The green alga, Chlamydomonas reinhardtii, is a model organism used in the study of photosynthesis and biotechnological research. Despite its importance, a complete set of genetic tools has yet to be developed. Here, we report the development of a new method for constructing a multi-gene pathway in Saccharomyces cerevisiae and integrating the assembled pathway into the nuclear genome of C. reinhardtii. To demonstrate the use of this method, we assembled and functionally expressed up to three reporter proteins (Ble, AphVIII, and GFP) simultaneously in the nucleus of C. reinhardtii. This new molecular tool should aid efforts to engineer microalgae for biofuel and biopharmaceutical production.

Biochips are widely applied to manipulate the geometrical morphology of stem cells in recent years. Patterned antenna-like pseudopodia are also probed to explore the influence of pseudopodia formation on gene delivery and expression on biochips. However, how the antenna-like pseudopodia affect gene transfection is unsettled and the underlying trafficking mechanism of exogenous genes in engineered single cells is not announced.

Efficient thermal generation from solar/electric energy in transparent films remains challenging due to the limited toolbox of high-performance thermal generation materials and methods for microstructure engineering. Here, we proposed a two-step strategy to introduce hierarchical wrinkles to the MXene composite films with high transparency, leading to upgraded photo/electrothermal conversion efficiency. Specifically, the thin film contains protic acid-treated MXene layers assembled with Ag nanowires (H-MXene/Ag NWs).

Transdermal drug delivery presents a compelling alternative to both needle injection and oral ingestion of medication, as it enhances patient adherence and convenience through its non-invasive and painless administration method. The use of microneedles penetrates the barrier of the stratum corneum, facilitating the sustained delivery of drugs across the skin. However, their efficacy has been limited by the slow diffusion of molecules and often requires external triggers.

Objectives: Pandoraea apista is notable for its multidrug resistance and is frequently identified in patients with cystic fibrosis or other chronic lung diseases, where it contributes to persistent lung infections. In this study, we describe a strain of P. apista harboring the bla, isolated from the bronchoalveolar lavage (BAL) fluid of an inpatient in China.

Unlabelled: Dry eye disease is a multifactorial disorder of the ocular surface with increasing global prevalence, yet no universally accepted "gold standard" exists for its diagnosis or severity assessment. Tear matrix metalloproteinase 9 (MMP-9) is widely recognized as a valuable biomarker for dry eye, yet there remains a critical need for a simple, accurate, and broadly applicable method for its quantification. This study aims to develop and evaluate a Schirmer strip-based Eu-time resolved fluorescence immunochromatography (Eu-TRFICO) method for the quantitative detection of MMP-9 in tears.
