ABSTRACT = {Amorphous selenium nanoparticles have been synthesized by pulsed laser ablation in 
liquids. After undergoing a thermal treatment at 121°C for 60 minutes, the amorphous 
nanoparticles crystallized into trigonal ones. The antimicrobial properties of both 
amorphous and trigonal nanoparticles have been compared; and the amorphous ones 
displayed better antibacterial and antifungal properties compared to the trigonal ones. 
Specifically, Methicillin-resistant <i>Staphylococcus aureus</i> (MRSA), Ampicillin-resistant 
<i>Escherichia coli</i>, <i>Pseudomonas aeruginosa</i>, <i>Staphylococcus epidermidis</i>, and <i>Candida 
albicans</i> were almost completely inhibited in the presence of amorphous selenium 
nanoparticles at 0.025 microgram/ml concentrations after 24 hours of in vitro culture, 
compared to controls (no nanoparticles). In summary, such a high sensitivity of these 
bacterial and fungal strains to low concentrations of amorphous selenium nanoparticles 
warrants further investigation to develop efficient anti-bacterial and anti-fungal treatments.},
