Abstract
This review discusses the progress in the assembly of photosynthetic biohybrid systems using enzymes and microbes as the biocatalysts which are capable of utilising light to reduce carbon dioxide to solar fuels. We begin by outlining natural photosynthesis, an inspired biomachinery to develop artificial photosystems, and the rationale and motivation to advance and introduce biological substrates to create more novel, and efficient, photosystems. The case studies of various approaches to the development of CO2-reducing microbial semi-artificial photosystems are also summarised, showcasing a variety of methods for hybrid microbial photosystems and their potential. Finally, approaches to investigate the relatively ambiguous electron transfer mechanisms in such photosystems are discussed through the presentation of spectroscopic techniques, eventually leading to what this will mean for the future of microbial hybrid photosystems.

Abstract
Acoustic trapping is a non-contact particle manipulation method that holds great potential for performing automated assays. We demonstrate an aluminium acoustic trap in combination with attenuated total reflection Fourier-transform infrared spectroscopy (ATR-FTIR) for detection of E. coli in water. The thermal conductivity of aluminium was exploited to thermo-electrically heat and hold the acoustic trap at the desired assay temperature of 37 °C. Systematic characterisation and optimisation of the acoustic trap allowed high flow rates while maintaining high acoustic trapping performance. The ATR element serves not only as a reflector for ultrasound standing wave generation but also as a sensing interface. The enzyme conversion induced by alkaline phosphatase-labelled bacteria was directly monitored in the acoustic trap using ATR-FTIR spectroscopy. Sequential injection analysis allowed automated liquid handling, including non-contact bacteria retention, washing and enzyme-substrate exchange within the acoustic trap. The presented method was able to detect E. coli concentrations as low as 1.95 × 106 bacteria per mL in 197 min. The demonstrated ultrasound assisted assay paves the way to fully automated bacteria detection devices based on acoustic trapping combined with ATR-FTIR spectroscopy.

Abstract
![]()
In
this work, we introduce polarimetric balanced detection as a
new attenuated total reflection (ATR) infrared (IR) sensing scheme,
leveraging unequal effective thicknesses achieved with laser light
of different polarizations. We combined a monolithic widely tunable
Vernier quantum cascade laser (QCL-XT) and a multibounce ATR IR spectroscopy
setup for analysis of liquids in a process analytical setting. Polarimetric
balanced detection enables simultaneous recording of background and
sample spectra, significantly reducing long-term drifts. The root-mean-square
noise could be improved by a factor of 10 in a long-term experiment,
compared to conventional absorbance measurements obtained via the
single-ended optical channel. The sensing performance of the device
was further evaluated by on-site measurements of ethanol in water,
leading to an improved limit of detection (LOD) achieved with polarimetric
balanced detection. Sequential injection analysis was employed for
automated injection of samples into a custom-built ATR flow cell mounted
above a zinc sulfide multibounce ATR element. The QCL-XT posed to
be suitable for mid-IR-based sensing in liquids due to its wide tunability.
Polarimetric balanced detection proved to enhance the robustness and
long-term stability of the sensing device, along with improving the
LOD by a factor of 5. This demonstrates the potential for new polarimetric
QCL-based ATR mid-IR sensing schemes for in-field measurements or
process monitoring usually prone to a multitude of interferences.
