Researchers Attend Annual Meeting of the Adhesion Society

Adhesion Society Meeting Graphic

Rupak Rajachar (BioMed), Bruce Lee (BioMed), Ariana Tyo (BioMed) and Saleh Akram Bhuiyan (BioMed) attended the 43rd Annual Meeting of the Adhesion Society in Charleston, South Carolina.

Rajachar chaired a session entitled “Biomedical Adhesion.” Lee gave an oral presentation entitled “Tuning the ROS Release from Catechol-containing Bioadhesive.”

Tyo gave an oral presentation entitled “Adhesive Antimicrobial Polydopamine Surface Coatings to Prevent Biofilm Formation on Stainless Steel.” The content of this talk was recently published in Frontiers in Chemistry.

Bhuiyan was a finalist for the Peebles Award for Graduate Student Research in Adhesion Science and gave an oral presentation entitled “In Situ Deactivation of Catechol-Containing Adhesive using Electrochemistry.” The content of this talk was recently published in the Journal of the American Chemical Society and was highlighted in the Michigan Tech News.

The meeting was February 23-26, 2020.


Bruce Lee Publishes a Study of a Multifunctional Microgel

ACS Applied Materials and Interfaces cover.

Bruce Lee (BioMed) published a paper titled “Iron Magnetic Nanoparticle-Induced ROS Generation from Catechol-Containing Microgel for Environmental and Biomedical Applications” in ACS Applied Materials & Interfaces.

The coauthors are graduate student Zhongtian Zhang (BioMed), undergraduate student Max Reaume (BioMed), postdoctoral researcher Bo Liu (BioMed) and collaborators Chao Zhou and Min Wu from Changzhou University and Guangdong University of Technology, respectively.

Extract

Reactive oxygen species (ROS) can degrade organic compounds and function as a broad-spectrum disinfectant. Here, dopamine methacrylamide (DMA) was used to prepare catechol-containing microgels, which can release ROS via metal-catechol interaction. A combination of the microgel and iron magnetic nanoparticle (FeMNP) significantly reduced the concentration of four organic dyes (Alizarin Red S, Rhodamine B, Crystal Violet, and Malachite Green) and an antibiotic drug, ciprofloxacin, dissolved in solution.

Additionally, catechol chelates heavy metal ions, resulting in their removal from solution and repurposed these metal ions for dye degradation.

This multifunctional microgel can potentially be used for environmental applications for the removal of organic pollutants and heavy metal ions from wastewater, as well as reducing bacterial infection in biomedical applications.


Bruce Lee Publishes in Chemical Society Reviews

Bruce Lee (BioMed) published a review article in Chemical Society Reviews entitled “Catechol-functionalized hydrogels: biomimetic design, adhesion mechanism, and biomedical applications.”

Chemical Society Reviews is the Royal Society of Chemistry’s leading reviews journal and publishes high-impact articles at the forefront of the chemical sciences. (Impact Factor: 40.443)

https://doi.org/10.1039/C9CS00285E

This review compiles state-of-the-art examples and details progress in the design and development of adhesive hydrogel materials based on mussel-inspired catechol chemistry. From a fundamental perspective, two main aspects have been examined: the role of water in undermining adhesion in hydrogels and the adhesive mechanism involving catechol-containing adhesives and coatings.

A Critical Review of Microelectrode Arrays and Strategies for Improving Neural Interfaces

Interaction of neuronal cells with MEA shank.
Interaction of neuronal cells with MEA shank.

Given mankind’s limited ability to treat damage to the human nervous system, neural interface systems (NISs) have emerged as an attractive alternative to conventional therapies. For a NIS to work, a microelectrode array (MEA) must be surgically implanted into the brain to allow an external computer to read and interpret neuronal signals for various applications. Dr. Zhao’s Lab has recently published a review paper titled “A Critical Review of Microelectrode Arrays and Strategies for Improving Neural Interfaces” in Advanced Healthcare Materials.
https://doi.org/10.1002/adhm.201900558

This review article, authored by Morgan Ferguson (MS student), Dhavan Sharma (PhD candidate), David Ross (former MS student), and Dr. Feng Zhao, provides critical insight into the recent advances in strategies for improving NIS microelectrode array biocompatibility and neural interfacing capabilities, including alterations in microelectrode array surface properties (both surface chemistry and topography), surface geometry, and stiffness. Individually, each strategy provides varying degrees of success in altering microelectrode array biocompatibility, electrical conductivity, signal maintenance, and/or overall longevity along with the severity of foreign body response. By using a multiprong design for MEAs (one combining modifications to the surface, geometry, and hardness into one MEA) instead of using a lone modification, it could allow NISs to operate for a much longer period.
