This design enhances light scattering, particularly lateral illumination, compared to configurations without an air gap.

Unlike many other fibre optic photonic devices, the iCARP devices are placed parallel to the target tissue of interest rather than being embedded within it.Ī) The iCarP's structure comprises a tapered optical fiber (TOF) and a waveguiding patch substrate, separated by an air gap. The iCarP uses the diffraction of the optical fibre, with dual refractions in the air gap, and reflections inside the patch to achieve a bulb-like illumination that can be guided towards the target organ or tissue. The device is composed of a refractive polyester patch, a removable tapered optical fibre, and a micrometre scale air gap between these two components. Researchers have now created a flexible and biodegradable photonic device, known as iCarP, that can illuminate internal tissues and organs within the human body. Fibre optic devices can also be integrated within tissues for deeper illumination targeting. This means that they can be used in a number of clinical areas, including laser-induced thermotherapy, optogenetics, and temperature and pressure sensing. There’s an interest in fibre-optic-based devices because they can be placed within a target location of the body to illuminate a specific area. Fibre optics are also more versatile than other devices, not only because they are a very established technology in the communication space, but they can also be integrated easily with endoscopes and used with magnetic resonance imaging (MRI). Optical fibre-based devices are another option for more precise and high-power waveguiding operations and can be made nowadays from clinically approved biocompatible materials. In these areas, the energy-transferring efficiency or the light penetration efficiency of the device determines its illumination intensity. Common examples include near-field-communication (NFC)-based light-emitting-diodes and upconversion nanoparticles. There have been a number of studies that have come out with a range of implantable light-emitting components. Current Implantable Light Sources for In-vivo Phototherapy When it comes to trying to deliver light energy to deep tissue and organ targets, it is hard for light to penetrate so far into the body because the light particles are absorbed by the surrounding tissues, the photons get scattered by biological media, and the autofluorescence of nearby organs and organelles can interfere with the procedure. This is especially true when trying to create a large area illumination into deep tissue targets, so if these factors can be controlled to a greater degree, then it could improve the safety and efficacy of phototherapy procedures, as well as widen the application scope in where they are used. These strategies need to be versatile and adaptable, as the depth, area, wavelength, and power required can vary greatly depending on the specific clinical application. In simpler terms, 'in-vivo illumination strategies' refer to the methods used to deliver light energy directly to the target area within the body.
In a lot of phototherapy procedures, the in-vivo illumination strategies used don’t have a depth, area, wavelength, and power to be used universally across different clinical areas. One of the key areas that has the potential to be improved is the precision, versatility, and controllability in delivering the light energy to the target. Overcoming Obstacles: The Role of In-Vivo Illumination Strategies Despite their widespread use, and like many things that are used today, there is always some room for improvement. Phototherapies are used within a wide range of clinical settings and are a common technique in hospitals.

Phototherapy is a medical technique that allows for the illumination of organs and tissues and can be used in a range of clinical settings, including in optical diagnostic tests, laser surgery, for treating the skin of newborn babies, and for any other procedure where light-activated therapies create a unique light microenvironment on a target of interest. The Promise and Challenges of Phototherapy
What if we could treat deep tissue diseases more effectively, safely, and versatilely? This is not a distant dream but a reality brought closer by a new device called iCarP. But how do we overcome the challenges of delivering light energy to deep tissues? The answer might lie in a new device called iCarP. This is the promise of phototherapy, a medical technique that uses light to treat a variety of conditions. Imagine a world where the treatment of deep tissue diseases is not only more effective but also safer and more versatile.
