Science and Technology
I wanted to make my 007 roadster a true James Bond car by giving it some automation and futuristic capabilities. One of these capabilities is this original Fingerprint car automation project that was self-funded and self-motivated. Because of the open-source nature of most development chips, I could connect fingerprint sensors and arrays or relays to a “Seeeduino” and an “ESP32” development chips (advanced Arduino-like boards) and then integrate such isolated embedded systems into my 007 roadster vehicle. As a result, I can arm, operate, and generally control the vehicle with my fingerprint or from my phone via the Apple HomeKit protocol. It is an inexpensive yet reliable solution and can be used in other applications besides personal transportation – like elevating home security, deposit box access, weapons security, etc.

Negative pressure wound therapy (NPWT) is a prevalent treatment for traumatic, battlefield-related injuries. Wound contamination often occurs since greater than 75% of military wounds test positive for a pathogenic isolate at the time of injury. GRANUFOAM Silver by KCI is the most commonly used variation of commercially available antimicrobial foam for NPWT. However, silver nanoparticles are minimally effective against biofilm. This project incorporates a biofilm-specific bactericide into a PU foam matrix that is capable of reducing biofilm-bioburden in an in vivo porcine excision wound model. A PU foam was developed and infused with a 10% w/w concentration of CZ-01179 to compare against GRANUFOAM Silver which also has a 10% w/w concentration of silver nanoparticles.. An in vivo porcine full-thickness excision wound model was developed using Yorkshire pigs, 35-45 kg. The pigs were anesthetized and subjected to a surgical procedure creating four wounds, two with dimensions of 4×4 cm and two with dimensions of 3×3 cm, down to the fascia of the epaxial muscles. Upon completion of NPWT treatment, the pig was sacrificed and the wounds were harvested for microbiological quantification and histological analysis. The CFU/g of the tissue was attained through homogenization of the tissue followed by serial dilution. Histological analysis proceeded to understand the geography of biofilm in the tissue.
Inoculation of the full-thickness excision wounds resulted in ~8 log10 MRSA, A. baumannii, and natural flora CFU/
