“…The estimate effectively presumes that the fracture is brittle and that the material deforms elastically all the way until the fracture. This appears to be a good approximation for both exine and cellulose films [38][39][40].…”

The mechanical structure of pollen grains, typically characterized by soft apertures in an otherwise stiff exine shell, guides their response to changes in the humidity of the environment. These changes can lead both to infolding but also to excessive swelling and even bursting of pollen grains. We use an elastic model to explore the mechanics of pollen grain swelling and the role that soft, circular apertures (pores) play in this process. We identify and explore a mechanical weakness of the pores, which are prone to a rapid inflation once the grain swells to a critical extent. This transition leads to the bursting of the grain and the release of its content. Our results shed light on the inactive part of the mechanical response of pollen grains to hydration once they land on a stigma as well as on bursting of airborne pollen grains during rapid changes in air humidity.

“…In order to purify BC, the pellicles are extracted from the fermented broth, followed by a mixture- Over time, the accumulation of these microfibrils will lead to the formation of the cellulose ribbon. A web-shaped interconnected pattern will be produced by this cellulose ribbon, with a sufficient amount of empty spaces existing between the fibers, which creates a highly microporous structure [21,22]. BC demonstrates a well-distributed 3D structure of nanofibers, with a large surface area, a high tensile strength, and with a water-absorbing capacity [11].…”

Cellulose is a naturally existing element in the plant’s cell wall and in several bacteria. The unique characteristics of bacterial cellulose (BC), such as non-toxicity, biodegradability, hydrophilicity, and biocompatibility, together with the modifiable form of nanocellulose, or the integration with nanoparticles, such as nanosilver (AgNP), all for antibacterial effects, contributes to the extensive usage of BC in wound healing applications. Due to this, BC has gained much demand and attention for therapeutical usage over time, especially in the pharmaceutical industry when compared to plant cellulose (PC). This paper reviews the progress of related research based on in vitro, in vivo, and clinical trials, including the overall information concerning BC and PC production and its mechanisms in wound healing. The physicochemical differences between BC and PC have been clearly summarized in a comparison table. Meanwhile, the latest Food and Drug Administration (FDA) approved BC products in the biomedical field are thoroughly discussed with their applications. The paper concludes on the need for further investigations of BC in the future, in an attempt to make BC an essential wound dressing that has the ability to be marketable in the global marketplace.
