Her research activity concerns mainly the development of laser systems for time-resolved spectroscopy and imaging, and their applications in biology and medicine.
In particular, she has developed a system for time-gated fluorescence spectroscopy with picosecond resolution and has applied it to the photophysical characterization of various endogenous (e.g. blepharismin) and exogenous (e.g. hypericin) pigments and photosensitizers (e.g. porphyrins and phthalocyanins) for the photodynamic therapy of tumors (PDT). She has also been engaged in the optimization of therapeutic protocols for PDT. More recently, she has been working on the detection of tumors with time-resolved fluorescence imaging. In particular, she contributed to the development of a portable system and to its clinical application to the diagnosis of skin lesions (by means of the detection of Protoporphyrin IX fluorescence induced by the topical application of 5-aminolevulinic acid, ALA). She has also characterized in the temporal and spectral domains the fluorescence properties of fullerol (water-soluble fullerene derivative) incorporated in human cells, to investigate the intracellular distribution and cytotoxicity of those nanoparticles, that are studied for applications in medicine and other fields.
Since several years ago, her interests include and mostly focus on light propagation in highly diffusive media (“photon migration”), and in particular time-resolved reflectance and transmittance spectroscopy for the non-invasive optical characterization of turbid media, such as biological tissues. In this line, she has contributed to the development of a system for the assessment of the absorption and scattering properties of turbid media. The system is fully automated and operates continuously from 600 and 1100 nm. It is unique at international level and is part of the European Facility “Center for Ultrafast Science and Biomedical Optics” (CUSBO), funded by the EU programs FP5 and FP6. The system allowed - for the first time - the measurement of the absorption and scattering spectra of various biological tissues “in vivo” over a broad spectral range. In particular, she performed the first optical characterization of bone tissue “in vivo” in the red and near infrared, as a first promising step toward the development of a non-invasive optical technique for the diagnosis of osteoporosis. She has also monitored non-invasively physiological changes occurring in breast tissue during the menstrual cycle, of interest for optical mammography.
Using the same instrumentation, within the EU project “Diffruit” (“Diffuse reflectance spectroscopy for the evaluation of fruit and vegetables internal quality”), she has also worked on the first optical characterization of different types of fruits, opening a new field related to the non-destructive evaluation of the internal quality of horticultural products.
Paola Taroni contributed to the development of the first prototype of time-resolved near-infrared oximeter and to its application to the monitoring of hemoglobin content and oxygen saturation in muscle under exercise.
She is also deeply involved in the development and application of time-resolved transmittance imaging techniques, with particular attention to breast cancer detection (optical mammography). Within the EU project “Optimamm”, she contributed to the design and realization of a prototype of optical mammograph operating in the time domain at several (4 to 7) wavelengths in the 637-985 nm range. The instrument, unique at international level, was tested in a clinical trial on 200 patients with malignant and benign lesions and provided information on breast tissue composition and structure that is useful to identify the detected lesions. The mammograph was then further upgraded, extending also the spectral range from 635 to 1060 nm, to increase the sensitivity to collagen content in tissues, and has been applied at the European Institute of Oncology (Milan) in a clinical trial with two-fold aim: i) the optical characterization of malignant and benign breast lesions; ii) the non-invasive optical assessment of breast tissue density, which is a well-known risk factor for developing breast cancer. The study, which has recently ended, has enrolled 218 patients and obtained promising results on both aims.
She coordinates the H2020 project SOLUS – “Smart Optical and Ultrasound Diagnostics of Breast Cancer” (2016-2020), for the development of a multimodal imaging system, combining multi-wavelength time domain diffuse optical tomography, conventional B-mode ultrasound imaging and quantitative shear wave elastography, with the aim of improving the specificity of breast screening and reducing the high number of false positive invasive assessments.
She contributed to the development of a portable instrument for time-resolved diffuse optical spectroscopy in the range of 600-1350 nm, suitable for use in a clinical environment.
She is also involved in the optical characterization of tissue constituents (elastin, thyroglobulin, etc.) of interest for non-invasive medical diagnostics and physiology studies by diffuse optical means.
