Acceleration of Biomolecule Enrichment and Detection with Rotationally Motorized Opto-Plasmonic Microsensors and the Working Mechanism.
TLDR
How the controlled mechanical rotation (or rotary motorization) of designed opto-plasmonic microsensors can substantially and robustly accelerate the enrichment and detection speed of deoxyribonucleic acid (DNA) with retained high sensitivity is reported.
Bioinspired Design of Graphene‐Based Materials
It can be difficult to know where to begin when considering the research opportunities of a material with such outstanding potential as graphene. When searching for a “killer application,” the
Exopolysaccharides directed embellishment of diatoms triggered on plastics and other marine litter
TLDR
A proof-of-concept model is developed to successfully deliver a message concerning benefit of using different diatom species to identify the substrates that adhere to diatoms strongly and was mainly analyzed by scanning electron microscope.
The Probable Mechanism for Silicon Capture by Diatom Algae: Assimilation of Polycarbonic Acids with Diatoms—Is Endocytosis a Key Stage in Building of Siliceous Frustules?
TLDR
Partial condensation of silicic acid is a plausible first stage of silicon assimilation and points to the ability of diatoms to recognize substances that bear four acidic groups and to include them into siliceous frustules.
Deep data analytics for genetic engineering of diatoms linking genotype to phenotype via machine learning
Genome engineering for materials synthesis is a promising avenue for manufacturing materials with unique properties under ambient conditions. Biomineralization in diatoms, unicellular algae that use

Characterization of Silica Nanoporous Structures of Some Diatom Frustules and their Applications
Diatoms are unicellular algae that belonging to the class Bacillariophyceae. They inhabit nearly all aquatic environments from marine to freshwater and moist habitats. These organisms create highly
Nanoporous Silica of Some Egyptian Diatom Frustules as a Promising Natural Material
Diatoms are a large unique group of unicellular microalgae with a significant ornamented cell wall made of hydrated silica, which is called "frustule". Their ornamented siliceous shells are usually
Diatom frustules protect DNA from ultraviolet light
TLDR
It is shown that reflection of ultraviolet light by nanostructured silica can protect the deoxyribonucleic acid (DNA) in the algal cells, and that this may be an evolutionary cause for the formation of glass cages.
Light-induced dynamic structural color by intracellular 3D photonic crystals in brown algae
TLDR
The results suggest that these complex intracellular natural photonic crystals are responsive to environmental conditions, changing their packing structure reversibly, and have the potential to manipulate light for roles beyond visual signaling.
Ocean acidification conditions increase resilience of marine diatoms
TLDR
It is demonstrated that resilience of diatoms increases significantly in ocean acidification conditions, and this stress test framework can be extended to evaluate and predict how various climate change associated stressors may impact microbial community resilience.
Structure-based optics of centric diatom frustules: modulation of the in vivo light field for efficient diatom photosynthesis.
TLDR
It is demonstrated that the optical properties of the frustule valves in water affect light harvesting and photosynthesis in live cells of centric diatoms (Coscinodiscus granii) and alter the cellular light field with implications on diatom photobiology.
The UV filtering potential of drop-casted layers of frustules of three diatom species
TLDR
Characterization of the UV protection performance of layers of diatoms frustules is of central relevance for their potential use as innovative bio-based UV filters and the relative importance of crystal structure properties, nanostructure and quantity of material on the spectral properties of diatom layers is discussed.
