Riboflavin-Doped DNA Thin Films Topological and Electro-Optical Characteristics

2019 data from Bramaramba Gnapareddy characterizes riboflavin-doped synthetic double-crossover DNA lattices and natural salmon DNA thin films. The dataset includes measurements of atomic force microscopy images, current, absorbance, and photoluminescence to analyze phase transitions and critical doping concentrations.

Use Cases

• Analyze the relationship between riboflavin concentration and current or UV absorbance band measurements in salmon DNA thin films.
• Study photoluminescence intensity trends as a function of varying riboflavin concentration for potential bio-photonic device development.
• Use Fourier transform infrared spectrum data to understand the interaction between riboflavin and DNA molecules.
• Correlate atomic force microscopy image analysis with critical doping concentration to observe structural phase transitions in DNA lattices.

Strengths

• Data includes multiple measurement types: atomic force microscopy, current, absorbance, and photoluminescence.
• Identifies a specific critical doping concentration of riboflavin (~5 mM) for phase transition analysis.
• Research is focused on a specific application area: bio-sensors and bio-photonic devices.

Limitations

• Sample size and number of experimental replicates are unknown.
• Data is from a single study published in 2019, potentially limiting temporal relevance.
• Raw data files, formats, and structured column definitions are not provided.
