“…Utilizing phage display techniques, an array of proteins as well as polypeptides boasting diverse bio-functionalities can be systematically and meticulously showcased on the phage capsids' surface [83]. Driven by their stability, biosafety, and availability attributes, phages have currently developed as multipurpose means with a plethora of biological medical uses [84][85][86][87][88]. A groundbreaking phage-derived biolaser tailored for bio-detection has emerged, featuring the utilization of the M13 phage-a filamentous phage characterized by its rod-like architecture, having a length of 900 nm as well as a diameter of 7 nm [43].…”

The rapid progress in the fields of biomedical and biological photonic sciences has given rise to a substantial demand for biological photonic structures capable of interacting with living systems. These structures are expected to facilitate precise manipulation of incident light at small scales, enabling the detection of sensitive biological signals and the achievement of highly accurate cell structural imaging. The concept of designing biological photonic devices using innate biomaterials, particularly natural entities such as cells, viruses, and organs, has gained prominence. These innovative devices offer the capability of multimodal light manipulation at specific sites, enhancing biological compatibility while minimizing disruptions to the delicate biological microenvironment. This article delves into recent advancements within the realm of biological photonic devices, with a dedicated focus on their applications in bio-imaging and -diagnosis. The central theme revolves around devices derived from biological entities possessing the requisite optical properties, biocompatibility, biofunctionality, and the ability to induce biological effects. These devices encompass a diverse range of optical functionalities, including light generation, transportation, and modulation, all of which play pivotal roles in bio-detection and imaging, thereby contributing notably to the advancement of these fields. The potential future directions and opportunities for the enhancement of biological photonic devices were outlined.

The rapid development of biophotonics and biomedical sciences makes a high demand on photonic structures to be interfaced with biological systems that are capable of manipulating light at small scales for sensitive detection of biological signals and precise imaging of cellular structures. However, conventional photonic structures based on artificial materials (either inorganic or toxic organic) inevitably show incompatibility and invasiveness when interfacing with biological systems. The design of biophotonic probes from the abundant natural materials, particularly biological entities such as virus, cells and tissues, with the capability of multifunctional light manipulation at target sites greatly increases the biocompatibility and minimizes the invasiveness to biological microenvironment. In this review, advances in biophotonic probes for bio-detection and imaging are reviewed. We emphatically and systematically describe biological entities-based photonic probes that offer appropriate optical properties, biocompatibility, and biodegradability with different optical functions from light generation, to light transportation and light modulation. Three representative biophotonic probes, i.e., biological lasers, cell-based biophotonic waveguides and bio-microlenses, are reviewed with applications for bio-detection and imaging. Finally, perspectives on future opportunities and potential improvements of biophotonic probes are also provided.
