Fast Prototyping and Ex Vivo Evaluation of Dissolvable Millineedle Patches Made by Solvent Casting from CO2 Laser Ablated Elastomer Molds

Advanced Materials Interfaces, EarlyView.
CO2 laser ablation, a fast, inexpensive, and reproducible method, is used to create flexible elastomer molds with millimeter‐long cavities for the fabrication of dissolvable polymer needles. Made from PVP, these milli‐needles achieve ≈560 µm penetration into porcine skin, demonstrating their potential for effective transdermal drug delivery.

Evaporation‐Enhanced Redox Cycling for Rapid Detection of Attomolar SARS‐CoV‐2 Virions Using Nanolithography‐Free Electrochemical Devices

Advanced Materials Technologies, EarlyView.
This study presents microfabricated electrochemical sensors for detecting ultralow viral particles counts through evaporation‐enhanced redox cycling (E2RC). To achieve sub‐micrometer gap in interdigitated microelectrodes, a scalable, nanolithography‐free fabrication method is developed.

Risk factors associated with the intensity of COVID-19 outbreaks in Canadian community settings: a retrospective analysis of outbreak-level surveillance data

BMC Public Health
Background The severity of COVID-19 outbreaks is disproportionate across settings (e.g., long-term care facilities (LTCF), schools) across Canada. Few studies have examined factors associated with outbreak severity to inform prevention and response.

Simulating the Spread of Influenza Pandemic of 2009 Considering International Traffic [PDF]

arXiv, 2010
Pandemics have the potential to cause immense disruption and damage to communities and societies. In this paper, we model the Influenza Pandemic of 2009. We propose a hybrid model to determine how the pandemic spreads through the world. The model considers both the SEIR-based model for local areas and the network model for global connection between ...

Chitosan, Gelatine, and Cellulose Based Hydrogels for the Removal of Potentially Toxic Elements from Aquaculture Water: A Comparative Study

Advanced Sustainable Systems, EarlyView.
Hydrogels made of chemically modified biopolymers are easy to prepare and cost‐effective, they have proven to be effective materials for the simultaneous removal of seven potentially toxic elements (PTEs) from ultrapure and real water samples. The cellulose‐based one seems the best for single treatments while the gelatine‐based one seems the most ...

A Hybrid Model for Disease Spread and an Application to the SARS Pandemic [PDF]

arXiv, 2010
Pandemics can cause immense disruption and damage to communities and societies. Thus far, modeling of pandemics has focused on either large-scale difference equation models like the SIR and the SEIR models, or detailed micro-level simulations, which are harder to apply at a global scale.
