Organic Light-Emitting Diodes In article number 2202866, Chul Hoon Kim, Kyoung-Ho Seung Yoon Ryu, and co-workers demonstrate a unique abnormal approach for organic light-emitting diodes (OLEDs) to enhance the external quantum efficiency using antibiotic ampicillin. Electroluminescence photoluminescence scattering by ampicillin microstructure make highly efficient top-emission OLEDs possible. Th...

Vaginal group B streptococcus (GBS) and Escherichia coli isolates were tested for their susceptibilities to ampicillin. All 414 GBS isolates tested were susceptible to ampicillin; the MIC at which 90% of the isolates were inhibited (MIC90) was 0.125 microg/ml, and the range was 0.06 to 0.25 microg/ml. The MIC50 for the 342 E. coli isolates tested was 4.0 microg/ml, and 27% were resistant to amp...

We show here that silver nanoparticles (AgNP) were intrinsically antibacterial, whereas gold nanoparticles (AuNP) were antimicrobial only when ampicillin was bound to their surfaces. Both AuNP and AgNP functionalized with ampicillin were effective broad-spectrum bactericides against Gram-negative and Gram-positive bacteria. Most importantly, when AuNP and AgNP were functionalized with ampicilli...
