Salinas, Leo Tornes, Christopher Solís*  \nDepartment of Health, Nutrition, and Food Sciences, Florida State University, Tallahassee, Florida, United States of America  \n* [csolis@fsu.edu](csolis@fsu.edu)  \nAbstract  \nEfficient inventory management remains a persistent challenge in research settings, where productivity and budget control are tightly linked to accurate tracking of consumables, reagents, and equipment for decision-making and successful research project execution. Many laboratories still rely on traditional methods, including handwritten logs or static spreadsheets, which are prone to human error and can result in stockouts, over-ordering, and inaccurate forecasting. Moreover, existing inventory systems often fall short in balancing affordability, convenience, and functionality.  \nHere, the Laboratory Inventory Management Engine (LIME) is introduced as a system designed to bridge these deficiencies by leveraging accessible tools like in-thecloud spreadsheet files and mobile devices. LIME uses a smartphone app to enable real time updates to the inventory log by scanning consumables QR codes and barcodes. The system allows inputting new items to be classified in predetermined catalog lists (e.g. , 4º fridge, chemicals, antibodies, etc.) . This dual smartphone and spreadsheet inventory prototype is anticipated to improve the operational efficiency of small academic research laboratories and early-stage startups to benefit their bottom lines.  \nIntroduction  \nMaintaining a laboratory inventory is an important but often underestimated task in research—yet it plays a critical role in the efficiency of labor. Inaccuracies in inventory tracking can lead to mistrials, delays, financial loss, and compromised data integrity [ 1] . Developing a reliable and efficient inventory system is essential for ensuring smooth experimental operations and maintaining optimal research quality.  \nPLOS One | [https://doi.org/10.1371/journal.pone.0336412](https://doi.org/10.1371/journal.pone.0336412) May 22, 2026 1 / 7  \ncollection and analysis, decision to publish, or preparation of the manuscript.  \nCompeting interests: The authors have declared that no competing interests exist.  \nMany laboratories track inventory in one of three ways, either through Excel® spreadsheets and Google Sheets® , sheets of paper, or via paid subscriptions to laboratory information management systems (LIMS) [2] .
