multi-modal imaging (e.g., fluorescence, MRI, [...]

RECAL: A New Ultrastable Luminescent Probe for Bioimaging

Borders B.C., Kang C.H., Brozik J.A., Photon Biosciences, LLC, US

Luminescent probes, such as fluorescent proteins, fluorescent dyes, phosphorescent dyes, and quantum dots, are important tools in biology, biophysics, and medical diagnostics. While these tools are incredibly useful and are suitable for use in many [...]

Functionalized Carbon Nanotube-based Microelectronic Sensor Array for Early Diagnosis of Alzheimer’s Disease

Johnston A.S., Tang Y., Alam M.M., InnoSense LLC, US

We designed and developed a lab-on-a-chip for the early diagnosis of Alzheimer’s Disease (AD) based on our patent-pending innovative nanotechnology by utilizing patterned microelectronic sensor devices for detecting Food and Drug Administration (FDA)-approved AD biomarkers [...]

Nanobiomimetic Superlattice Superconductive/Memristive Organometallic Devices at Room Temperature Serve as Chronoamperometric Sensors for sub fg/mL Collagen-1 Detection in Human Serum

Chen E.T., Thornton J.T., Kissinger P.T., Duh S-H, Advanced Biomimetic Sensors, Inc., US

Superconductive/Memristive devices have potential applications in supercomputing and in health industry was proposed in literature. Clinically detection range at low concentration for collagen-1 is difficult to accomplish due to the denaturing of protein Matrix Matelloprotinase-2 [...]

Hybrid Programmable Peptide Crosslinkers as Enzyme-Regulated Drug Delivery Vehicles

Rouge J.L., University of Connecticut, US

Biology has evolved the quintessential nucleic acid delivery vehicle, the virus, using proteins built from self-assembled peptide subunits. These viral protein coats are then degraded by specific enzymes, depending on their location, releasing their contents [...]
