Lithographically defined polyimide templates were prepared using microfabrication techniques. The templates consist of high aspect ratio pores that were formed by deep plasma etching. Different metals are electrodeposited into the pores, and then the template is removed to allow the metallic rods (particles) to be released into solution. The striping pattern of metals on the particles is used to optically identify the particles. Particles range in size from 0.6 mum in diameter by 7.7 mum in length to 4.2 mum by 27 mum in length. These particles have been evaluated in a multiplexed DNA hybridization assay.

Cellulose nanofibers (CNFs) have gained increasing attention due to their robust mechanical properties, favorable biocompatibility, and facile surface modification. However, green and recyclable CNF production remains challenging. Herein, a green, low-cost and room-temperature strategy was developed to exfoliate CNFs using deep eutectic solvents.

The ultrafine MoO powders were prepared by the combination of centrifugal spray drying and calcination in this work. The thermal decomposition behavior of the spherical precursor was studied. The phase constituents, morphologies, particle size, and specific surface areas of MoO powders were characterized at different temperatures.

(Eu[PTC])(Eu[TREN-1,2-HOPO]) inorganic-organic hybrid nanoparticles (IOH-NPs) contain Eu, tris[(1-hydroxy-2-oxo-1,2-dihydropyridine-6-carboxamido)ethyl]amine (TREN-1,2-HOPO) and perylene-3,4,9,10-tetracarboxylate (PTC). The IOH-NPs are prepared in water and exhibit a rod-type shape, with a length of 60 nm and a diameter of 5 nm. Particle size and chemical composition are examined by different methods (SEM, DLS, FT-IR, TG, C/H/N analysis).

Granular hydrogels are injectable and inherently porous biomaterials assembled through the packing of microparticles. These particles typically have a symmetric and spherical shape. However, recent studies have shown that asymmetric particles with high aspect ratios, such as fibers and rods, can significantly improve the mechanics, structure, and cell-guidance ability of granular hydrogels.

The cellular interior is a spatially complex environment shaped by non-trivial stochastic and biophysical processes. Within this complexity, spatial organizational principles-also called spatial phenotypes-often emerge with functional implications. However, identifying and quantifying these phenotypes in the stochastic intracellular environment is challenging.
