Chitin‐Derived Carbon‐Metal Functional Materials

open access: yesAdvanced Functional Materials, EarlyView.
Functional carbon materials are synthesized from combination of biopolymer (chitin) and iron precursors. The resultant material exhibits superior surface area and adsorptive properties compared to carbon materials synthesized directly from pure chitin.

Insect frass fertilizer upregulates maize defence genes and resistance against an invasive herbivore pest

open access: yesScientific Reports
The black soldier fly frass fertilizer (BSFFF) has gained global attention as a multipurpose input for soil fertilization and pest and disease management. However, there are limited studies that have examined its effects on insect pest resistance and the

An inexpensive and portable microvolumeter for rapid evaluation of biological samples

open access: yesBioTechniques, 2010
We describe an improved microvolumeter (MVM) for rapidly measuring volumes of small biological samples, including live zooplankton, embryos, and small animals and organs.

Microfluidic Nano‐Assembly of Red‐Blood‐Cell (RBC) Lipids and Components for Engineering Extracellular Vesicles

open access: yesAdvanced Healthcare Materials, EarlyView.
Engineered red blood cell‐derived extracellular vesicles (eRBCEVs) are synthesized via controlled microfluidic assembly from native RBC lipids, enabling tunable encapsulation of proteins, nucleic acids, nanoparticles, and viral vectors. The platform demonstrates reproducible nanoscale architecture, preserved membrane composition, and functional cargo ...

Characterization and bioassay of indigenous isolates of the fall armyworm, Spodoptera frugiperda nucleopolyhedrovirus in India

open access: yesEgyptian Journal of Biological Pest Control
Background Maize fall armyworm, Spodoptera frugiperda (J. E. Smith) (Lepidoptera: Noctuidae), is a highly migratory polyphagous insect pest that has posed itself as a very threatened insect invaded India since May 2018 and devastated the maize crop. This

Development of mitochondrial DNA cytochrome c oxidase subunit I primer sets to construct DNA barcoding library using next-generation sequencing [PDF]

open access: yesBiodiversity Data Journal
Insects are one of the most diverse eukaryotic groups on the planet, with one million or more species present, including those yet undescribed. The DNA barcoding system has been developed, which has aided in the identification of cryptic species and ...

Ionic Gating of Liquid‐Crystal‐Like Pteridine Assemblies Enables Tunable Light Scattering

open access: yesAdvanced Materials, EarlyView.
Tunable optical properties emerge through developmentally regulated ionic gating, which transforms disordered, ultraviolet (UV)‐absorbing organelles into concentrically ordered, liquid‐crystal‐like light scatterers. By integrating analyses of pteridine composition, potassium‐dependent assembly, hierarchical ultrastructure, and optical behavior, the ...

Multi‐Biomimetic Structural Colors Inspired by Pearls and Bird Feathers

open access: yesAdvanced Materials, EarlyView.
A dual‐biomimetic strategy mimicking pearls and bird feathers is proposed to construct full‐gamut structural colors. By integrating a non‐strictly periodic inorganic multilayer architecture with tunable light absorbers, this facile approach circumvents the complex fabrication of traditional 1D photonic crystals, offering immense potential for cosmetics,
