SAS Early Career Interest Group 

 

About Us:

In 2021, the Society for Applied Spectroscopy (SAS) created an Early Career Interest Group (ECIG) and membership category to serve scientists who have graduated with their final degree (bachelors, masters, or doctorate) within the last ten years. The SAS-ECIG is a diverse committee that is dedicated to providing members with a unique experience to help promote and succeed in their career. Together, we aim to support the professional development of early career scientists through award schemes as well as opportunities in leadership, outreach, networking, mentorship, volunteering, formal certification, and employment.

 

Mission Statement:

Exploring Metabolism: Advanced Insights from Photothermal Infrared Microscopy in Biomedical Research

Abstract:

Understanding metabolic processes is crucial for unraveling intricate biological systems. Investigating these processes provides key insights into cellular functions and their dysregulation across various pathologies. Optical imaging techniques, recognized for their superior resolution and specificity, have significantly advanced this field. Among these, vibrational spectroscopic imaging, particularly mid-infrared photothermal (MIP) imaging, stands out as a powerful tool. This label-free technique captures inherent chemical bond vibrations and utilizes photothermal effects induced by mid-infrared (IR) absorption with a visible beam, thus enhancing spatial resolution in far-field mid-IR imaging. It enables sub-micrometer and depth-resolved visualization of living cells and entire organisms. In this presentation, I will discuss the recent advancements in MIP technology, with a particular emphasis on its application to metabolic research. I will highlight our studies in areas such as microbiology, stem cell research, and neurodegeneration, demonstrating the transformative potential of MIP technology in paving new paths for groundbreaking discoveries in metabolic research.

Self-Modeling Curve Resolution Analysis of Raman Spectra from Mixed Deuterated and Protiated Phospholipid Membranes Reveals Isotopically-Segregated Lipid Domains

Abstract:

Deuterated phospholipids are often employed as “non-perturbing” probes of phospholipid membrane structure in vibrational spectroscopy, allowing resolution of frequency-shifted vibrational modes of deuterated phospholipids in mixed-phospholipid membranes. Calorimetry of deuterated-phospholipid vesicles has shown lower-temperature melting transitions and reduced cooperative melting, in deuterated lipids. A study combining infrared spectroscopy and molecular-dynamics simulations shows evidence that incorporation of deuterated phospholipids into protiated lipid membranes induces phase-segregation, where two distinct melting transitions occur in calorimetric thermograms. In the current work, phase segregation in individual, mixed deuterated and protiated lipid vesicles is investigated by Raman microscopy. Raman spectra of mixed-lipid vesicles, collected as a function of deuterated-lipid fraction, were examined by self-modeling curve resolution, allowing model-free resolution of spectral vectors and corresponding temperature-dependent composition profiles. The resulting spectral vectors point to microdomain formation in the membrane, indicated by Raman modes in CH- and CD-stretching regions. As the CD/CH composition is varied, domain size increases linearly with deuterated lipid fraction. Deuterated and non-deuterated lipid segregation allows short-range vibrational coupling within pure-lipid domains.  To study the impact of dipolar coupling on lipid-domain structure, mixed-lipid vesicles were monitored as a function of temperature. Two distinct melting transitions are observed, and the melting-transition-temperature of each lipid is shifted from that of a pure sample. Interestingly, dipolar coupling is observed in each lipid type until completion of the phase transition, suggesting that coupling between neighboring phospholipids may contribute to phase-separation during the transition. These results question the assumption that deuterated phospholipids are non-perturbing and suggest caution using deuterated phospholipids in membrane research.
