Reduced bacterial attachment on surface modified hydrophobic fabric surface: a possible approach for safety enhanced packaging material

Chaudhari A.A., Rangan K.K., Sudarshan T.S., Singh S.R., Pillai S.R., Alabama State University, US

In the present study, three surface modified fabrics were investigated for their bacterial attachment properties using Salmonella enterica serovar Typhimurium (gram –ve) and Staphylococcus aureus (gram+ve) bacteria. Our results indicate that surface modified fabric show [...]

Characterization of silver-coated carbon nanotubes dispersed in a specifically formulated dispersant – NanoSperse AQ®

Chaudhari A.A., Singh S.R., Pillai S.R., Alabama State University, US

Silver-coated carbon nanotubes (AgCNTs) are well documented for their antibacterial properties. However, aqueous dispersions of AgCNTs could be less effective against bacteria due to their tendency to agglomerate when re-suspended in water. In this study [...]

A CMOS Lab-On-A-Chip For Neuron Monitoring And Stimulation

Ghallab Y.H., Ismail Y., Center of Nano Electronics and Devices (CND) at American University in Cairo/ Zewail City of Science and Technology, Cairo, Egypt, EG

Many tools have been established to monitor neural activity such as patch pipettes and microelectrodes, which are electrolyte filled glass tubes used to create intracellular contacts by rupturing the cell membrane and directly measuring the [...]

Electrochemical Detection of Alcohol using Enzyme Sensor with Chromatography Paper and its Potential Application as halal Sensor

Musa M.S., Kuretake T., Harada Y., Hori F., Uno S., Ritsumeikan University, JP

The Islamic law forbids Muslims from consuming food that contains porcine derivatives and alcohol, among others. The halal term is not limited to only the food ingredients but also considers the absence of non-halal species [...]

Novel silicon microdosimeter based on 3D cylindrical structures

Guardiola C., Carabe-Fernández A., Gomez F., Pellegrini G., Fleta C., Quirion D., Lozano M., University of Pennsylvania, US

A new design of a solid-state-detector based on silicon microfabrication is provided in this work in order to create a novel microdosimeter. This microdosimeter improves the performance of existing microdosimeters using three-dimensional microfabrication technology development. [...]

DETECHIP®: Developing a Molecular Sensing Device

Okuom M.O., Holmes A.E., Doane College, US

DETECHIP® is a detection system made of various sensors that has been shown to detect and discriminate between small molecules of interest, including various illicit drugs for and over-the-counter medications, explosives, pesticides and food spoilage [...]

Carcinogenicity Assessment Using Biosensors: Mitomycin-C As A Case Study

Alhadrami H.A., King Abdulaziz University, SA

This study enabled an empirical assessment of a model carcinogen borne in soil and its potency on human receptors. SOS-lux biosensors had numerous practical advantages over the traditional assays including procedural simplicity, ease of measurement [...]

Resistance and Potentiostatic Based Measurements of an Antibody Functionalized Conductive Polymer Coated Textile as a Biosensor

Bandremer A., Hebert A., Torosian S.D., Battacharyya D., Gleason K., McGraw S.K., Senecal A., Marek P., Food and Drug Administration, US

Effective food safety monitoring is challenged by the necessity to identify human infection capable microorganisms at sufficient infective doses and consumption levels. Regulatory agencies have developed methods for assessing food safety based on currently available [...]

Nanostructured Biomimetic Memristor Sensors Used for Therapeutic Monitoring of the Brain Cancer

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

Current technology is not available to provide a portable, simple and accurate real-time monitoring and treatment of cancers simultaneously in an early stage at a clinical setting. Challenges for developing such a tool, include the [...]

Multimodal Nano-Brain-Machine-Interface for Parallel Electrochemical NeuroSignal Sensing

Poustinchi M., Stacey G., Musallam S., McGill University, Neural Prosthetics Laboratory, CA

Thanks to technological advancements in recent decades, outstanding progress has been made in the field of neuroscience and neural engineering. Although the information processing in the brain is mostly done through neuron’s electrical activities, there [...]
