Cuttlefish ink found promising for cancer treatment

Researchers have found that cuttlefish ink—a black suspension sprayed by cuttlefish to deter predators—contains nanoparticles that strongly inhibit the growth of cancerous tumors in mice. The nanoparticles consist mostly ...

Shape-encoded dynamic assembly of mobile micromachines

Field-directed and self-propelled colloidal assembly can be used to build micromachines to perform complex motions and functions, although their integration as heterogenous components with specified structures, dynamics and ...

Raising fluid walls around living cells

Cell culture plates that are in everyday use in biology can be effectively transformed into microfluidic devices, opening paths for biologists to miniaturize cell-based workflows. In a recent report, Ph.D. researcher Cristian ...

Nanoscale magnetic imaging of ferritin in a single cell

In life sciences, the ability to measure the distribution of biomolecules inside a cell in situ is an important investigative goal. Among a variety of techniques, scientists have used magnetic imaging (MI) based on the nitrogen ...

Cellular microRNA detection with miRacles

MicroRNAs (miRNAs) are short noncoding regulatory RNAs that can repress gene expression post-transcriptionally and are therefore increasingly used as biomarkers of disease. Detecting miRNAs can be arduous and expensive as ...

Nano-bio-computing lipid nanotablet

Nanoparticles can be used as substrates for computation, with algorithmic and autonomous control of their unique properties. However, scalable architecture to form nanoparticle-based computing systems is lacking at present. ...
