Nanomedicine has shown the potential to improve therapeutic efficacy in psoriatic skin. The metallic nanocarriers such as gold, selenium, silver, zinc, iron, titanium, and copper have currently emerged as promising and highly effective treatment options for psoriasis as they offer several advantages like favorable physicochemical properties, enhanced drug-loading, improved skin penetration, and permeation. Metallic nanocarriers can be functionalized and tailored to specific therapeutic needs, making them highly effective at delivering anti-psoriatic drugs directly to the targeted areas without causing any adverse effects. The gold nanoparticles are known for their high biocompatibility and anti-inflammatory properties, while silver nanoparticles exhibit strong antimicrobial effects that are beneficial in managing psoriatic skin infections. Selenium, zinc, and iron nanoparticles contribute antioxidant and anti-inflammatory benefits, which are essential in mitigating the reactive oxidative stress, suppressing cytokines, and interleukins inflammatory mediators associated with psoriasis. Through metallic nanoparticles, it is possible to achieve controlled release, which maintains a steady rate of drug diffusion and skin penetration and delivers drugs more precisely, lowering the risk of systemic toxicity and improving patient compliance.

One of the most important advances in this area is the creation of nanomedicines that target cancer cells, which facilitates the progress of precise therapeutic interventions. Efficient drug delivery into tumor cells remains one of the critical challenges in cancer therapy. However, cancer-cell-targeted nanomedicines that function within the intricate milieu of the tumor microenvironment have shown potential to improve therapeutic efficiency. Epigallocatechin gallate (EGCG), the major phytochemical in Phyllanthus emblica (amla), is known for its anticancer and anti-inflammatory properties. In this study, we developed pH-responsive calcium carbonate nanoparticles (CCNPs) as a nanocarrier for EGCG to enhance its intracellular delivery and therapeutic efficacy. EGCG was physically adsorbed onto the surface of CCNPs. The synthesized nanoparticles were characterized using UV–visible spectroscopy, scanning electron microscopy (SEM), dynamic light scattering (DLS), zeta potential analysis, Fourier transform infrared spectroscopy (FTIR), and X-ray diffraction (XRD). In-vitro drug release studies demonstrated a sustained and more prominent release of EGCG at the acidic pH (4.8) typical of the tumor microenvironment. The biological activity of EGCG-loaded CCNPs was evaluated using the MTT assay and apoptosis analysis. The results showed significant cytotoxicity against colorectal cancer cells (COLO-320 DM), while blank CCNPs exhibited low toxicity and high biocompatibility. Intracellular uptake studies further confirmed the preferential accumulation of nanoparticles within colorectal cancer cells. Flow cytometry-based apoptosis assays revealed that EGCG-conjugated CCNPs induced considerable cancer cell death.

The nanostructures were synthesised using the pulsed Nd-YAG ablation technique, which entailed submerging small, high-quality tin particles in deionised water. The particles were coarsely crushed manually, filtered, and compacted into a solid tablet for 60 min using a 5-t hydraulic press. This production method utilised a pulse count of up to 200 laser shots, a wavelength of 1064 nm, spot size of 2.3 mm, focal length of 10 cm, and an energy of 500 mJ to examine the influence of surface shape on antibacterial activity levels. X-ray diffraction (XRD) analysis identified rhombohedral crystals mainly characterised by three Bragg peaks. Scanning electron microscopy (SEM) of the surface showed distinct and reasonably homogenous semispherical nanoparticles (NPs) rather than the expected porosity. The NPs exhibited an average size of 193.53 nm, in agreement with electron dispersive spectroscopy (EDS), which indicated that the oxygen-to-tin ratio closely approximated that of tin oxide (SnO2). In addition, the vibrational spectra measured with a Fourier transform infrared (FTIR) spectrometer indicated the synthesis of amber-coloured SnO2 NPs, confirming their formation by the preparation process, as well as their light scattering and absorption characteristics. In addition, using UV–visible spectroscopy, the resulting energy gap was 2.4 eV, within the normal range of energy gap for SnO2. The generated NPs were discovered to suppress the growth of fungi and bacteria, indicating that they may prevent the development of these entities.
