Biophotonics probes and sensors integration (BioProbe)
About
BioProbe is a collaborative initiative by the biophotonics team at Tyndall, focusing on the design and integration of miniature biophotonics probes and sensors for prototyping. This project aims to create advanced probes specifically tailored for various biophotonics applications. The design process considers critical aspects to ensure high performance, miniaturisation and precision.
Description
Advancements in biophotonics have opened new frontiers in medical diagnostics, environmental monitoring, and other critical fields. At the forefront of this innovation is the BioProbe initiative, a initiative focuses on the meticulous design and integration of miniature probes and sensors for prototyping, addressing the unique demands of biophotonics applications.
Our team at Tyndall has experience in the design and development of miniature probes for wide range biophotonics technologies including time domain diffuse reflectance spectroscopy, fluorescence lifetime imaging, fluorescence and Raman probes. By leveraging their expertise, the team at Tyndall has developed number of demonstrators showcasing our highly specialized probes technology, that enhance performance at reduced probe footprint, driving forward the capabilities of biophotonic technology.
Technical specifications:
Probes technologies: Fluorescence, FLIM, Diffuse reflectance, time domain diffuse reflectance probes, Raman probes.
Geometry: Contact and non-contact geometry
Components for integration: prisms, lenses, filters, 3D printed mounts, fiber and fiber optics, mirrors, microcameras.
Case study:
Case study 1: we designed and developed chip on tip Fluorescence lifetime endoscope and packed in our lab. This demonstrates our capabilities to integrate time resolved SPAD arrays, lenses, filters, casing into a FLIM endoscope.
