Long and hollow glassy carbon microfibers were fabricated based on the pyrolysis of a natural product, human hair. The two fabrication steps of carbon microelectromechanical and carbon nanoelectromechanical systems, or C-MEMS and C-NEMS, are: (i) photolithography of a carbon-rich polymer precursor and (ii) pyrolysis of the patterned polymer precursor.

The robust device design of fringing-field electrostatic MEMS actuators results in inherently low squeeze-film damping conditions and long settling times when performing switching operations using conventional step biasing. Real-time switching time improvement with DC-dynamic waveforms reduces the settling time of fringing-field MEMS actuators when transitioning between up-to-down and down-to-up states.

A protocol for a fixed-fixed beam design using a laser Doppler vibrometer (LDV), including the measurement of frequency tuning, modification of tuning capability, and avoidance of device failure and stiction, is presented. The superiority of the LDV method over the network analyzer is demonstrated due to its higher mode capability.
FAQs
Opti-MEM’s low-protein environment can favor the formation and delivery of nucleic acid complexes during transfection. With less serum present, researchers can prepare these complexes in a more controlled setting. This is particularly relevant when plasmid DNA or RNA must reach mammalian cells for gene-expression experiments.
The balanced nutrients and salts in Opti-MEM help maintain mammalian cells while experiments are performed under reduced-serum conditions. That support matters because cells must remain suitable for manipulation, not merely survive handling. Maintaining this consistent environment helps researchers compare gene-expression experiments while limiting differences associated with serum content.
Reduced-serum conditions can reduce serum-related variability in cell-based assays, making the experimental environment more consistent across measurements. This is useful when differences in gene expression or cellular responses need to be attributed to the tested manipulation rather than changing serum contributions. Opti-MEM therefore supports cleaner comparisons during optimization and routine experimental work.
It can serve both as a medium for mammalian cell handling and as a preparation environment for nucleic acid delivery reagents. In plasmid DNA or RNA experiments, this links routine culture conditions with the manipulation step. Using one consistent medium across these activities can help standardize workflows and improve reproducibility.
Applications include routine mammalian cell handling, plasmid DNA transfection, RNA transfection, and optimization of gene-expression experiments. The medium is relevant whenever researchers need cells maintained in a consistent environment while introducing nucleic acids or evaluating expression outcomes. These uses connect day-to-day cell culture with targeted biological manipulation.
The main outcome is a more consistent experimental setting, rather than a guarantee of higher expression. By combining a balanced nutrient and salt environment with reduced serum exposure, Opti-MEM can help limit serum-related variation and support repeatable cell-based measurements. Researchers can use that consistency when interpreting transfection or gene-expression results.
