GraPhage13 aerogels (GPAs) are ultralow density, porous structures fabricated through the self-assembly of graphene oxide (GO) and M13 bacteriophage. Given GPA's high surface area extensive network, properties typically associated with highly adsorbent materials, it is essential to characterize its sorption capabilities, a focus on unlocking potential for advanced applications in areas such as biomedical sensing environmental monitoring. Herein, water, ethanol acetone GPA were explored using dynamic vapor (DVS). was found be hygroscopic, capacity 0.68 ± 0.02 g/g, double that conventional desiccant silica gels 20% higher than GO laminates. This remarkable capacity, along kinetics, influenced by both morphology strong interactions between water molecules functional groups within GPA. The low hysteresis stability during repeated sorption–desorption cycles highlight reversibility sorption. While shows lower acetone, tuneability presents opportunities improving sorption, exceeds similar carbon-based materials. These findings underscore capability versatility adsorption, paving way toward integration into graphene-based devices applications.
