Immigration and Customs Enforcement agents were escorted by Horry County Police officers through Myrtle Beach International Airport last week, but details about their actions remain murky.

Construction is kicking off on a new hotel coming to the Grand Strand. Here’s the plan for the new Hampton Inn & Suites.

Myrtle Beach will spend nearly half a million dollars supporting affordable workforce housing.

The developer of a controversial new Horry County housing plan will hear input from the public. Here’s what concerned residents should know.

Bimetallic silver–copper nanoparticles (Ag/Cu NPs) were synthesized via a green approach using polysaccharides extracted from Lycoperdon perlatum, an edible mushroom traditionally used for wound healing. Two fractions were obtained: an aqueous fraction (FAq) and an alkaline fraction (FAk), which acted as reducing and stabilizing agents, respectively. The nanoparticles were characterized by UV–Vis spectroscopy, dynamic light scattering (DLS), zeta potential measurements, SEM‒EDS, and transmission electron microscopy (TEM). FAq-derived formulations exhibited higher colloidal stability (up to −45.40 mV) and smaller hydrodynamic sizes (~ 75.6 nm), whereas FAk formulations showed lower stability and greater dispersion. TEM analysis revealed quasispherical nanoparticles (< 10 nm) in FAk⁻3 and aggregated structures in FAq⁻3 associated with a polysaccharide matrix. Antimicrobial activity was evaluated against Staphylococcus aureus and Escherichia coli. The 3:2:1 FAq⁻2 formulation showed the highest efficacy, with minimum inhibitory concentration (MIC) values ≤ 0.0073 mg/mL. In vivo assays demonstrated enhanced wound healing, achieving ≥90% closure by day 6. Overall, the FAq-derived nanoparticles exhibited superior biological performance, highlighting the potential of L. perlatum polysaccharides for producing Ag/Cu nanoparticles with promising antimicrobial and wound-healing properties. To our knowledge, this is the first study to validate the traditional wound-healing use of L. perlatum by employing purified polysaccharide fractions for the green synthesis of bimetallic nanomaterials.
