Innovative Wearable Sweat Sensor Array for Real-Time Volatile Organic Compound Detection in Noninvasive Diabetes Monitoring.

Wearable sweat sensors are reshaping healthcare monitoring, providing real-time data on hydration and electrolyte levels with user-friendly, noninvasive devices. This paper introduces a highly portable two-channel microfluidic device for simultaneous sweat sampling and the real-time detection of volatile organic compound (VOC) biomarkers. This innovative wearable microfluidic system is tailored for monitoring diabetes through the continuous and noninvasive tracking of acetone and ammonia VOCs, and it seamlessly integrates with smartphones for easy data management.

Improving ultraviolet protection properties of cotton textiles using Zinc oxide (ZnO) nanomaterials: an approach for controlling occupational and environmental exposures.

Ultraviolet (UV) radiation exposure is one of the most important risk factor among workers. it may stimulate health outcomes such as multiple skin injuries and blinding eye diseases. So, UV protection is mainly important for people who expose to it.

Fabrication of an SPME fiber based on ZnO@GA nanorods coated onto fused silica as a highly efficient absorbent for the analysis of cancer VOCs in water and urine.

Analysis of volatile organic compounds (VOCs) secreted in urine, blood, breath, etc. is a new method for monitoring the metabolism and biochemistry of the human body. However, due to the complexity of samples, a pre-concentration step is necessary before the final analysis with gas chromatography-mass spectroscopy (GC-MS).

Macrophage repolarization using CD44-targeting hyaluronic acid-polylactide nanoparticles containing curcumin.

The aim of this study was to evaluate the efficiency of using a natural substance, curcumin, encapsulated in CD44-targeting hyaluronate-polylactide (HA-PLA) nanoparticles (NPs) for the modulation of macrophage polarity from the pro-inflammatory M1 to anti-inflammatory M2 phenotype. For this purpose, the characterization of the NPs was monitored using HNMR, FTIR, DLS and FE-SEM. The effects of curcumin-encapsulated HA-PLA NPs on the viability of LPS/IFN-γ stimulated peritoneal macrophages were determined using MTT assay.

An update on nanoparticle-based contrast agents in medical imaging.

Despite the great value of current exogenous contrast agents for providing main diagnostic information, they still have certain drawbacks such as short blood half life, nonspecific biodistribution, fast clearance, slight renal toxicity and poor contrast in fat patients. Nanoparticles (NPs) are used as novel contrast agents that represent a promising strategy for the non invasive diagnosis. As a platform, nanoparticulates are compatible for developing targeted contrast agents.

Development, In Vitro Characterization, Antitumor and Aerosol Performance Evaluation of Respirable Prepared by Self-nanoemulsification Method.

Poor water solubility and low oral bioavailability limit the clinical application of Erlotinib as an anticancer. For this purpose, we encapsulated erlotinib in the solid lipid nanoparticles (SLN) and designed a spray-dried dry powder inhalable (DPI) formulation. Erlotinib-loaded SLNs were prepared using self-nanoemulsifying and characterized for physicochemical properties.

Solid Lipid Nanoparticles and Nanostructured Lipid Carriers: Structure, Preparation and Application.

Lipid nanoparticles (LNPs) have attracted special interest during last few decades. Solid lipid nanoparticles (SLNs) and nanostructured lipid carriers (NLCs) are two major types of Lipid-based nanoparticles. SLNs were developed to overcome the limitations of other colloidal carriers, such as emulsions, liposomes and polymeric nanoparticles because they have advantages like good release profile and targeted drug delivery with excellent physical stability.
