Just have to put this out there! Don't want to leave anyone behind!
=======================
"To explore ozone profiling using DIAL technique from space based platforms, an highly efficient, allsolid-
state, diode pumped, conductively cooled, single longitudinal mode and high-energy 1-micron to UV
wavelength conversion technology to primarily generate UV wavelengths of 308 nm and 320 nm has been
developed. This effort is a collaborative effort among Sandia National Labs, Fibertek, Inc. and NASA
Langley Research Center1. This tunable UV transmitter technology has chem-bio sensing applications for
NASA, defense, and Homeland Security Agency (HSA) missions. In the case of NASA, this UV converter
technology provides a path for the development of compact, electrically controllable, and rugged chem-bio
sensors specifically designed for investigating geological and mineralogical compositions as well as
exploring precursors of life signature on various bodies of our Solar system. Besides NASA applications,
this technology is suited for several HSA applications. For e.g., Tryptophan (amino acid generated by
protein digestion), absorbs at 280 nm and emits over a range of 300-400 nm wavelengths with a resonance
peak at 330 nm.
Besides ozone related wavelengths, the LRRP UV transmitter technology"....
...."Recent work using UV LIF technique has shown that under suitable conditions, it is possible to
detect as few as 5 to 10 bacteria on a surface, and zepta molar {10-21 mole} of poly-aromatic hydrocarbons
(PAHs). The specificity of Raman spectral molecular finger-prints has made the technique of great value in
a number of areas including biochemistry and biophysics, early detection of cancers, chem-bio agents and
for identifying minerals on planetary surfaces. LIF and laser Raman spectroscopy are considered sensitive
techniques for providing reliable information on characteristics of organic molecules and the molecules of
life. Use of excitation wavelengths below 250 nm, endogenous and Raman emission of target molecules
can be measured without mutual interference."
=======================
Would that include Earth's planetary system?
aha! The Pahs............... the real or the created ones?
=======================
..."Abundant polycyclic aromatic hydrocarbons discovered in the fresh fracture surfaces of the Martian
meteorite have stimulated new interest in the search for past life on Mars. These polyaromatic chains
present in a Martian meteorite indicating probable past life signature. Deep-UV excitation of precursors
such as kerogens and lignins could provide insight into biological precursors2. These are insoluble
macromolecular hydrocarbons with low hydrogen content containing aromatic and polyaromatic
components and are considered precursors for origins of life. Efforts are underway to devise sensitive
techniques for the detection of lignins and kerogens.'.....
======================
The precursors of life??? why do we need
artificial genes then?
=========================
...."The Chem-Bio Sensing Scheme
The experimental arrangement for analyzing responses from chem-bio species due to deep-UV
excitation under development is illustrated in Figure 1. In this scheme, a tunable deep UV laser transmitter
is used for excitation. An acousto-optic tunable filter (AOTF) is utilized for UV LIF and resonance Raman
Spectroscopic techniques. The fluorescence and Raman signals emanated from target species is collected
using a telescope and selectively routed into an imaging spectrograph or an AOTF. The spectrally selective
filtering is succeeded by detection and data processing tools that are commercially available. The proposed
experimental scheme will be utilized for investigating mineralogical samples and/or simulants pertaining to"........
