Herein we demonstrate a systematic investigation of chemically functionalizable, non-biofouling agarose films over large-area glass surfaces. Agarose films, prepared with various concentrations of aqueous agarose, were activated by using periodate oxidation to generate aldehyde groups at the termini of the agarose chains. The non-biofouling efficacy and binding capabilities of the activated films were evaluated by using protein and cellular patterning, performed by using a microarrayer, microcontact printing, and micromolding in capillaries. Characterization by using a fluorescence slide scanner and a scanning-probe microscope revealed that the pore sizes of the agarose films played an important role in achieving desirable film performance; the 0.2 wt % agarose film exhibited the optimum efficacy in this work.

Galactose oxidase has long captured the interest of the biocatalysis and biotechnology communities due to its unique catalytic characteristics and versatility with various substrates. In our previous studies, we demonstrated that galactose oxidase GAO-5F from Fusarium odoratissimum can oxidize agarose to produce a polyaldehyde polymer, which can be further crosslinked with gelatin to produce food packaging films. Despite its commendable catalytic performance, GAO-5F falls short of meeting the requirements for industrial applications.

Osteoarthritis (OA) is one of the biggest global health issues, affecting two thirds of the population and cannot be fully treated to return normal function or relieve joint discomfort. Oral fast-dissolving films offer a high medication loading capacity, targeted distribution, and increasing bioavailability. The current research explores the in vitro and in vivo efficacy of oral fast-dissolving film formulations containing bark extract.

Transdermal drug delivery provides therapeutic benefits over enteric or injection delivery because its transdermal routes provide more consistent concentrations of drug and avoid issues of drugs affecting kidneys and liver functions. Many technologies have been evaluated to enhance drug delivery through the relatively impervious epidermal layer of the skin. However, precise delivery of large hydrophilic molecules is still a great challenge even though microneedles or other energized (such as electrical, thermal, or ultrasonic) patches have been used, which are often difficult to be integrated into small wearable devices.

Gel-electromembrane extraction (G-EME) is an increasingly popular green variant of electromembrane extraction (EME). However, the electroendosmosis (EEO) flow associated with G-EME greatly limits the development of this technology. To address this challenge, the current study proposed the concept of confined G-EME (CG-EME), and a three-dimensional-printed modular device was elaborately designed to realize this concept.
