Towards the Development of an Optical Biosensor for the Detection of Human Blood for Forensic Analysis [PDF]

Sensors
Blood is a common biological fluid in forensic investigations, offering significant evidential value. Currently employed presumptive blood tests often lack specificity and are sample destructive, which can compromise downstream analysis.

Modeling a Coronal Loop Heated by Magnetohydrodynamic Turbulence Nanoflares [PDF]

The Astrophysical Journal, 2005
We model the hydrodynamic evolution of the plasma confined in a coronal loop, 30,000 km long, subject to the heating of nanoflares due to intermittent magnetic dissipative events in the MHD turbulence produced by loop footpoint motions. We use the time-dependent distribution of energy dissipation along the loop obtained from a hybrid shell model ...

Pt-Decorated Gold Nanoflares for High-Fidelity Phototheranostics: Reducing Side-Effects and Enhancing Cytotoxicity toward Target Cells. [PDF]

Angewandte Chemie
Functionalized with the Au-S bond, gold nanoflares have emerged as promising candidates for theranostics. However, the presence of intracellular abundantly biothiols compromises the conventional Au-S bond, leading to unintended release of cargoes and ...

Statistical Signatures of Nanoflare Activity. II. A Nanoflare Explanation for Periodic Brightenings in Flare Stars Observed by NGTS [PDF]

The Astrophysical Journal, 2020
Abstract Several studies have documented periodic and quasi-periodic signals from the time series of dMe flare stars and other stellar sources. Such periodic signals, observed within quiescent phases (i.e., devoid of larger-scale microflare or flare activity), range in a period from 1 to 1000 s and hence have been tentatively linked to ...

High-resolution Observations of a Small-scale Cancellation Nanoflare: Supporting Evidence for the Cancellation Nanoflare Model

The Astrophysical Journal Letters
An analytical cancellation nanoflare model has recently been established to show the fundamental role that ubiquitous small-scale cancellation nanoflares play in solar atmospheric heating.

Intermittency in MHD turbulence and coronal nanoflares modelling [PDF]

Nonlinear Processes in Geophysics, 2005
High resolution numerical simulations, solar wind data analysis, and measurements at the edges of laboratory plasma devices have allowed for a huge progress in our understanding of MHD turbulence.

Solar nanoflares in different spectral ranges

Astronomy & Astrophysics
The rates and other characteristics of solar nanoflares were measured for the same area of the Sun in different extreme-ultravioilet (EUV) channels to find how the main properties of nanoflares depend on the spectral range.

Two-Color-Based Nanoflares for Multiplexed MicroRNAs Imaging in Live Cells. [PDF]

Nanotheranostics, 2018
MicroRNAs (miRNAs) have become an ideal biomarker candidate for early diagnosis of diseases. But various diseases involve changes in the expression of different miRNAs. Therefore, multiplexed assay of miRNAs in live cells can provide critical information

Smart DNA sensors-based molecular identification for cancer subtyping. [PDF]

Smart Mol, 2023
Molecular subtyping of cancer is crucial for understanding the development of disease and predicting tumor behavior. This review focuses on the advanced strategies of molecular subtyping using DNA‐based biosensors for the identification of cancer subtypes based on different biomarkers, including cells, extracellular vesicles (EVs), and microRNAs ...

Nephrotoxicity Assessment with Human Kidney Tubuloids Using Spherical Nucleic Acid-Based mRNA Nanoflares

Nano letters (Print), 2021
Drug-induced nephrotoxicity represents an important cause of acute kidney injury with associated patient morbidity and mortality and is often responsible for termination of drug development, after extensive resource allocation.
