“…Indeed, chiral electromagnetic fields have long been exploited to characterize chiral matter. More recently, their use has also been proposed for enantioselective biosensing [5,6], enantioselective separation [7,8], asymmetric catalysis [9], and nonlinear spectroscopic imaging [10,11]. In many of these applications, metallic nanostructures are utilized because their local plasmonic resonances can create concentrated electromagnetic fields [12].…”

To optimize the interaction between chiral matter and highly twisted light, quantities that can help characterize chiral electromagnetic fields near nanostructures are needed. Here, by analogy with Poynting's theorem, we formulate the time-averaged conservation law of optical chirality in lossy dispersive media and identify the optical chirality flux as an ideal far-field observable for characterizing chiral optical near fields. Bounded by the conservation law, we show that it provides precise information, unavailable from circular dichroism spectroscopy, on the magnitude and handedness of highly twisted fields near nanostructures.

“…Nevertheless, the effect of UV circularly polarized light has been suggested to explain the excesses observed [41]. This hypothesis is being tested by laboratory experiments [42][43][44][45][46][47] but the source of the CPL at the vicinity of the early solar system still needs to be assessed.…”

Abstract. Chondrites and comets have accreted primitive materials from the early solar system. Those materials include organics, water and other volatile components. The most primitive chondrites and comets have undergone few modifications on their respective parent bodies and can deliver to laboratories components that were present at the origin of the protosolar nebula. Here I present a review of the organic material and volatile components that have been studied in the most primitive chondrites, and the last data from the stardust mission about the cometary record. This paper focuses on materials that can be studied in laboratories, by mass spectrometry, ion probes or organic chemistry techniques.

“…Effect of UV circularly polarized light in space (gas phase or ices) has been suggested as an alternative way to induce excesses observed [34]. This hypothesis is being tested by laboratory experiments [35][36][37] but the source of the CPL at the vicinity of the early solar system still needs to be assessed. Chirality has been suggested to also occur in the IOM [38] and in hydroxy acids [39].…”

Abstract. Life requires specific conditions that have been, so far, only proven to meet on Earth. Though the chemical elements required to form living organism (C, H, N, O, S, etc) are widespread in the universe, the molecules that are crucial for Life, like nucleobases or amino acids, may not be so ubiquitous. The question of the formation of small and complex molecules is highly relevant to understand the process of Life origin. Carbonaceous chondrites are a class of meteorites rich in organic compounds and host potential precursors for the emergence of Life (organic matter and water). They could have been the source of complex molecules on the early Earth. This contribution will describe the main properties of the organic matter recovered from carbonaceous chondrites. However, the isotopic and molecular record of organic compounds is faded by secondary processes that occurred on the parent body of these meteorites. This results in complex signatures that raise multiple questions about the origin of organic compounds in the Solar System.
