Special Issue Information

Dear Colleagues,

In the third millennium, in our advanced technological epoch, striking hygienic and medical cutting-edge progress notwithstanding, microorganisms and non-infectious diseases still threaten human lives. SARS-CoV-2 has knocked thousands of health workers out of action worldwide. Science has also been affected, with studies paused in the majority of cases because data collection on surgical conditions in a pandemic crisis is difficult. Meetings, congresses, and courses have been cancelled or rescheduled as virtual. Meaningful research is necessary in order to compare the impact of diseases that have been affecting humanity from more than a decade (swine flu) to more than a century (tuberculosis). Today, more than ever after our experience with COVID-19, it is necessary to apply science, particularly molecular science, to the research and study of human diseases.

Infrared (IR) and Raman (RS) spectroscopy are used herewith to research human diseases at a molecular level. IR and RS are complementary; contrary to other detection diagnostic optical methods, both allow for a simultaneous analysis of all the components of the human tissues, liquid materials, or single cells, at a molecular level, without any specific preparation of the samples as in histopathology. Specific spectra of the biological molecules can be used to locate characteristic bands called “marker bands” in “fingerprint” regions in order to distinguish the native (healthy) state from the diseased one.

The spectra of biological molecules are sensitive to structural changes induced by the environment of these molecules and various affecting diseases including splachnic cancer (skin, breast, etc.), musculoskeletal neoplasms (benign and malignant bone and soft tissue tumors, and metastatic bone disease), cardiovascular diseases (coronary artery disease, atheromatosis, heart valve disease), diabetes mellitus, amyloidosis, and neurological diseases (Alzheimer and Parkinson). Additionally, since IR and RS are non-destructive, easy, and simple methods that require extremely small amounts of tissue samples for analysis, they can be used intraoperatively for rapid diagnosis of surgical margins after tumor resection surgery.

In the last decade, there has been a plethora of papers devoted to the research and study of many medical applications used to predict abnormalities induced by the disease and its progression as it deteriorates the health of the person. Therefore, we scheduled this Special Issue with the aim of collecting original papers, educative reviews, technical papers, and other forms of scientific communication on the molecular science of human disease.

Due to the high mortality rate, more effective non-invasive diagnostic methods are still needed for lung cancer, the most common cause of cancer-related death worldwide. In this study, the integration of Raman and Fourier-transform infrared spectroscopy with advanced data-fusion techniques is investigated to improve the detection of lung cancer from human blood plasma samples. A high statistical significance was found for important protein-related oscillations, which are crucial for differentiating between lung cancer patients and healthy controls. The use of low-level data fusion and feature selection significantly improved model accuracy and emphasizes the importance of structural protein changes in cancer detection. Although other biomolecules such as carbohydrates and nucleic acids also contributed, proteins proved to be the decisive markers found using this technique. This research highlights the power of these combined spectroscopic methods to develop a non-invasive diagnostic tool for discriminating lung cancer from healthy state, with the potential to extend such studies to a variety of other diseases.

Raman spectroscopy and Fourier transform infrared (FTIR) spectroscopy are powerful analytical techniques widely used separately in different fields of study. Integrating these two powerful spectroscopic techniques into one device represents a groundbreaking advance in multimodal imaging. This new combination which merges the molecular vibrational information from Raman spectroscopy with the ability of FTIR to study polar bonds, creates a unique and complete analytical tool. Through a detailed examination of the microscope’s operation and case studies, this article illustrates how this integrated analytical instrument can provide more thorough and accurate analysis than traditional methods, potentially revolutionising analytical sample characterisation. This article aims to present the features and possible uses of a unified instrument merging FTIR and Raman spectroscopy for multimodal imaging. It particularly focuses on the technological progress and collaborative benefits of these two spectroscopic techniques within the microscope system. By emphasising this approach’s unique benefits and improved analytical capabilities, the authors aim to illustrate its applicability in diverse scientific and industrial sectors. Full article
