Microbial production of textile grade pigments

African Journal of Microbiology Research, 2017
Biological pigments or biochromes are substances produced by living organisms and have a color  resulting from selective color absorption. A total of 37 isolates of Actinomycetes and 2 bacteria were isolated from 26 different soil samples collected from different habitats of Kerala. The isolates were screened for pigment production.

DENTA: A Dual Enzymatic Nanoagent for Self‐Activating Tooth Whitening and Biofilm Disruption

Advanced Functional Materials, EarlyView.
The nanoapatite with dual enzymes (DENTA) accumulates in dentinal tubules, reducing hypersensitivity caused by dental nerve exposure and facilitating continuous ROS generation through salivary glucose for effective, long‐term whitening. The dentin structures remain non‐destructive due to the low concentration of ROS, demonstrating excellent cell ...
