Spectroscopy Beyond the Laboratory: Portable NIR Technologies Enabling Global Analytical Impact

Portable near-infrared (NIR) spectroscopy is transforming molecular analysis by enabling rapid, on-site measurements in environments far beyond conventional laboratories. Advances in miniaturized instrumentation, combined with powerful chemometric and data-driven approaches, now allow reliable molecular information to be obtained directly in the field, at production sites, or at the point of need. This presentation illustrates how portable NIR systems are becoming essential analytical tools across diverse disciplines.
A particular focus is placed on applications where accessibility, speed, and robustness are critical. Examples include food quality assessment, detection of counterfeit pharmaceuticals, environmental screening, and emerging diagnostic strategies. Case studies demonstrate how handheld and field-deployable NIR devices provide actionable results for tasks such as microplastic detection or rapid material fingerprinting, offering significant advantages in resource-limited or remote settings.
Beyond practical applications, the talk discusses the inherent strengths of NIR spectroscopy—its non-destructive measurement, minimal sample preparation, and suitability for complex matrices—while also addressing current challenges. Future perspectives include the integration of quantum chemical modeling, artificial intelligence, and multimodal spectroscopic concepts to further enhance analytical performance.
Overall, the presentation highlights how portable NIR technologies are expanding global access to high-quality molecular sensing and supporting scientific and societal needs in ways previously restricted to fully equipped laboratory environments.
