Role of bio-nanotemplates on the lasing behavior of LDS 821 dye

The inferences obtained from a brief investigation on the lasing characteristics of near infrared hemicyanine laser dye LDS 821 in different bio-nanotemplates are reported here. Solution state lasing behavior of LDS 821 in deoxyribonucleic acid (DNA) -surfactant complex and in lysozyme amyloid fibrils are studied. Equally spaced well resolved resonant modes are observed for LDS 821 dye in DNA-surfactant complex at a very low pump power as compared to dye alone sample under similar conditions. The lasing threshold of the dye could be further decreased on incorporation with lysozyme amyloid fibrils. The lasing spectrums of the dye in lysozyme amyloid fibrils at different pump powers are irregular in shape due to random lasing. Studies show that DNACTMA and lysozyme amyloid fibrils can be used as a potential bio-nanotemplate for the fabrication of biolasers.

Automated summary

The lasing characteristics of near infrared hemicyanine laser dye LDS 821 in different bio-nanotemplates were studied, showing promising results in DNA-surfactant complex and lysozyme amyloid fibrils. The well-resolved resonant modes and lower lasing threshold observed in these bio-nanotemplates suggest their potential use in biolaser fabrication. Random lasing behavior in lysozyme amyloid fibrils indicates the complexity of the lasing process in this system.
