We report here on the fabrication of hard magnetic powder based micro-flux sources using micro-patterned films as templates or master structures. The micro-magnetic imprinting (μMI) process is simple and constituent materials final structures, commercial powders polymer, are inexpensive. structures may be transparent, either flexible rigid, depending choice polymer matrix used. peak-to-peak intensity z-component stray field measured above a test μMI structure made with spherical NdFeB...
Catecholamine-triggered β-adrenoceptor (β-AR) signaling is essential for the correct functioning of heart. Although both β1 - and β2 -AR subtypes are expressed in cardiomyocytes, drugs selectively targeting have proven this receptor as main target therapeutic effects beta blockers Here, we report a new strategy light-control activation by means photoswitchable with high level -/β2 selectivity. All reported molecules allow an efficient real-time optical control function vitro. Moreover, using...
Cellular attachment plays a vital role in the differentiation of pheochromocytoma (PC12) cells. PC12 cells are noradrenergic clonal isolated from adrenal medulla Rattus norvegicus and studied extensively as they have ability to differentiate into sympathetic neuron-like The effect several experimental parameters including (i) concentration nerve growth factor (NGF); (ii) substratum coatings, such poly-L-lysine (PLL), fibronectin (Fn), laminin (Lam); (iii) double coatings composed PLL/Lam...
Compositionally graded Fe–Pt thin films were prepared on stationary 100 mm Si substrates by magnetron sputtering a base target of Fe which piece Pt is asymmetrically positioned. Energy dispersive X-ray analysis was used to map the variation in film composition across substrate, as function size piece. A scanning polar Magneto-Optical-Kerr-Effect system probe influence and post-deposition annealing conditions (temperature time) coercivity. In this way, maximum coercivity achievable for could...
Blood circulation is the main distribution route for systemic delivery and possibility to manipulate red blood cells (RBCs) by attaching nanoparticles their surface provides a great opportunity cargo into tissues. Nanocarriers attached RBCs can be delivered specific organs orders of magnitude faster than if injected directly bloodstream. Another advantage shielding from recognition immune system, thereby increasing efficiency delivery. We present high-throughput microfluidic method that...
Angiotensin II (AngII) regulates cerebral circulation and binds with a similar affinity to AT
Magnetic particle force microscopy has been used to measure magnetic interactions between an array of thermomagnetically patterned hard micro-magnets and both superparamagnetic microspheres. Maximum interaction forces are experienced when the microspheres scan over interface reversed non-reversed zones, where stray field produced by micro-magnet is maximum. Comparison experimental simulated maps spheres validate assumptions concerning remanent magnetisation depth zones. This information in...
A compositionally graded SmCo film has been prepared by magnetron sputtering using a Co target partially covered Sm foil. The was deposited onto 100 mm thermally oxidised Si substrate and then annealed ex-situ. used as test sample to validate an in-house developed scanning MOKE (Magneto-Optic Kerr effect) system incorporating pulsed magnetic field source capable of producing fields high 10 T. 2D array hysteresis loops measured across the entire wafer. evolution in coercivity along selected...
Abstract Catecholamine‐triggered β‐adrenoceptor (β‐AR) signaling is essential for the correct functioning of heart. Although both β 1 ‐ and 2 ‐AR subtypes are expressed in cardiomyocytes, drugs selectively targeting have proven this receptor as main target therapeutic effects beta blockers Here, we report a new strategy light‐control activation by means photoswitchable with high level ‐/β selectivity. All reported molecules allow an efficient real‐time optical control function vitro....
Abstract Cyclic adenosine 3’,5’-monophosphate is an important second messenger molecule that regulates many downstream signaling pathways in cells. Detection of cAMP levels relies on screenings cell lysates or the use genetically encoded biosensors for detection living Genetically are, however, primarily used bioimaging and rarely high-throughput potential drug candidates. Here, we describe a quantitative fluorescence-based imaging method based measurements single We Epac149 biosensor to...
Abstract Biological systems are regulated by molecular interactions which tuned the concentrations of each molecules involved. Cells exploit this feature regulating protein expression, to adapt their responses overstimulation. Correlating events in single cells proteins involved can therefore provide important mechanistic insight into cell behavior. Unfortunately, quantification densities fluorescence imaging becomes non-trivial due diffraction limited resolution imaged volume. We show here...

High performance permanent magnets are key components in the development of more efficient electrical motors for electric and hybrid cars as well gearless wind turbines.
Summary Catecholamine-triggered β-adrenoceptor (β-AR) signaling is essential for the correct functioning of heart. Although both β 1 - and 2 -AR subtypes are expressed in cardiomyocytes, drugs selectively targeting have proven this receptor as main target therapeutic effects beta blockers Here, we report a new strategy spatiotemporal control activation by means light-regulated with high level -/β selectivity.
