1. The document discusses two new diagnostic tests: one that can determine fetal sex from the mother's blood and one that can detect influenza infection using gold nanoparticles. 2. The fetal sex determination test analyzes DNA from the mother's blood to identify Y chromosome sequences and correctly identified sex with high accuracy after 7 weeks of gestation. 3. The influenza detection test uses gold nanoparticles linked to antibodies that aggregate around influenza viruses, allowing samples to be tested in minutes at low cost to help control the spread of infection.

4. Determination of fetal sex provides an alternative to invasive techniques for some heritable disorders. It detects influenza in minutes, offering advantages to combat the flu Gold Nanoparticles Used to Diagnose Flu in Minutes Tests That Use DNA from Mother’s Blood to Determine Sex of Fetus Often Effective

5. The availability of a reliable noninvasive alternative to determine fetal sex would reduce unintended fetal losses and would presumably be welcomed by pregnant women carrying fetuses at risk for disorders

7. using maternal blood Largest effects Real-time quantitative polymerase chain reaction (RTQ-PCR) Test performance was high if performed using RTQ-PCR on a blood sample taken at a time during pregnancy when sufficient cell-free fetal DNA was present (7 weeks' gestation or later), with the best performance after 20 weeks' gestation.

10. We've known for a long time that you can use antibodies to capture viruses and that nanoparticles have different traits based on their size, done is combine to create a diagnostic test that is rapid and highly sensitive.
