A perspective review of recent strategies involving the use of nano/microvehicles to address the key challenges associated with delivery and (bio)sensing at the cellular level is presented. The main types and characteristics of the different nano/microvehicles used for these cellular applications are discussed, including fabrication pathways, propulsion (catalytic, magnetic, acoustic or biologi...

Micro-scale printing and patterning of living cells has multiple applications including tissue engineering, cell signaling assays, and the fabrication of cell-based biosensors. In this work, a molecular printing instrument, the Bioforce Nano eNabler, was modified to enable micron-scale -quill-pen based printing of mammalian cells in a 3D hyaluronan/gelatin based hydrogel. Specifically, photo-in...

In this line, have gained considerable attention fabrication fluorescence-based Significant research efforts been made ...

Today, a strong research effort is directed towards the development and integration of new materials, especially of polymers and biomolecules which are essential in pharmaceutical, bioengineering, and sensing applications. In fact, patterning of organic and inorganic materials, in particular enabling precise positioning of different materials with nano and micro scale resolution over large area...

Ultrathin metal coordination Prussian blue (PB) nanoribbons with tunable width have been successfully synthesized. The morphology and microstructure of PB nanoribbons are characterized using UV-vis, FT-IR, AFM, TEM and XRD. PB nanoribbons synthesized possess an ultrathin thickness of approximately 1 nm and narrow width. The width of PB ribbons can be tuned by varying the chain length of polymer...

quinones are a class of compounds which have widespread importance in chemistry, biology and medicine. because of their appropriate performance in electron transferring rate, quinones are among the most applicable mediators in biosensors. recently, the effects of different non-metal substitutions on redox potential of quinone have been investigated to design suitable mediators for different ele...

aptamers define a new interesting class of receptor molecules with capability of binding to potentially any kind of molecules of interest. structurally, they are composed of nucleic acids (rna, dna or a mixture of both) with high specificity and affinity to amino acids, drugs, proteins and other molecules. apatmers are isolated from complex libraries of synthetic nucleic acids against the desir...
