“Antimicrobial Hydrogels for Wound Healing”

Dr. Olga Makhlynets
Associate Professor, Department of Chemistry
Syracuse University
Tuesday, December 7th at 6:30 P.M.

 

Abstract

Fungal and bacterial agents such as methicillin-resistant Staphylococcus aureus (MRSA), E. coli, P. aeruginosa, and Candida species are associated with infections that have become a frequent issue that plagues hospitals. One strategy that has emerged to prevent and treat such infections is the use of antimicrobial gels in the form of wound fillers, implant coating, and for drug delivery. The use of silver compounds in wound healing is very prevalent due to their antimicrobial properties, however high concentrations of silver are toxic to mammalian cells.

The Makhlynets research group has developed a peptide that incorporates an unnatural amino acid, 3’-pyridyl alanine (3’-PyA), into its sequence that binds to silver and releases it slowly over time to overcome the issue of toxicity. In the presence of Ag(I) ions the peptide assumes a beta-sheet secondary structure and self-assembles into a strong hydrogel characterized by rheology, circular dichroism, and transmission electron spectroscopy. This hydrogel displays high potency against infectious agents while being non-toxic to connective tissue found in the body.

 

2021 Student Travel Awards

To encourage participations of students in local, regional, and national conferences organized by of the American Chemical Society and its affiliates and to create opportunities for students to enhance their scientific experiences and networking, the Orlando Local Section of the American Chemical Society offers travel awards to students who are in need of financial supplement for their conference participations. This year, the awards will be given to selected students who participate in the Florida Annual Meeting and Exposition (FAME), the Southeastern Regional Meeting of The American Chemical Society (SERMACS 2021), and the 262nd ACS National Meeting & Exposition. For each conference, up to two students will receive awards of up to $150, $250, and $500, respectively.

To apply, student applicant needs to prepare an application package (a single PDF file) that includes the following:

  • Brief introduction of applicant
  • Proof of acceptance to conference and acceptance of abstract
  • Brief explanation of why travel award from the Orlando Local Section of the American Chemical Society is necessary (especially those whose research projects are federal/industrially/privately funded)
  • Contact information of advisor (The award committee will request a statement from advisor indicating appropriate use of the travel award to registration, lodging, and/or travel expenses).

Application package should be sent via email to Awards Committee Chair (Dr. Darlene Slattery, dslattery1@cfl.rr.com) by 08/13/2021 for FAME applications, 10/15/2021 for SERMAC applications, and 08/01/2021 for ACS National Meeting. The committee will select awardees mainly based on applicant’s synergistic activities and financial needs (novelty of research project is a bonus criterion).

CATL Division Fall 2021 Student Travel Awards

The Catalysis Science and Technology (CATL) Division solicits applications for CATL-ChemCatBio Graduate Student Travel Awards that will cover the registration fee of graduate students presenting at the Fall 2021 ACS National Meeting scheduled to be held from 22-26 August 2021.
 
The travel awards aim to further the shared goals of the ACS CATL (https://www.acs-catalysis.org/) and ChemCatBio Consortium (https://www.chemcatbio.org/) to provide educational opportunities in catalysis, support professional development for young scientists, and foster diversity and inclusion in chemical process research.
 
To be eligible the student must be an ACS CATL Division Member. 

Please send as a single PDF file, in an email attachment: 
a) Notice of abstract acceptance for a CATL-sponsored symposium 
b) CV of the graduate student 
c) Nomination letter from the student’s PhD advisor 
d) ACS Member number of the nominator and the nominee
e) Whether or not the student has already registered for the ACS Meeting (if they have registered please also send a receipt and a postal address so we can send reimbursement)  
 
Include CATL REGISTRATION AWARD APPLICATION (in capital letters) as the subject. Forward documentation to the ACS CATL Assistant at contractor.acs.catl@gmail.com 
 
The deadline for application is 2 August 2021.
