The broader impact/commerical potential of this I-Corps project involves the use of brochosome-inspired coatings for optical, energy, and sustainability applications. Brochosomes are intricately structured microscopic granules secreted by insects and typically found on their body surface. The proposed brochosome-inspired coating technology could be integrated into camera or sensing devices to suppress stray reflections and to further enhance the sensor sensitivity. In addition, the brochosome-inspired coating could be engineered and incorporated onto solar panels to enhance optical transmission to improve solar energy harvesting. The antireflective coating could also be applied onto glass and window surfaces to improve energy efficiency of buildings, in addition to serving as a bird-friendly coating to reduce bird collisions for environmental sustainability. This I-Corps project is based on a brochosome-inspired optical coating characterized by three-dimensional, hierarchical micro- and nanostructures to suppress reflection from ultraviolet to near-infrared light at different incident angles. The proposed technology has demonstrated that brochosome-inspired coatings can be applied onto various surfaces and can prevent reflection of ultraviolet to near infrared light by as much as ~99%. The antireflective performances of the brochosomes-inspired coating can be tailored by engineering the geometries of the micro- and nanostructures suitable for various optical applications.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

这个I-Corps项目的更广泛的影响/潜在价值涉及将brochosome启发的涂层用于光学，能源和可持续性应用。Brochosomes是昆虫分泌的结构复杂的微观颗粒，通常存在于它们的体表。 所提出的brochosome灵感涂层技术可以集成到相机或传感设备，以抑制杂散反射，并进一步提高传感器的灵敏度。此外，这种以brochosome为灵感的涂层可以被设计并结合到太阳能电池板上，以增强光传输，从而改善太阳能的收集。抗反射涂层还可以应用于玻璃和窗户表面，以提高建筑物的能源效率，此外还可以作为鸟类友好涂层，减少鸟类碰撞，以实现环境可持续性。这个I-Corps项目是基于一种以brochosome为灵感的光学涂层，其特征是三维，分层的微米和纳米结构，以抑制不同入射角度的紫外光到近红外光的反射。所提出的技术已经证明，brochosome启发的涂层可以应用到各种表面上，并且可以防止紫外线到近红外光的反射高达~ 99%。该奖项反映了NSF的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。
