Taylor, R. M., Miller, P. R., Ebrahimi, P., Polsky, R. & Baca, J. T. Minimally-invasive, microneedle-array extraction of interstitial fluid for comprehensive biomedical applications: transcriptomics, proteomics, metabolomics, exosome research, and biomarker identification. Lab. Anim. 52, 526–530 (2018). If you’re looking for a one-stop shop for sorting out your pimples, then you won’t find pimple patches better than the CORSX AC collection acne patch. The main ingredient aside from the hydrocolloid base is centella asiatica extract, which is typically used topically to heal wounds, repair the skin barrier and treat skin conditions such as psoriasis. The formula is both gentle and effective on the skin, so each patch leaves no trace after application, and is effective at busting breakouts pimples at any stage. During testing, we also found that these patches helped to bring ingrown hairs to the surface. She said: “You can experience gastrointestinal side-effects; there is a delay between taking the medication and the drug getting to where it’s needed in the body; doses need to be higher because a lot of the formulation is broken down in the gut, and if the patient is taking antibiotics, this can also contribute to antimicrobial drug-resistance.' Towards clinical trials

To analyse the statistical difference between two groups, unpaired one-tailed t-test with Welch’s correction was used. To analyse the statistical difference between each data point in two groups, two-way ANOVA with Sidak’s multiple-comparison test was used. For analysing the statistical difference between two or more groups one-way ANOVA with Tukey’s multiple-comparison test was used. Statistical significance of the data was calculated at 95% ( P< 0.05) confidence intervals. All values are expressed as mean ± s.d. GraphPad Prism 8 was used for all statistical analysis. We used four-parameter logistic or polynomial fit to calculate the LOD in the standard curves of bioassays. The LOD is defined as the analyte concentration corresponding to the mean fluorescence intensity of blank plus 3 σ. Origin 2016 was used to calculate the LOD.

Painless delivery

Drug Delivery and Translational Research. 12 (1): 67–78. doi: 10.1007/s13346-021-00922-9. PMID 33629222. S2CID 232047454. TEM images were obtained using a JEOL JEM-2100F field emission instrument. A drop of aqueous solution was dried on a carbon-coated grid, which had been made hydrophilic by glow discharge. SEM images were obtained using a FEI Nova 2300 field‐emission SEM at an acceleration voltage of 10 kV. The extinction spectra of plasmonic nanostructures were obtained using a Shimadzu UV-1800 spectrophotometer. Fluorescence mappings were recorded using LI-COR Odyssey CLx imaging system. The X-ray diffraction (XRD) patterns of the Fe 3O 4 nanoparticles were obtained using a Bruker D8-Advance X-ray powder diffractometer using Cu Kα radiation ( λ = 1.5406 Å) over the 2 θ range 10°–90°. Mechanical test Microneedling is mostly used on the face and may reduce the appearance of acne, scars, dark spots, wrinkles, and large pores. Transcutaneous delivery is the ideal method for delivering therapeutic reagents or vaccines into skin. With their promise of self-administration, cost-effective and high efficiency, microneedle patches have been studied intensively as therapeutic and vaccination delivery platform that replaces injection by syringe. This review aims to summarize the recent advancements of microneedle patches in application for drugs and vaccine delivery. With over 3000 micro-needles on each patch, Radara's patches have been found to reduce crow's feet by an average of 35% in four weeks.

In contrast to ISF extraction, microneedles functionalized with biorecognition elements can specifically capture target biomarkers in ISF, which can be followed by ex vivo analysis 17, 18. Direct exposure of microneedles to ISF allows the biorecognition elements on the microneedle to capture target biomarkers in situ, thus offering a promising technology for simple and efficient biodetection. However, physiological concentrations of the protein biomarkers in the ISF are usually lower compared to those in blood 4, 19. Moreover, analyte–antibody binding kinetics are deteriorated due to the dense tissue environment, which results in slower diffusion of target biomolecules to the sensor surface (that is, the microneedle surface), further lowering the probability of analyte capture and consequent signal intensity corresponding to the analyte. These challenges exacerbate the difficulty of detection of protein biomarkers in interstitial fluid. Despite the recent advances in multiplexed detection of biomarkers 20, the sensitivities of existing microneedle-based analytical methods are insufficient to detect (or quantify) most ISF protein biomarkers, which limits the development potential for diagnostic tests based on ISF biomarker levels. Most previous reports are limited to mice that have been intravenously injected with high concentrations of recombinant target markers as pseudo models, or to biomolecules present at relatively high levels (micrograms per millilitre in blood) 17. Finally, existing microneedle-based in vivo sampling and detection methods are limited to qualitative analysis in which the target biomarker concentration is represented as relative fluorescence intensity, absorbance value or normalized relative quantity 18, 20, 21. This limitation precludes quantitative comparisons of the biomarker concentrations across different experiments and across different laboratories for biomedical research and decreases opportunities for standardization of the cut-off values for clinical biomarkers. As opposed to in vitro diagnostics that involve sample acquisition (such as blood or urine) at a specific time point along the disease progression and analysis at a later point in time, in vivo diagnostics involving capture of target analytes from a dynamically varying matrix (for example, dermal ISF in the present case) is inherently a non-equilibrium condition. This is particularly true for the cases in which the target analyte concentration varies within the sampling timescales, for example, IL-6 level in LPS-stimulated mice. In such cases, the concentration determined using microneedle patches represents a time-average concentration of the analyte in ISF over the sampling period. From a diagnostic translation standpoint, this time-averaged concentration can be standardized by setting rigorous guidelines for microneedle administration (for example, administration time, location) and ex vivo analysis (for example, standard curve conditions). Detection and quantification of endogenous matricellular protein in periosteumFrequent and timely measurement of protein biomarkers is critical for disease monitoring and diagnostics in both biomedical research and clinical applications. Unfortunately, conventional longitudinal measurements require frequent blood draws in a short period, which may cause iatrogenic anaemia and increase morbidity of patients. Moreover, it is often impossible to repeatedly draw blood from small experimental animals, which can result in their death. The minimally invasive microneedle method represents a transformative approach to perform frequent, sensitive and accurate measurements of protein biomarkers in a longitudinal manner in the same mouse.
