La position A healthcare pioneer and the industry’s global leader in in-vitro diagnostics, the Diagnostics Division pushes boundaries and challenges the status quo to redefine what’s possible. Our commitment to research and development means we can bring to the market integrated solutions in diagnostic testing, laboratory efficiency, healthcare digitalization, and decision support tools and software. Our products deliver increasingly precise information to help save lives, prevent or control the risk of infection, and monitor treatment effectiveness.

At Sensor and Reagent Development BGE , we are at the forefront of innovation in the healthcare industry. Banking on the technical expertise and know-how of our skilled and dedicated team of scientists and engineers, we design and develop sensors and reagents for blood gas and electrolyte (BGE) analyzers. Our products are essential for accurate and reliable patient diagnostics, impacting lives every day. The Opportunity In this internship, you will drive an exploratory feasibility project to evaluate novel oxygen scavenging strategies for next-generation blood gas reagent formulations.

The project focuses on different innovative pathways such as small organic molecule scavengers, storage-stable enzymatic systems, and functional multilayer packaging foils.

include:

• Organic Scavenger Screening & Electrochemistry: Identify and evaluate small organic molecules (e.g., food additives, antioxidants) to determine oxygen depletion kinetics while analyzing electrochemical behavior to minimize potential sensor interference.
• Enzymatic Scavenger Systems: Assess and validate enzyme-based systems for their feasibility and performance as effective oxygen scavengers.
• Functional Packaging & Materials Evaluation: Investigate active scavenging polymer laminates and pouch foils, conducting thorough leachables and extractables testing to safeguard sensor and reagent stability.
• Analytical Testing & Characterization: Apply advanced electrochemical, spectroscopic, and chromatographic methods to measure oxygen consumption rates and characterize matrix interactions.
• Data Analysis & Documentation: Synthesize experimental results, assess formulation and material viability, and present clear technical summaries and recommendations to the cross-functional R&D team. Who You Are
• You are currently enrolled in, or have graduated from, a Master’s degree program (or equivalent advanced studies) in Chemistry, Organic Chemistry, Biochemistry, Chemical Engineering, Materials Science , or a related field within the last 12 months prior to your start date.
• You are eager to gain practical industry experience in a dynamic laboratory setting. Furthermore, You have:
• Strong theoretical and practical foundation in organic chemistry and wet-lab chemical formulation (Required).
• Sound knowledge of enzymes, enzyme kinetics, and biochemical reaction mechanisms (Required).
• High degree of self-organization, analytical problem-solving skills, and a structured approach to experimental design (Required).
• Excellent communication and teamwork abilities in English (Required).
• Interest or experience in electrochemistry (e.g., oxidation potentials, electrode interactions) or analytical techniques (e.g., UV/Vis spectrophotometry, fluorescence assays) (Preferred).
• Basic understanding of or curiosity about packaging materials, active foils, and leachables/extractables testing (Preferred).
