In this work, a novel adsorbent with stabilizing of PAMAM dendrimer on the surface of sand was successfully synthesized and used to remove NP from water. The characterization of the adsorbent was performed by XRD, FTIR, TEM, and FE-SEM. Batch and column studies were conducted to evaluate the performance of the adsorbent. It was found that Freundlich isotherm and pseudo-second order models are perfectly stimulated the adsorption behavior and kinetic rate of NP uptake. In column study, first the effect of bed depth, flow rate and initial concentration of NP on the performance of the adsorbent were evaluated then the breakthrough curve for each condition was drawn. Finally, Thomas model constants to describe NP adsorption were calculated. As the result of the experiments, it might be concluded that in conventional water treatment plants which the removal of NP is negligible, the use of synthesized adsorbent as a filter media can be a promising way to selectively remove NP from water.

The use of proteins as intracellular probes and therapeutic tools is often limited by poor intracellular delivery. One approach to enabling intracellular protein delivery is to transform proteins into spherical nucleic acid (proSNA) nanoconstructs, with surfaces chemically modified with a dense shell of radially oriented DNA that can engage with cell-surface receptors that facilitate endocytosis. However, proteins often have a limited number of available reactive surface residues for DNA conjugation such that the extent of DNA loading and cellular uptake is restricted.

Organelles are specialized subunits within cells which carry out vital functions crucial to cellular survival and form a tightly regulated network. Dysfunctions in any of these organelles are linked to numerous diseases impacting virtually every organ system in the human body. Targeted delivery of therapeutics to specific organelles within the cell holds great promise for overcoming challenging diseases and improving treatment outcomes through the minimization of therapeutic dosage and off-target effects.

Article Synopsis
- Oral mucosal wounds are susceptible to inflammation and complications due to exposure to microorganisms, which can hinder daily activities and diminish quality of life.
- A novel therapeutic nanoplatform, DATS@Arg-EA-SA, has been developed to target these wounds by combining guanidinated dendritic peptides with diallyl trisulfide (DATS), providing both antimicrobial and anti-inflammatory effects.
- This nanoplatform effectively eliminates various bacteria, including drug-resistant strains like MRSA, and enhances healing by promoting the transition of inflammatory cells and alleviating pain, making it a promising solution for oral wound treatment.
