  • Publication number: 20230295638
    Abstract: Provided herein are programmable condensate protein systems and nucleic acid constructs encoding the same. The protein system enables modular targeting of proteins of interest. Protein-peptide interaction domains (PPIDs) are incorporated to functionalize engineered condensates with the attributes of the recruited protein, resulting in a modular system that allows for diverse facile and reprogrammable applications, including in enzyme clustering of metabolic pathways. Colocalizing specific metabolic enzymes in these condensates results in functionalized organelles with which can be used to manipulate the output of engineered metabolic pathways for the production of a pharmaceutical precursor.

    Abstract: Systems and methods are described, and one method includes illuminating a target-of-interest (TI) with an RF energy configured to effect, over a time duration extending from a first time to a second time, an increase in a temperature of the TI. At a first detection time within the time duration, a first temperature NQR signal spectrum of the TI is detected, and a corresponding first temperature NQR spectrum data set is generates. At a second detection time, subsequent to the first detection time, a second temperature NQR signal spectrum of the TI is detected and corresponding second temperature NQR spectrum data set is output. Based at least in part on the first temperature NQR spectral dataset and the second temperature NQR spectral dataset, the TI is classified between including the SI and not including the SI.

  • Publication number: 20230268451
    Abstract: Disclosed herein are solar cells with kesterite-based absorbers that hold promise as a low-cost and durable technology to renewably produce electricity using solar energy conversion. The current state-of-the-art (SOA) for such kesterite solar cells is Cu2ZnSn(S,Se)4 and novel materials are required to suppress the formation bandgap-fluctuation- and charge-carrier-recombination-inducing defects and eventually to achieve solar cell efficiencies higher than the SOA. Three important material properties that govern the efficiency of a solar cell are the concentrations of performance-degrading defects, band gap, and chemical stability. Disclosed here is a stable material, specifically Cu2CdGe(S,Se)4, as a new candidate that can exhibit higher defect formation energies than Cu2ZnSnS4 and a nearly optimal bandgap, which can eventually result in higher solar-cell efficiencies in solar energy conversion.

  • Patent number: 11731099
    Abstract: A method for controlling the encapsulation efficiency and burst release of water soluble molecules from nanoparticle and microparticle formulations produced by the inverted Flash NanoPrecipitation (iFNP) process and subsequent processing steps is presented. The processing steps and materials used can be adjusted to tune the encapsulation efficiency and burst release of the encapsulated water-soluble material. The encapsulation efficiency of the soluble agent in the particles and the burst release of the soluble agent from the particles can be controlled by: (1) the copolymers used in the assembly or coating process, (2) the degree of crosslinking of the nanoparticle core, (3) the incorporation of small molecule or polymeric additives, and/or (4) the processing and release conditions employed.

  • Publication number: 20230248852
    Abstract: The invention described herein relates to colloidal particles useful for photoacoustic imaging. The particles comprise a photoacoustic imaging agent with an absorbance maximum or plateau in the range of wavelengths 700-1100 nm. The imaging agent also displays low optical absorbance at some wavelength in the range 700-1100 nm. This combination of high and low optical absorbance enables background subtraction in photoacoustic imaging applications. The imaging agent is an organic compound having low aqueous solubility so that it is stably encapsulated in the hydrophobic core of the particle. The particle is stabilized by a polymeric surface coating, and the polymeric stabilizing layer on the surface of the particle may contain targeting ligands for targeted diagnostics or therapeutic delivery. The particle core may also contain therapeutic agents or other imaging agents.

  • Publication number: 20230212640
    Abstract: Disclosed herein is a quantitative screen for the assessment of microbiome derived drug metabolism. The disclosed quantitative screen, named MDMQ-Screen, may be employed, inter alia, for assessing the impact of the human gut microbiome on drug metabolism. MDMQ-Screen is used to measure and explain inter-individual variability in drug metabolism. This information is crucial in explaining potential toxic effects of the administered drugs, as well variability in response to therapy between individuals. Inter alia, MDMQ-Screen can be used to assess unexplained variability in drug response and toxicity of already used medications; used in future drug development pipelines to aid in the design and interpretation of clinical trials; and used at bedside to assess the probability of drug response and toxicity and provide recommendations for therapeutic modifications in a personalized medicine manner.
