    Structured Review

    Envisiontec GmbH hyaluronic acid liquid-core hydrogel (halc) swnt sensor solution
    Representative photographs of the four types of <t>hydrogel-SWNT</t> sensor platforms with accompanying fluorescence image at 990 nm. Images depicting fluorescence intensity of the SWNT sensors are shown with red representing the highest intensity and blue representing the lowest intensity normalized to each image. Fluorescence images confirm association of SWNT sensors into hydrogel platforms. a) Alginate composite: AC, hydrogels show intensity spread across the entirety of the gel; b) hyaluronic acid liquid-core: <t>HALC</t> hydrogels show an even distribution of intensity within the core and little to no fluorescence outside of the core (edges); c) alginate liquid-core: ALC hydrogels did show fluorescence only within the core, but fluorescence is not well distributed; and d) surface-tethered alginate: STA hydrogels show and even distribution of fluorescence across the gel.

    Techniques Used: Fluorescence

    SWNT sensor response to analyte exposure is dependent on the hydrogel delivery platform. Quenching curves shown are the average of three trials (n = 3). a) ALC hydrogels showed delayed sensor response similar to what is observed for the AC gel. The STA and HALC hydrogels provide a stabilization platform to localize the SWNT while allowing free sensor interaction with the analyte, leading to sensor response similar to that observed in FF SWNT. b) 2HALC hydrogels had a significantly delayed sensor response compared to HALC indicating a response rate dependence on volume to surface area ratio of liquid core hydrogels.
