“…Sensors derived from other carbon materials (graphene CNTs, CNFs) require additional steps of pattern transfer or printing onto flexible substrates, post their synthesis, to facilitate a complete microdevice fabrication. [235][236][237] LP-C not only offers a single-step fabrication, it even reduces the number of post-processing steps owing to its already functional large surface area. Its porous surface can indeed be further utilized to support other active nanoparticles to increase the sensitivity of the device toward the analyte, which increases its utility in sensor fabrication manifolds.…”

Fabricating electronic devices from natural, renewable resources is a common goal in engineering and materials science. In this regard, carbon is of special significance due to its biocompatibility combined with electrical conductivity and electrochemical stability. In microelectronics, however, carbon's device application is often inhibited by tedious and expensive preparation processes and a lack of control over processing and material parameters. Laser‐assisted carbonization is emerging as a tool for the precise and selective synthesis of functional carbon‐based materials for flexible device applications. In contrast to conventional carbonization via in‐furnace pyrolysis, laser‐carbonization is induced photo‐thermally and occurs on the time‐scale of milliseconds. By careful selection of the precursors and process parameters, the properties of this so‐called laser‐patterned carbon (LP‐C) such as porosity, surface polarity, functional groups, degree of graphitization, charge‐carrier structure, etc. can be tuned. In this critical review, a common perspective is generated on laser‐carbonization in the context of general carbonization strategies, fundamentals of laser‐induced materials processing, and flexible electronic applications, like electrodes for sensors, electrocatalysts, energy storage, or antennas. An attempt is made to have equal emphasis on material processing and application aspects such that this emerging technology can be optimally positioned in the broader context of carbon‐based microfabrication.

A genetic condition, termed as cystic fibrosis (CF) affecting numerous organs, including the lungs, pancreas, colon, liver, and reproductive system, is completely dormant and intrinsic. Better treatment and control of CF are facilitated by early diagnosis. With the advent of technological and healthcare developments, there have been tremendous advancements in detecting CF rapidly and administering therapeutics. Accordingly, these short communication overviews developments related to early diagnosis of CF with dermal stickers. Apart from this, the future perspectives are also appraised.

“…11,12 Electrochemical sensors have gained attention for their high sensitivity, fast response, and ease of miniaturization. [13][14][15] The electrochemical detection of creatinine began with the development of a potentiometric sensor by Meyerhoff and Rechnitz. 16 Later, enzyme-based amperometric creatinine sensors were developed by immobilizing enzymes onto the working electrode.…”

This work presents the development of a non-enzymatic electrochemical sensor for creatinine in a neutral medium using a cobalt-gold bimetallic nanoparticles modified platinum electrode. The voltammetric detection of creatinine in a neutral phosphate buffer was based on the formation of a soluble cobalt-creatinine complex. The sensor exhibited good selectivity and a detection limit (S/N = 3) of 2.25 mM with two linear ranges from 6.4 to 83.2 mM. The sensitivity of the sensor was 0.621 and 1.135 μA mM-1 cm-2 at lower (6.4 – 51.2 mM) and higher (51.2 – 83.2 mM) detection ranges, respectively. The sensor performance was validated using urine samples, and creatinine spiked urine samples.
