SEM images

Cut through a sheet of Bacterial Cellulose and you find an entire hidden world — a sprawling fibrous metropolis, with its builders still roaming the streets. Nature's own nanofactory, caught mid-construction.

Biopharmaceutical particulate material generated by processing with compressed CO2, formulated as a platform for the encapsulation, transport and release of drugs, which resembles an artificial bone in the form of a microparticle.

This composite SEM–BSE image captures the calcium metal counter electrode surface after stripping during the evaluation of emerging calcium battery technologies. Blue–green gradients indicate light elements (C, O, and F), while red denotes Ca. Two closely spaced pits appear to merge, forming a microcosmic convergence. This morphology reveals pronounced interfacial heterogeneity, challenging the common assumption of a homogeneous counter electrode.

The repetitive geometry and visual ambiguity evoke the Penrose Stairs and the lithograph Ascending and Descending by M. C. Escher.

Polymeric fibers composed of drug-loaded nanoparticles serve as a platform for formulating solid dosage forms. The drug used presents a pharmaceutical challenge due to its low water solubility; therefore, the use of these fibers helps increase the drug's solubility and bioavailability in the body.

Say goodbye to the dreaded needle — this Bacterial Cellulose Microneedle is here to make injections and blood tests a thing of the past. Grown, not manufactured, this tiny forest of spikes is your skin's new best friend ;)

This SEM image captures calcium dendritic growth resembling a snowflake, acquired during the evaluation of emerging calcium battery technologies.
