ÌÇÐÄVlog

Biomedical Engineering Laboratory

The Biomedical Engineering (BME) laboratory at ÌÇÐÄVlog (ÌÇÐÄVlog) is equipped with a comprehensive suite of biomaterials, molecular biology, tissue engineering, analytical and cell culture instrumentation that supports both instructional laboratories and research activities. The available infrastructure enables alignment with ABET student outcomes, including the ability to design and conduct experiments, analyze and interpret data, and function effectively in multidisciplinary environments. The laboratory supports courses spanning biomaterials, bioinstrumentation, stem cell engineering, and molecular and cellular engineering, while also facilitating undergraduate research and capstone design projects.

Instrumentation Capabilities and Technical Functions

The ÌÇÐÄVlog-BME laboratory houses instrumentation that supports controlled sample preparation, biological analysis, and advanced characterization:

• Sample Preparation and Processing: Vacuum heating and drying ovens provide temperature-controlled, reduced-pressure environments for solvent removal and biomaterial conditioning, minimizing thermal degradation. Digital hotplate stirrers enable precise thermal and mixing control for solution preparation, polymer synthesis, and reagent formulation. The Eppendorf Centrifuge 5425 R supports high-speed, temperature-controlled centrifugation (up to ~21,000 × g), enabling efficient separation of nanoparticles, cellular components, nucleic acids, and proteins.
  
  
• Sterilization and Containment: Autoclaves provide validated sterilization cycles using saturated steam under pressure, ensuring decontamination of biological waste and preparation of sterile media. Biosafety cabinets (Class II) maintain HEPA-filtered laminar airflow to ensure aseptic handling of cell cultures and biohazardous materials. Fume hoods provide chemical safety through controlled ventilation and exhaust of hazardous vapors.
  
  
• Cell Culture and Biological Systems: CO2 incubators maintain physiologically relevant conditions (37°C, 5% CO2, >90% humidity) for mammalian cell culture. Automated cell counters enable rapid quantification of cell density and viability using trypan blue exclusion or fluorescence-based assays. Refrigeration and freezing systems (4°C and −20°C) ensure proper storage of reagents and biological samples.
  
  
• Analytical and Molecular Characterization: The Cary 670 FTIR Spectrometer provides Fourier-transform infrared spectroscopy for identification of chemical bonds and functional groups in biomaterials, polymers, and biological samples. The AriaMx Real-Time PCR System enables quantitative amplification of nucleic acids, supporting gene expression analysis, pathogen detection, and validation of engineered biological systems. Flow cytometry systems allow high-throughput, multiparametric analysis of cell populations based on size, granularity, and fluorescence-tagged biomarkers.
  
  
• General Laboratory Support Systems: Ultrapure water systems produce Type I water (18.2 MΩ·cm), essential for reproducible molecular biology and analytical procedures. Optical microscopes support bright-field imaging for cell morphology assessment, histological observation, and material surface evaluation.

Curricular Integration

The laboratory infrastructure is systematically integrated across the BME curriculum to support progressive skill development.

Undergraduate Courses

At the undergraduate level, instrumentation is incorporated into structured laboratory modules that emphasize foundational competencies:

• Biomaterials Laboratory: Students utilize FTIR spectroscopy to characterize polymer composition and degradation, and hotplate stirrers for hydrogel synthesis.
• Cell and Tissue Engineering Laboratory: CO2 incubators, biosafety cabinets, and automated cell counters are used for sterile technique, cell seeding, and viability analysis.
• Bioinstrumentation Laboratory: Students gain exposure to data acquisition and analysis, including signal interpretation from analytical instruments.
• Molecular Bioengineering Laboratory: The real-time PCR system is introduced for DNA amplification and gene expression studies, with emphasis on experimental design and quantitative analysis.
• Transport Phenomena and Bioprocessing Labs: Centrifugation and fluid handling systems are used to study mass transport and separation processes.Ìý

These courses emphasize ABET outcomes related to experimental design, data analysis, and application of engineering principles to biological systems.

Graduate Courses

Graduate-level courses leverage the full capabilities of the instrumentation for advanced experimentation and independent inquiry:

• Advanced Biomaterials Characterization: FTIR analysis is applied to investigate molecular interactions, crosslinking, and degradation kinetics of biomaterials.
• Advanced Cell Engineering: Flow cytometry is used for immunophenotyping, apoptosis assays, and stem cell characterization.
• Molecular Biotechnology: Real-time PCR supports quantitative gene expression analysis, primer design, and validation of genetic modifications.
• Quantitative Biomedical Analysis: Students integrate data from multiple instruments to develop predictive models and validate hypotheses.

Graduate instruction emphasizes experimental rigor, reproducibility, and integration of multidisciplinary techniques.

Undergraduate Research and Experiential Learning

The laboratory plays a central role in supporting undergraduate research, a key component of the program’s educational objectives. Students engage in faculty-mentored projects and independent study, utilizing advanced instrumentation typically reserved for graduate-level work.

Examples of undergraduate research applications include:

• Biomaterial synthesis and characterization using FTIR spectroscopy.
• Cell viability and proliferation studies using automated cell counters and microscopy.
• Gene expression analysis using real-time PCR.
• Cell population analysis using flow cytometry.

Students are trained in experimental design, statistical analysis, and technical communication, often culminating in senior capstone design projects, conference presentations, or peer-reviewed publications.

Alignment with ABET Outcomes

The integration of this instrumentation directly supports ABET student outcomes, including:

• Experimentation and Data Analysis: Students design and conduct experiments using modern engineering tools and interpret complex datasets.
• Problem Solving: Laboratory experiences require the application of engineering, biology, and chemistry principles to solve open-ended problems.
• Communication: Students document and present findings in formal lab reports and research presentations.
• Ethics and Safety: Training in biosafety, chemical safety, and responsible conduct of research is embedded across all laboratory courses.Ìý

The Biomedical Engineering laboratory at ÌÇÐÄVlog provides a robust, modern environment that supports both instructional and research objectives. Its comprehensive instrumentation enables scaffolded learning from foundational undergraduate laboratories to advanced graduate research. By integrating hands-on experimentation with theoretical instruction, the laboratory ensures that students are well-prepared to meet the technical and professional demands of the biomedical engineering field.
