New Publication by Erika Fleming

Congratulations to Erika Fleming on publishing a research article in Food Biophysics. The article, entitled “Mucoadhesive biopolymer nanoparticles for encapsulation of lipophilic nutrients with enhanced bioactivity”, reports the various methodologies to evaluate the mucoahesive properties of biopolymer nanoparticles, including traditional physical and chemical methods, as well as the state-of-the-art analytical technique, i.e., Quartz Crystal Microbalance with Dissipation Monitoring (QCM-D). QCM-D is an ultra-sensitive instrument for real-time characterization of interfaces and molecular interactions. This is a collaborative research project between our lab and Dr. Boce Zhang‘s lab at the University of Massachusetts Lowell. Please read the article here.

Novelty Statement

Given the exceptional mucoadhesive properties, the biopolymer nanoparticles that we prepared make an excellent candidate for the encapsulation of lipophilic nutrients with low bioavailability.

Congratulations to Taoran Wang and Wusigale (co-first authors) on having their research paper published in Advanced Composites and Hybrid Materials. The article, entitled "Polydopamine-coated chitosan hydrogel beads for synthesis and immobilization of silver nanoparticles to simultaneously enhance antimicrobial activity and adsorption kinetics", showcases our recent collaborative project on developing the innovative and multi-functional chitosan-based hydrogel beads with immobilized with silver nanoparticles (AgNPs) via polydopamine coating to simultaneously enhance antimicrobial and adsorption activity. The findings from this study demonstrate that AgNPs (2.5 nm) not only significantly improved the adsorption performance of the chitosan hydrogel beads and but also dramatically enhanced their antibacterial activity against both Gram-negative bacteria than Gram-positive bacteria. This work has developed an integrative approach to efficiently control both the microbial and chemical quality of wastewater. Please read the paper here.

Congratulations to Jingyi Xue on having her research paper published in Food Hydrocolloids. The article, entitled "Development of novel biopolymer-based dendritic nanocomplexes for encapsulation of phenolic bioactive compounds: A proof-of-concept study", reports our research findings that demonstrate an innovative strategy to develop dendritic nanoparticles from food biopolymers without using organic solvents or synthetic chemical. The food biopolymers used in this study include phytoglycogen and zein, carbohydrate and protein respectively, both from corn. Antimicrobial phytochemicals are encapsulated into such nanoparticles which exhibited significantly improved bioactivity, including higher antioxidant activity and stronger antibacterial efficacy against foodborne human pathogens. The potential of these nanocomplexes as carriers for lipophilic and phenolic antimicrobial compounds opens up new avenues for nanotechnology enabled approaches to ensure food safety and quality.

New Publication by Wusigale

Congratulations to Wusigale on publishing a new research paper in International Journal of Biological Macromolecules, from the research during her visit at UConn. The article entitled "Partition and stability of folic acid and caffeic acid in hollow zein particles coated with chitosan" reports a study on the preparation of chitosan-coated hollow zein particles using calcium phosphate as a sacrificing template for co-encapsulation of folic acid and caffeic acid. Partition, photostability, and antioxidant capacity of bioactive compounds were comprehensively studied. Findings in this study shed some light on the design of carriers for co-delivery of hydrophilic compounds in acidic condition. Read the article here.

Congratulations on Erika Fleming on having her new Personal Account article in ES Food and Agroforestry. The articles entitled "Dietary Patterns During National Lockdowns are at Odds with Recommendations for Preventing Morbidity and Mortality of COVID-19" provided a unique perspective to highlight the role that diet plays in both general immune function and specifically with SARS-CoV-2 may lead to better health outcomes globally. In addition, the role that national lockdowns have had in lifestyle changes are discussed, and how these shifts may exacerbate the morbidity and mortality of COVID-19.
