Consequently, the development of sensitive, non-invasive, and cost-effective diagnostic approaches is a major clinical priority. Metabolomics, the comprehensive profiling of small-molecule metabolites, has emerged as a powerful tool for uncovering cancer-associated metabolic alterations, providing insights into tumor biology and facilitating the discovery of novel biomarkers for accurate diagnosis and disease monitoring. Among biological matrices, saliva is a promising diagnostic biofluid because it can be collected non-invasively, is simple to obtain, and reflects systemic and local metabolic changes. Recent studies have demonstrated its potential for detecting various cancers, including lung cancer, highlighting its value for biomarker-based early diagnosis.<sup>2,3</sup> In this study, a novel thin-film microextraction (TFME) technique integrated with liquid chromatography-tandem mass spectrometry (LC-MS/MS) is introduced for the rapid, selective, and reproducible extraction of salivary metabolites. The developed TFME approach offers high throughput, reduced solvent consumption, and enhanced analytical performance, enabling the identification and quantification of key metabolic biomarkers associated with lung cancer.

NTD sensor systems, which are prepared to be more protected by the presence of the polymer on the inner surface of the needle, have a longer service life.<sup>2</sup> For this purpose, NTD systems can be prepared using many different types of polymers.In addition, the surface area is significantly increased by coating it onto a cylindrical outer surface. This significantly increases the sensitivity of the method. Breath analysis has become quite popular over the years.<sup>3</sup> These analyses offer advantages such as ease of use and rapid diagnosis, particularly in crucial areas such as early-stage disease diagnosis, and can be performed without causing any pain to the patient due to their non-invasive nature.<sup>4</sup> Additionally, breath samples, which contain less interfering matrix than other biological samples, allow for highly sensitive analyses. Furthermore, due to the very low concentrations of VOCs in breath, more sensitive analytical techniques are needed for these analyses. In this context, the study investigated the applicability of laboratory-developed NTD sensor systems to synthetic breath samples.
