In addition to glycemic control, various clinical treatments such as wound dressings, hyperbaric oxygen therapy, and phototherapy have been employed to manage these wounds. Low-level light therapy has emerged as an effective, noninvasive, and painless therapeutic approach for wound management. However, the bulkiness of traditional light sources and the need for frequent clinic visits have limited its widespread adoption. We have developed a wearable, flexible light-emitting bandage with cyanobacterial impregnation (LEB@Cyan). The bioactive bandage is designed to provide sustained oxygen generation and robust photobiomodulation, promoting keratinocyte migration, fibroblast proliferation, and angiogenesis. This addresses the hypoxic conditions and enhances bioenergetic supply to accelerate the healing process of diabetic wounds. In detail, the wound area of diabetic rats treated with LEB@Cyan showed significant reductions of 74.76% and 96.32% compared with that of LEB-treated diabetic rats and untreated diabetic rats, respectively. Such self-oxygenated wearable light-emitting fabric holds great promise for future clinical and commercial applications, potentially revolutionizing the management of chronic diabetic wounds.","PeriodicalId":223078,"journal":{"name":"Advanced Photonics Nexus","volume":"4 04","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-06-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147918604","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Lam","doi":"10.1117/1.apn.3.5.056002","DOIUrl":"https://doi.org/10.1117/1.apn.3.5.056002","url":null,"abstract":". Leveraging an optical system for image encryption is a promising approach to information security since one can enjoy parallel, high-speed transmission, and low-power consumption encryption features. However, most existing optical encryption systems involve a critical issue that the dimension of the ciphertexts is the same as the plaintexts, which may result in a cracking process with identical plaintext-ciphertext forms. Inspired by recent advances in computational neuromorphic imaging (CNI) and speckle correlography, a neuromorphic encryption technique is proposed and demonstrated through proof-of-principle experiments. The original images can be optically encrypted into event-stream ciphertext with a high-level information conversion form. To the best of our knowledge, the proposed method is the first implementation for event-driven optical image encryption. Due to the high level of encryption data with the CNI paradigm and the simple optical setup with a complex inverse scattering process, our solution has great potential for practical security applications. This method gives impetus to the image encryption of the visual information and paves the way for the CNI-informed applications of speckle correlography.","PeriodicalId":223078,"journal":{"name":"Advanced Photonics Nexus","volume":" 6","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141828516","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While most of the work focuses on materials, optical structures, and devices, little attention is paid to the reconstruction algorithm, thus resulting in a common issue: the effectiveness of spectral reconstruction is limited under high-level noise originating from the data acquisition process. Here, we fabricate a computational spectrometer based on a quantum dot (QD) filter array and propose what we believe is a novel algorithm, TKVA (algorithm with Tikhonov and total variation regularization, and the alternating direction method of multipliers), to suppress the impact of noise on spectral recovery. Surprisingly, the new TKVA algorithm gives rise to another advantage, i.e., the spectral accuracy can be enhanced through interpolation of the precalibration data, providing a convenient solution for performance improvement. In addition, the accuracy of spectral recovery is also enhanced via the interpolation, highlighting its superiority in spectral reconstruction. As a result, the QD spectrometer using the TKVA algorithm shows supreme spectral recovery accuracy compared to the traditional algorithms for complex and broad spectra, a spectral accuracy as low as 0.1 nm, and a spectral resolution of 2 nm in the range of 400 to 800 nm. The new reconstruction algorithm can be applied in various computational spectrometers, facilitating the development of this kind of equipment.","PeriodicalId":223078,"journal":{"name":"Advanced Photonics Nexus","volume":"3 04","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.spiedigitallibrary.org/journals/advanced-photonics-nexus/volume-3/issue-4/046009/Robust-spectral-reconstruction-algorithm-enables-quantum-dot-spectrometers-with-subnanometer/10.1117/1.APN.3.4.046009.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147914302","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
